Mike Reed noted (https://bugzilla.novell.com/show_bug.cgi?id=421330) that the driver was incorrectly returning a SUCCESS status if the driver's request to the firmware to abort a command failed. By doing so, the mid-layer believed, incorrectly, that the command has completed and has been returned (ultimately clearing scsi_cmnd.request_buffer) yet the driver still has the command. What should correctly happen is a mid-layer escalation (device-reset, etc.) of recovery during which the driver will eventually return the outstanding commands to the mid-layer.

The LLDs previously used DID_BUS_BUSY or DID_ERROR which followed the cmd->retries limit, but DID_TRANSPORT_DISRUPTED was skipping that check so it could have caused a problem with tape commands. This patch has DID_TRANSPORT_DISRUPTED check the cmd->retries/cmd->allowed.

CPUs declared as "Processor" should use the Local SAPIC's 'processor_id', and CPUs declared as "Device" should use the 'uid'. Note that for "Processor" declarations, even if a '_UID' child object exists, it has no bearing with respect to mapping Local SAPICs (see section 5.2.11.13 - Local SAPIC Structure; "Advanced Configuration and Power Interface Specification", Revision 3.0b). This patch changes the lsapic mapping logic to rely on the distinction of how the processor object was declared - the mapping can't just try both types of matches regardless of declaration type and rely on one failing as is currently being done.

The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

I think &hso_net->net->dev is more intuitive for the error message, so I've used that. I've also added missing line endings on the error messages and set our local rfkill structure element to NULL on failure so we don't try to call rfkill_unregister on driver removal if we failed to register at all. The patch below Works For Me (TM); the device is detected fine, can be removed without problems and connects ok. I'll have a prod at why the rfkill stuff isn't working next, but I believe this cleanup of the error handling is appropriate no matter what the issue with registration is.

Then UBIFS allocates empty LEBs in the reverse order that they are discovered i.e. they are added to, and removed from, the front of a list. That creates a gap in the middle of the LPT. The function dirtying the LPT tree (for the purpose of small model garbage collection) assumed that a gap could only occur at the very end of the LPT and stopped dirtying prematurely, which in turn resulted in the LPT running out of space - something that is designed to be impossible.

In fact, they only worked because the ACPI device of the discrete, the wrong one, got used (via int10). So ACPI functions were poking on the wrong hardware used which is a sever bug. The next patch provides support for above ThinkPads to be able to switch brightness via the legacy thinkpad_acpi driver and automatically detect when to use it. Original commit message from Matthew Garrett: Vendors often ship machines with a choice of integrated or discrete graphics, and use the same DSDT for both. As a result, the ACPI video module will locate devices that may not exist on this specific platform. Attempt to determine whether the device exists or not, and abort the device creation if it doesn't. http://bugzilla.kernel.org/show_bug.cgi?id=9614 Signed-off-by: Thomas Renninger Acked-by: Zhang Rui Signed-off-by: Andi Kleen Signed-off-by: Len Brown --- drivers/acpi/glue.c | 40 ++++++++++++++++++++++++++++++++++++++++ drivers/acpi/video.c | 7 ++++++- include/acpi/acpi_bus.h | 2 ++ 3 files changed, 48 insertions(+), 1 deletion(-) diff --git a/drivers/acpi/glue.c b/drivers/acpi/glue.c index 24649ada08d..adec3d15810 100644 --- a/drivers/acpi/glue.c +++ b/drivers/acpi/glue.c @@ -140,6 +140,46 @@ struct device *acpi_get_physical_device(acpi_handle handle) EXPORT_SYMBOL(acpi_get_physical_device); +/* ToDo: When a PCI bridge is found, return the PCI device behind the bridge + * This should work in general, but did not on a Lenovo T61 for the + * graphics card.

This can happen in the direct I/O path when a direct I/O write fails due to ENOSPC. In this case the xfs_ioend_t will still be queued (ie xfs_end_io_direct() does not know that the I/O failed so can't force the xfs_ioend_t to be flushed synchronously). When we truncate a file on unlink we don't know to wait for these xfs_ioend_ts and we can have a use-after-free situation if the inode is reclaimed before the xfs_ioend_t is finally processed. As was suggested by Dave Chinner lets wait for all I/Os to complete when truncating the file size to zero.

This leads to problems where an allocation group has only enough blocks for *some* of the allocations required for the directory modification. After the first N allocations, the remaining blocks in the allocation group drops below the total reservation, and subsequent allocations fail because the allocator will not allow the allocation to proceed if the AG does not have the enough blocks available for the entire allocation total. This results in an ENOSPC occurring after an allocation has already occurred. This results in aborting the directory operation (leaving the directory in an inconsistent state) and cancelling a dirty transaction, which results in a filesystem shutdown. Avoid the problem by reflecting the number of blocks allocated in any directory expansion in the total number of blocks available to the modification in progress. This prevents a directory modification from being aborted part way through with an ENOSPC.

Currently we just assert that header magic number matches, but in production systems that is not present and we add a corrupted transaction to the list to be processed. This results in a kernel oops later when processing the corrupted transaction. Instead, if we detect a corrupted transaction, abort recovery and leave the user to clean up the mess that has occurred.

There was a race in the kmap_coherent() implementation. While we guarded against preemption, there was nothing preventing eviction of the pre-faulted fixmap entry from the UTLB. Under certain workloads this would result in the fixmap entries used for cache colouring being evicted from the UTLB in the midst of a copy_page(). In addition to pre-faulting, we also make sure to preserve the PTEs in the kernel page table and introduce a cached PTE for kmap_coherent() usage. This follows a similar change on MIPS ("[MIPS] Fix aliasing bug in copy_to_user_page / copy_from_user_page").

The biggest problem is guaranteeing that tag 0 is always used for non-NCQ commands. Due to the way blk-tag is implemented and how SCSI starts and finishes requests, such guarantee can't be made. I'm not sure whether this would actually break any low level driver but it doesn't look like a good idea to break such assumption given the frailty of ATA controllers. So, for the time being, keep using the old dumb in-libata qc allocation.

But in the old implementation, when we want to extend a bucket, we just move half number of xattrs to the new bucket. This works in most cases, but if we are lucky enough we will move 2 xattrs into 2 different buckets. This means that an xattr from the previous bucket cannot be found anymore.

Having them all in one file was a frequent source of merge conflicts. However, in the next merge, 49997d75152b3d23c53b0fa730599f2f74c92c65, there was another conflict. Some of the bindings removed from booting-without-of.txt were mistakenly added back in and the copies in dts-bindings were kept as well. This patch re-removes "Freescale Display Interface" and "Freescale on board FPGA" and fixes the table of contents.

A timestamp is taken, a test is preformed and if it detects that an interrupt occurred that did tracing, it tries again. The problem arises if the timestamp code itself causes a trace. The detection will detect this and loop again. The difference between this and an interrupt doing tracing, is that this will fail every time, and cause an infinite loop. Currently, we test if the loop happens 1000 times, and if so, it will produce a warning and disable the ring buffer. The problem with this approach is that it makes it difficult to perform some types of tracing (tracing the timestamp code itself). Each trace entry has a delta timestamp from the previous entry. If a trace entry is reserved but and interrupt occurs and traces before the previous entry is commited, the delta timestamp for that entry will be zero. This actually makes sense in terms of tracing, because the interrupt entry happened before the preempted entry was commited, so one may consider the two happening at the same time. The order is still preserved in the buffer. With this idea, instead of trying to get a new timestamp if an interrupt made it in between the timestamp and the test, the entry could simply make the delta zero and continue. This will prevent interrupts or tracers in the timer code from causing the above loop.

Unlike other similar routines, account_group_exec_runtime() could be called "implicitly" from within scheduler after exit_notify(). This means we can race with the parent doing release_task(), we can't just check ->signal != NULL. Change __exit_signal() to do spin_unlock_wait(&task_rq(tsk)->lock) before __cleanup_signal() to make sure ->signal can't be freed under task_rq(tsk)->lock. Note that task_rq_unlock_wait() doesn't care about the case when tsk changes cpu/rq under us, this should be OK. Thanks to Ingo who nacked my previous buggy patch.

When userland detected that this ioctl was supported (by version number check), it used it in a racy way -- dispatch delayed swap, wait for vblank, continue rendering. As there was no mechanism for it to wait for the swap to finish, sometimes it would render before the swap and garbage would be displayed on the screen. By removing the ioctl and returning -EINVAL, userland returns to its previous, correct rendering path of waiting for a vblank then dispatching a swap. The only path that could have used this ioctl correctly was page flipping, which relied on only one client running and emitting wait-for-vblank-before-rendering in the command stream. That path also falls back correctly, at the performance cost of not being able to queue up rendering before the flip occurs.

It's initialized to jiffies minus one minute on EH entry. However, when new links are initialized after PMP is probed, new links have zero for this timestamp resulting in long wait depending on the current jiffies. This patch makes last_set considered iff ATA_EHI_DID_RESET is set, in which case last_reset is always initialized. As an added precaution, WARN_ON() is added so that warning is printed if last_reset is in future. This problem is spotted and debugged by Shane Huang.

When the iw_cxgb3 module's cxgb3_client "add" func gets called by the cxgb3 module, the iwarp driver ends up calling the ethtool ops get_drvinfo function in cxgb3 to get the fw version and other info. Currently the iwarp driver grabs the rtnl lock around this down call to serialize. As of 2.6.27 or so, things changed such that the rtnl lock is held around the call to the netdev driver open function. Also the cxgb3_client "add" function doesn't get called if the device is down. So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device, the iw_cxgb3 add func gets called with the rtnl_lock held. If you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func gets called without the rtnl_lock held. The former causes the deadlock, the latter does not. In addition, there are iw_cxgb3 sysfs handlers that also can call down into cxgb3 to gather the fw and hw versions. These can be called concurrently on different processors and at any time. Thus we need to push this serialization down in the cxgb3 driver get_drvinfo func. The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

One authored by Andy Burns and another authored by Suresh Siddha. Due to that, I'm applying the one that has less CodingStyle errors. I'm also adding both comments and the SOB's for both patches, since they are both interesting} Suresh Siddha commented: Alexey Fisher reported: > resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000 > 0xcfefffff PCI Bus 0000:01 BAR base is located in the middle of the 4K page and the hardcoded size argument makes the request span two pages causing the conflict. Fix the hard coded size argument in ioremap(). Andy Burns commented: I have already sent this patch on the linux-dvb list, but it didn't get much attention, so re-sending direct, I hope you all don't mind. While attempting to run mythtv in a xen domU, I encountered problems loading the driver for my saa7134 card, with an error from ioremap(). This error was due to the driver allocating an incorrectly sized mmio area, which was trapped by xen's permission checks, but this would go un-noticed on a kernel without xen. My card has a 1K sized mmio area, I've had information that other cards have 2K areas, perhaps others have different sizes, yet the driver always attempts to map 4K. I realise that the granularity of mapping is the page size, which typically would be 4K, but unless the card's base address happens to fall on a 4K boundary (mine does not) then the base+4K will end up spanning two pages, and this is when the error occurs under xen. My patch uses the pci_resource_len macro to determine the size required for the user's particular card, instead of the hardcoded 4K value. I've tested with a couple of printk() inside ioremap() that the start address and size do get rounded to the closest page boundary. With this patch I am able to successfully load the saa7134 driver and run mythtv under xen with my card, subject to correct pollirq settings in case of shared IRQ, I am still seeing occasional DMA panics, which I think are related to swiotlb handling by dom0/domU, usually the panic occurs when changing mux, once tuned to a mux, 12 hour continuous recordings are possible without errors.

When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with 2.6.24, I was met with an oops [1]. The problem is relevant to 2.6.25/26-rc also. dvb_frontend_init() was called either from re-creation of the kdvb-fe0 thread - seems unlikely, or someone called dvb_frontend_reinitialise(), causing this path in the thread - really unlikely, as I can't find any call-site for it. Either way, quite a number of drivers call dvb_usb_generic_rw() [2] without checking the validity of the relevant member in the dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw() sanity-check and fail (rather than loading from 0x120) seems reasonable defensive programming [3], in light of it being called in this way. The problem with this, is that drivers don't check the return code of the init call [4]. Does it make sense to cook a patch which allows the failure to be propagated back up, or am I missing something else?

This patch addes a new kernel API to the ring buffers called: tracing_on() tracing_off() When tracing_off() is called, all ring buffers will not be able to record into their buffers. tracing_on() will enable the ring buffers again. These two act like an on/off switch. That is, there is no counting of the number of times tracing_off or tracing_on has been called. A new file is added to the debugfs/tracing directory called tracing_on This allows for userspace applications to also flip the switch. echo 0 > debugfs/tracing/tracing_on disables the tracing. echo 1 > /debugfs/tracing/tracing_on enables it. Note, this does not disable or enable any tracers. It only sets or clears a flag that needs to be set in order for the ring buffers to write to their buffers. It is a global flag, and affects all ring buffers. The buffers start out with tracing_on enabled. There are now three flags that control recording into the buffers: tracing_on: which affects all ring buffer tracers. buffer->record_disabled: which affects an allocated buffer, which may be set if an anomaly is detected, and tracing is disabled. cpu_buffer->record_disabled: which is set by tracing_stop() or if an anomaly is detected. tracing_start can not reenable this if an anomaly occurred. The userspace debugfs/tracing/tracing_enabled is implemented with tracing_stop() but the user space code can not enable it if the kernel called tracing_stop(). Userspace can enable the tracing_on even if the kernel disabled it. It is just a switch used to stop tracing if a condition was hit. tracing_on is not for protecting critical areas in the kernel nor is it for stopping tracing if an anomaly occurred. This is because userspace can reenable it at any time. Side effect: With this patch, I discovered a dead variable in ftrace.c called tracing_on. This patch removes it.

But the bit 0, which doesn't indicate any error, must be ignored. The bit 0 is used as the query flag at _OSC invocation time. Some platforms clear it during _OSC evaluation, but the others don't. On latter platforms, current acpi_run_osc() mis-detects error when _OSC is evaluated with query flag set because it doesn't ignore the bit 0. Because of this, the __acpi_query_osc() always fails on such platforms. And this is the cause of the problem that pci_osc_control_set() doesn't work since the commit 4e39432f4df544d3dfe4fc90a22d87de64d15815 which changed pci_osc_control_set() to use __acpi_query_osc().

But the link driver can easily figure out whether to turn on IRQ balancing based on the IRQ model (PIC/IOAPIC/etc), so we can get rid of that external interface. It's better for the driver to figure this out at init-time. If we set it externally via the x86 code, the interface reduces modularity, and we depend on the fact that acpi_process_madt() happens before we process the kernel command line.

With the PMB enabled, only P1SEG and up are covered by the PMB mappings, meaning that situations where out-of-bounds physical addresses are read from will lead to TLB reset after the PMB miss, allowing for use cases like dd if=/dev/mem to reset the TLB. Fix this up to make sure the reference is between __MEMORY_START (phys) and __pa(high_memory). This is coherent across all variants of sh/sh64 with and without MMU, though the PMB bug itself is only applicable to SH-4A parts.

This causes the silent output problem on some Dell laptops. Also, the hp_switch check is screwed up when a line-in or a mic-in jack exists. This is added as an additional output, but hp_switch check doesn't take it into account. This patch fixes these issues: simplify hp_switch check by using the NID instead of bool, and clean up / fix the toggle of HP pins in unsol event handler code.

Currently, the time since the last congestion event, which is stored in variable last_cong, is reset whenever there is a state change into TCP_CA_Open. This includes transitions of the type TCP_CA_Open->TCP_CA_Disorder->TCP_CA_Open which are not associated with backoff of cwnd. The patch changes last_cong to be updated only on transitions into TCP_CA_Open that occur after experiencing the congestion-related states TCP_CA_Loss, TCP_CA_Recovery, TCP_CA_CWR.

Currently the iwarp driver grabs the rtnl lock around this down call to serialize. As of 2.6.27 or so, things changed such that the rtnl lock is held around the call to the netdev driver open function. Also the cxgb3_client "add" function doesn't get called if the device is down. So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device, the iw_cxgb3 add func gets called with the rtnl_lock held. If you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func gets called without the rtnl_lock held. The former causes the deadlock, the latter does not. In addition, there are iw_cxgb3 sysfs handlers that also can call down into cxgb3 to gather the fw and hw versions. These can be called concurrently on different processors and at any time. Thus we need to push this serialization down in the cxgb3 driver get_drvinfo func. The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

Wysocki" Date: Wed, 12 Nov 2008 23:22:35 +0100 Subject: x86, hibernate: fix breakage on x86_32 with CONFIG_NUMA set Impact: fix crash during hibernation on 32-bit NUMA The NUMA code on x86_32 creates special memory mapping that allows each node's pgdat to be located in this node's memory. For this purpose it allocates a memory area at the end of each node's memory and maps this area so that it is accessible with virtual addresses belonging to low memory. As a result, if there is high memory, these NUMA-allocated areas are physically located in high memory, although they are mapped to low memory addresses. Our hibernation code does not take that into account and for this reason hibernation fails on all x86_32 systems with CONFIG_NUMA=y and with high memory present. Fix this by adding a special mapping for the NUMA-allocated memory areas to the temporary page tables created during the last phase of resume. Signed-off-by: Rafael J.

Miller" Date: Wed, 12 Nov 2008 14:32:54 -0800 Subject: niu: Fix readq implementation when architecture does not provide one. This fixes a TX hang reported by Jesper Dangaard Brouer. When an architecutre cannot provide a fully functional 64-bit atomic readq/writeq, the driver must implement it's own. This is because only the driver can say whether doing something like using two 32-bit reads to implement the full 64-bit read will actually work properly. In particular one of the issues is whether the top 32-bits or the bottom 32-bits of the 64-bit register should be read first. There could be side effects, and in fact that is exactly the problem here. The TX_CS register has counters in the upper 32-bits and state bits in the lower 32-bits. A read clears the state bits. We would read the counter half before the state bit half. That first read would clear the state bits, and then the driver thinks that no interrupts are pending because the interrupt indication state bits are seen clear every time. Fix this by reading the bottom half before the upper half. Tested-by: Jesper Dangaard Brouer Signed-off-by: David S.

I think it's reasonable to disallow freeze tasks in the root cgroup. And then we can avoid fork overhead when freezer subsystem is compiled but not used. Also make writing invalid value to freezer.state returns EINVAL rather than EIO. This is more consistent with other cgroup subsystem.

Note, if above rescuing happend, the Mlocked and the Unevictable field mismatching happend in /proc/meminfo. but it doesn't cause any real trouble. ======================================================= [ INFO: possible circular locking dependency detected ] 2.6.28-rc2-mm1 #2 ------------------------------------------------------- lvm/1103 is trying to acquire lock: (&cpu_hotplug.lock){--..}, at: [] get_online_cpus+0x29/0x50 but task is already holding lock: (&mm->mmap_sem){----}, at: [] sys_mlockall+0x4e/0xb0 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (&mm->mmap_sem){----}: [] check_noncircular+0x82/0x110 [] might_fault+0x4a/0xa0 [] validate_chain+0xb11/0x1070 [] might_fault+0x4a/0xa0 [] __lock_acquire+0x263/0xa10 [] lock_acquire+0x7c/0xb0 (*) grab mmap_sem [] might_fault+0x4a/0xa0 [] might_fault+0x7b/0xa0 [] might_fault+0x4a/0xa0 [] copy_to_user+0x30/0x60 [] filldir+0x7c/0xd0 [] sysfs_readdir+0x11a/0x1f0 (*) grab sysfs_mutex [] filldir+0x0/0xd0 [] filldir+0x0/0xd0 [] vfs_readdir+0x86/0xa0 (*) grab i_mutex [] sys_getdents+0x6b/0xc0 [] syscall_call+0x7/0xb [] 0xffffffff -> #2 (sysfs_mutex){--..}: [] check_noncircular+0x82/0x110 [] sysfs_addrm_start+0x2c/0xc0 [] validate_chain+0xb11/0x1070 [] sysfs_addrm_start+0x2c/0xc0 [] __lock_acquire+0x263/0xa10 [] lock_acquire+0x7c/0xb0 (*) grab sysfs_mutex [] sysfs_addrm_start+0x2c/0xc0 [] mutex_lock_nested+0xa5/0x2f0 [] sysfs_addrm_start+0x2c/0xc0 [] sysfs_addrm_start+0x2c/0xc0 [] sysfs_addrm_start+0x2c/0xc0 [] create_dir+0x3f/0x90 [] sysfs_create_dir+0x29/0x50 [] _spin_unlock+0x25/0x40 [] kobject_add_internal+0xcd/0x1a0 [] kobject_set_name_vargs+0x3a/0x50 [] kobject_init_and_add+0x2d/0x40 [] sysfs_slab_add+0xd2/0x180 [] sysfs_add_func+0x0/0x70 [] sysfs_add_func+0x5c/0x70 (*) grab slub_lock [] run_workqueue+0x172/0x200 [] run_workqueue+0x10f/0x200 [] worker_thread+0x0/0xf0 [] worker_thread+0x9c/0xf0 [] autoremove_wake_function+0x0/0x50 [] worker_thread+0x0/0xf0 [] kthread+0x42/0x70 [] kthread+0x0/0x70 [] kernel_thread_helper+0x7/0x1c [] 0xffffffff -> #1 (slub_lock){----}: [] check_noncircular+0xd/0x110 [] slab_cpuup_callback+0x11f/0x1d0 [] validate_chain+0xb11/0x1070 [] slab_cpuup_callback+0x11f/0x1d0 [] mark_lock+0x35d/0xd00 [] __lock_acquire+0x263/0xa10 [] lock_acquire+0x7c/0xb0 [] slab_cpuup_callback+0x11f/0x1d0 [] down_read+0x43/0x80 [] slab_cpuup_callback+0x11f/0x1d0 (*) grab slub_lock [] slab_cpuup_callback+0x11f/0x1d0 [] notifier_call_chain+0x3c/0x70 [] _cpu_up+0x84/0x110 [] cpu_up+0x4b/0x70 (*) grab cpu_hotplug.lock [] kernel_init+0x0/0x170 [] kernel_init+0xb5/0x170 [] kernel_init+0x0/0x170 [] kernel_thread_helper+0x7/0x1c [] 0xffffffff -> #0 (&cpu_hotplug.lock){--..}: [] validate_chain+0x5af/0x1070 [] dev_status+0x0/0x50 [] __lock_acquire+0x263/0xa10 [] lock_acquire+0x7c/0xb0 [] get_online_cpus+0x29/0x50 [] mutex_lock_nested+0xa5/0x2f0 [] get_online_cpus+0x29/0x50 [] get_online_cpus+0x29/0x50 [] lru_add_drain_per_cpu+0x0/0x10 [] get_online_cpus+0x29/0x50 (*) grab cpu_hotplug.lock [] schedule_on_each_cpu+0x32/0xe0 [] __mlock_vma_pages_range+0x85/0x2c0 [] __lock_acquire+0x285/0xa10 [] vma_merge+0xa9/0x1d0 [] mlock_fixup+0x180/0x200 [] do_mlockall+0x78/0x90 (*) grab mmap_sem [] sys_mlockall+0x81/0xb0 [] syscall_call+0x7/0xb [] 0xffffffff other info that might help us debug this: 1 lock held by lvm/1103: #0: (&mm->mmap_sem){----}, at: [] sys_mlockall+0x4e/0xb0 stack backtrace: Pid: 1103, comm: lvm Not tainted 2.6.28-rc2-mm1 #2 Call Trace: [] print_circular_bug_tail+0x7c/0xd0 [] validate_chain+0x5af/0x1070 [] dev_status+0x0/0x50 [] __lock_acquire+0x263/0xa10 [] lock_acquire+0x7c/0xb0 [] get_online_cpus+0x29/0x50 [] mutex_lock_nested+0xa5/0x2f0 [] get_online_cpus+0x29/0x50 [] get_online_cpus+0x29/0x50 [] lru_add_drain_per_cpu+0x0/0x10 [] get_online_cpus+0x29/0x50 [] schedule_on_each_cpu+0x32/0xe0 [] __mlock_vma_pages_range+0x85/0x2c0 [] __lock_acquire+0x285/0xa10 [] vma_merge+0xa9/0x1d0 [] mlock_fixup+0x180/0x200 [] do_mlockall+0x78/0x90 [] sys_mlockall+0x81/0xb0 [] syscall_call+0x7/0xb Signed-off-by: KOSAKI Motohiro Tested-by: Kamalesh Babulal Cc: Lee Schermerhorn Cc: Christoph Lameter Cc: Heiko Carstens Cc: Nick Piggin Cc: Hugh Dickins Cc: Rik van Riel Cc: Peter Zijlstra Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- mm/mlock.c | 16 ++++++---------- 1 file changed, 6 insertions(+), 10 deletions(-) diff --git a/mm/mlock.c b/mm/mlock.c index 008ea70b7af..a6da2aee940 100644 --- a/mm/mlock.c +++ b/mm/mlock.c @@ -66,14 +66,10 @@ void __clear_page_mlock(struct page *page) putback_lru_page(page); } else { /* - * Page not on the LRU yet.

The data was apparently delayed by 1 byte and got ridiculous data out of the touchscreen driver, very strange. As everything looked normal in the spi, touchscreen and dma logs, I contacted the Atmel support and they triggered me on a new HW bug that appeared in the Rev B SPI controller. The problem is that the SPI controller on the Rev B needs that the software reset is performed two times so that it's performed correctly. Applying the patch below solves the issue on my Rev B board. I've tested it as well on my Rev A evaluation kit and it has apparently no unwanted side effect, things continue to work as expected.

Wong + +Description +----------- + +This driver implements support for the Analog Devices ADT7462 chip family. + +This chip is a bit of a beast. It has 8 counters for measuring fan speed. It +can also measure 13 voltages or 4 temperatures, or various combinations of the +two. See the chip documentation for more details about the exact set of +configurations. This driver does not allow one to configure the chip; that is +left to the system designer. + +A sophisticated control system for the PWM outputs is designed into the ADT7462 +that allows fan speed to be adjusted automatically based on any of the three +temperature sensors. Each PWM output is individually adjustable and +programmable. Once configured, the ADT7462 will adjust the PWM outputs in +response to the measured temperatures without further host intervention. This +feature can also be disabled for manual control of the PWM's. + +Each of the measured inputs (voltage, temperature, fan speed) has +corresponding high/low limit values. The ADT7462 will signal an ALARM if +any measured value exceeds either limit. + +The ADT7462 samples all inputs continuously. The driver will not read +the registers more often than once every other second. Further, +configuration data is only read once per minute. + +Special Features +---------------- + +The ADT7462 have a 10-bit ADC and can therefore measure temperatures +with 0.25 degC resolution. + +The Analog Devices datasheet is very detailed and describes a procedure for +determining an optimal configuration for the automatic PWM control. + +The driver will report sensor labels when it is able to determine that +information from the configuration registers. + +Configuration Notes +------------------- + +Besides standard interfaces driver adds the following: + +* PWM Control + +* pwm#_auto_point1_pwm and temp#_auto_point1_temp and +* pwm#_auto_point2_pwm and temp#_auto_point2_temp - + +point1: Set the pwm speed at a lower temperature bound. +point2: Set the pwm speed at a higher temperature bound. + +The ADT7462 will scale the pwm between the lower and higher pwm speed when +the temperature is between the two temperature boundaries. PWM values range +from 0 (off) to 255 (full speed). Fan speed will be set to maximum when the +temperature sensor associated with the PWM control exceeds temp#_max. + diff --git a/drivers/hwmon/Kconfig b/drivers/hwmon/Kconfig index 1c44f5c47aa..c709e821f04 100644 --- a/drivers/hwmon/Kconfig +++ b/drivers/hwmon/Kconfig @@ -159,6 +159,16 @@ config SENSORS_ADM9240 This driver can also be built as a module.

The driver reports selected and actual +frequency. If spread spectrum mode is enabled, the driver also reports by what +percent the clock signal is being spread, which should be between 0 and -0.5%. +All frequencies are reported in KHz. + +The ICS932S401 monitors all inputs continuously. The driver will not read +the registers more often than once every other second. + +Special Features +---------------- + +The clocks could be reprogrammed to increase system speed.

These protocols use a single wire for +communication between the master (HDQ/1-Wire controller) and the slave +(HDQ/1-Wire external compliant device). + +A typical application of the HDQ/1-Wire module is the communication with battery +monitor (gas gauge) integrated circuits. + +The controller supports operation in both HDQ and 1-wire mode. The essential +difference between the HDQ and 1-wire mode is how the slave device responds to +initialization pulse.In HDQ mode, the firmware does not require the host to +create an initialization pulse to the slave.However, the slave can be reset by +using an initialization pulse (also referred to as a break pulse).The slave +does not respond with a presence pulse as it does in the 1-Wire protocol. + +Remarks: +======== +The driver (drivers/w1/masters/omap_hdq.c) supports the HDQ mode of the +controller. In this mode, as we can not read the ID which obeys the W1 +spec(family:id:crc), a module parameter can be passed to the driver which will +be used to calculate the CRC and pass back an appropriate slave ID to the W1 +core. + +By default the master driver and the BQ slave i/f +driver(drivers/w1/slaves/w1_bq27000.c) sets the ID to 1. +Please note to load both the modules with a different ID if required, but note +that the ID used should be same for both master and slave driver loading. + +e.g: +insmod omap_hdq.ko W1_ID=2 +inamod w1_bq27000.ko F_ID=2 + -- cgit v1.2.3 From 4e17e1db96474af5620e3259754df4cb1c46521c Mon Sep 17 00:00:00 2001 From: Rodolfo Giometti Date: Wed, 12 Nov 2008 13:27:12 -0800 Subject: Add c2 port support C2port implements a two wire serial communication protocol (bit banging) designed to enable in-system programming, debugging, and boundary-scan testing on low pin-count Silicon Labs devices.

Under qemu there is a race between the TDxE read-and-clear and the SCxTDR write. While on hardware it can be gauranteed that the read-and-clear will happen prior to the character being written out, no such assumption can be made under emulation. As this path happens with IRQs off and the hardware itself doesn't care about the ordering, move the SCxTDR write until after the read-and-clear.

This warning isn't necessarily justified though because the generic powerpc platform code calls set_irq_type() (which in turn calls __irq_set_trigger) with information from the device tree to establish the interrupt mappings, regardless of whether the PIC can actually set a type. A platform's irq_chip might not have a set_type function for a variety of reasons, for example: the platform may have the type essentially hard-coded, or as in the case for Cell interrupts are just messages past around that have no real concept of type, or the platform could even have a virtual PIC as on the PS3.

An extraneous 'else' slipped into a code fragment being moved from release_lockspace() to dlm_release_lockspace(). The result of the unwanted 'else' is that dlm threads and structures are not stopped and cleaned up when the final dlm lockspace is removed.

So the "need_reconnect" flag has been broken out from those two state fields (need reconnect was not mutually exclusive from some of the other possible tid and ses states).

When interfaces are deleted, either because the device was disconnected or because of a configuration change, the extra attribute files and child endpoint devices may get left behind. This is because the core removes them before calling device_del(). But during device_del(), after the driver is unbound the core will reinstall altsetting 0 and recreate those extra attributes and children. The patch prevents this by adding a flag to record when the interface is in the midst of being unregistered. When the flag is set, the attribute files and child devices will not be created.

It doesn't check for the STS_HALT status bit before taking action. The mere fact that the STS_FATAL bit is set means that something bad has happened and the controller needs to be reset. With the old code this test could never succeed because the STS_HALT bit was masked out from the status. I anticipate that this will prevent the occasional "irq X: nobody cared" problem people encounter when their EHCI controllers die.

The newish (2.6.27) CDC ACM event notification mechanism sends messages (IN to the host) which are short enough to fit in most FIFOs. That means that with some peripheral controller drivers (evidently not the ones used to verify the notification code!!) the completion callback can be issued before queue() returns. The deadlock would come because the completion callback and the event-issuing code shared a spinlock. Fix is trivial: drop that lock while queueing the message.

Declare a sockaddr struct and cast it to the proper type. Also, eliminate the protocolType field in the TCP_Server_Info struct. It's redundant since we have a sa_family field in the sockaddr anyway. We may need to revisit this if SCTP is ever implemented, but for now this will simplify the code. CIFS over IPv6 also has a number of problems currently. This fixes all of them that I found.

There's just one callback code used on all those boards. So, it makes no sense on keeping this as a callback. Since there were some OOPS reported on tvaudio on kerneloops.org, this patch removes this callback, adding the code at the only place were it is called: inside chip_tread. A flag were added to indicate the need for a kernel thread to set stereo mode on cards that needs it. Using this more direct approach simplifies the code, making it more robust against human errors.

Not all tvaudio chips allow controlling bass/treble. So, the driver has a table with a flag to indicate if the chip does support it. Unfortunately, the handling of this logic were broken for a very long time (probably since the first module version). Due to that, an OOPS were generated for devices that don't support bass/treble. This were the resulting OOPS message before the patch, with debug messages enabled: tvaudio' 1-005b: VIDIOC_S_CTRL BUG: unable to handle kernel NULL pointer dereference at 00000000 IP: [<00000000>] *pde = 22fda067 *pte = 00000000 Oops: 0000 [#1] SMP Modules linked in: snd_hda_intel snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_hwdep snd soundcore tuner_simple tuner_types tea5767 tuner tvaudio bttv bridgebnep rfcomm l2cap bluetooth it87 hwmon_vid hwmon fuse sunrpc ipt_REJECT nf_conntrack_ipv4 iptable_filter ip_tables ip6t_REJECT xt_tcpudp nf_conntrack_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables x_tables ipv6 dm_mirrordm_multipath dm_mod configfs videodev v4l1_compat ir_common 8139cp compat_ioctl32 v4l2_common 8139too videobuf_dma_sg videobuf_core mii btcx_risc tveeprom i915 button snd_page_alloc serio_raw drm pcspkr i2c_algo_bit i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support sr_mod cdrom sg ata_generic pata_acpi ata_piix libata sd_mod scsi_mod ext3 jbdmbcache uhci_hcd ohci_hcd ehci_hcd [last unloaded: soundcore] Pid: 15413, comm: qv4l2 Not tainted (2.6.25.14-108.fc9.i686 #1) EIP: 0060:[<00000000>] EFLAGS: 00210246 CPU: 0 EIP is at 0x0 EAX: 00008000 EBX: ebd21600 ECX: e2fd9ec4 EDX: 00200046 ESI: f8c0f0c4 EDI: f8c0f0c4 EBP: e2fd9d50 ESP: e2fd9d2c DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process qv4l2 (pid: 15413, ti=e2fd9000 task=ebe44000 task.ti=e2fd9000) Stack: f8c0c6ae e2ff2a00 00000d00 e2fd9ec4 ebc4e000 e2fd9d5c f8c0c448 00000000 f899c12a e2fd9d5c f899c154 e2fd9d68 e2fd9d80 c0560185 e2fd9d88 f8f3e1d8 f8f3e1dc ebc4e034 f8f3e18c e2fd9ec4 00000000 e2fd9d90 f899c286 c008561c Call Trace: [] ? chip_command+0x266/0x4b6 [tvaudio] [] ? chip_command+0x0/0x4b6 [tvaudio] [] ? i2c_cmd+0x0/0x2f [i2c_core] [] ? i2c_cmd+0x2a/0x2f [i2c_core] [] ? device_for_each_child+0x21/0x49 [] ? i2c_clients_command+0x1c/0x1e [i2c_core] [] ? bttv_call_i2c_clients+0x14/0x16 [bttv] [] ? bttv_s_ctrl+0x1bc/0x313 [bttv] [] ? bttv_s_ctrl+0x0/0x313 [bttv] [] ? __video_do_ioctl+0x1f84/0x3726 [videodev] [] ? sock_aio_write+0x100/0x10d [] ? kmap_atomic_prot+0x1dd/0x1df [] ? enqueue_hrtimer+0xc2/0xcd [] ? copy_from_user+0x39/0x121 [] ? __video_ioctl2+0x1aa/0x24a [videodev] [] ? do_notify_resume+0x768/0x795 [] ? getnstimeofday+0x34/0xd1 [] ? autoremove_wake_function+0x0/0x33 [] ? video_ioctl2+0xf/0x13 [videodev] [] ? vfs_ioctl+0x50/0x69 [] ? do_vfs_ioctl+0x239/0x24c [] ? sys_ioctl+0x40/0x5b [] ? syscall_call+0x7/0xb [] ? cpuid4_cache_sysfs_exit+0x3d/0x69 ======================= Code: Bad EIP value.

Copyright 2003 Intel Corporation - -3. What is MSI/MSI-X? - -Message Signaled Interrupt (MSI), as described in the PCI Local Bus -Specification Revision 2.3 or later, is an optional feature, and a -required feature for PCI Express devices. MSI enables a device function -to request service by sending an Inbound Memory Write on its PCI bus to -the FSB as a Message Signal Interrupt transaction. Because MSI is -generated in the form of a Memory Write, all transaction conditions, -such as a Retry, Master-Abort, Target-Abort or normal completion, are -supported. - -A PCI device that supports MSI must also support pin IRQ assertion -interrupt mechanism to provide backward compatibility for systems that -do not support MSI. In systems which support MSI, the bus driver is -responsible for initializing the message address and message data of -the device function's MSI/MSI-X capability structure during device -initial configuration. - -An MSI capable device function indicates MSI support by implementing -the MSI/MSI-X capability structure in its PCI capability list. The -device function may implement both the MSI capability structure and -the MSI-X capability structure; however, the bus driver should not -enable both. - -The MSI capability structure contains Message Control register, -Message Address register and Message Data register. These registers -provide the bus driver control over MSI. The Message Control register -indicates the MSI capability supported by the device. The Message -Address register specifies the target address and the Message Data -register specifies the characteristics of the message. To request -service, the device function writes the content of the Message Data -register to the target address. The device and its software driver -are prohibited from writing to these registers. - -The MSI-X capability structure is an optional extension to MSI. It -uses an independent and separate capability structure. There are -some key advantages to implementing the MSI-X capability structure -over the MSI capability structure as described below. - - - Support a larger maximum number of vectors per function. - - - Provide the ability for system software to configure - each vector with an independent message address and message - data, specified by a table that resides in Memory Space. - - - MSI and MSI-X both support per-vector masking. Per-vector - masking is an optional extension of MSI but a required - feature for MSI-X. Per-vector masking provides the kernel the - ability to mask/unmask a single MSI while running its - interrupt service routine. If per-vector masking is - not supported, then the device driver should provide the - hardware/software synchronization to ensure that the device - generates MSI when the driver wants it to do so. - -4. Why use MSI? - -As a benefit to the simplification of board design, MSI allows board -designers to remove out-of-band interrupt routing. MSI is another -step towards a legacy-free environment. - -Due to increasing pressure on chipset and processor packages to -reduce pin count, the need for interrupt pins is expected to -diminish over time. Devices, due to pin constraints, may implement -messages to increase performance. - -PCI Express endpoints uses INTx emulation (in-band messages) instead -of IRQ pin assertion. Using INTx emulation requires interrupt -sharing among devices connected to the same node (PCI bridge) while -MSI is unique (non-shared) and does not require BIOS configuration -support. As a result, the PCI Express technology requires MSI -support for better interrupt performance. - -Using MSI enables the device functions to support two or more -vectors, which can be configured to target different CPUs to -increase scalability. - -5.

A successful MSI request (using pci_enable_msi()) switches -a device's interrupt mode to MSI mode. A pre-assigned IOAPIC vector -stored in dev->irq will be saved by the PCI subsystem and a new -assigned MSI vector will replace dev->irq. - -To return back to its default mode, a device driver should always call -pci_disable_msi() to undo the effect of pci_enable_msi().

To emphasize this reason, for example, a device -may be capable for supporting the maximum of 32 vectors while its -software driver usually may request 4 vectors. It is recommended -that the device driver should call this function once during the -initialization phase of the device driver. - -Unlike the function pci_enable_msi(), the function pci_enable_msix() -does not replace the pre-assigned IOAPIC dev->irq with a new MSI -vector because the PCI subsystem writes the 1:1 vector-to-entry mapping -into the field vector of each element contained in a second argument. -Note that the pre-assigned IOAPIC dev->irq is valid only if the device -operates in PIN-IRQ assertion mode. In MSI-X mode, any attempt at -using dev->irq by the device driver to request for interrupt service -may result in unpredictable behavior. - -For each MSI-X vector granted, a device driver is responsible for calling -other functions like request_irq(), enable_irq(), etc. to enable -this vector with its corresponding interrupt service handler. It is -a device driver's choice to assign all vectors with the same -interrupt service handler or each vector with a unique interrupt -service handler. - -5.3.1 Handling MMIO address space of MSI-X Table - -The PCI 3.0 specification has implementation notes that MMIO address -space for a device's MSI-X structure should be isolated so that the -software system can set different pages for controlling accesses to the -MSI-X structure. The implementation of MSI support requires the PCI -subsystem, not a device driver, to maintain full control of the MSI-X -table/MSI-X PBA (Pending Bit Array) and MMIO address space of the MSI-X -table/MSI-X PBA.

Depending on -the availability of PCI vectors resources, the PCI subsystem enables -either all or none of the requested vectors. - -Argument 'dev' points to the device (pci_dev) structure. - -Argument 'entries' is a pointer to an array of msix_entry structs. -The number of entries is indicated in argument 'nvec'. -struct msix_entry is defined in /driver/pci/msi.h: - -struct msix_entry { - u16 vector; /* kernel uses to write alloc vector */ - u16 entry; /* driver uses to specify entry */ -}; - -A device driver is responsible for initializing the field 'entry' of -each element with a unique entry supported by MSI-X table. Otherwise, --EINVAL will be returned as a result. A successful return of zero -indicates the PCI subsystem completed initializing each of the requested -entries of the MSI-X table with message address and message data. -Last but not least, the PCI subsystem will write the 1:1 -vector-to-entry mapping into the field 'vector' of each element. A -device driver is responsible for keeping track of allocated MSI-X -vectors in its internal data structure. - -A return of zero indicates that the number of MSI-X vectors was -successfully allocated. A return of greater than zero indicates -MSI-X vector shortage. Or a return of less than zero indicates -a failure. This failure may be a result of duplicate entries -specified in second argument, or a result of no available vector, -or a result of failing to initialize MSI-X table entries. - -5.3.3 API pci_disable_msix - -void pci_disable_msix(struct pci_dev *dev) - -This API should always be used to undo the effect of pci_enable_msix() -when a device driver is unloading. Note that a device driver should -always call free_irq() on all MSI-X vectors it has done request_irq() -on before calling this API. Failure to do so results in a BUG_ON() and -a device will be left with MSI-X enabled and leaks its vectors. - -5.3.4 MSI-X mode vs. legacy mode diagram - -The below diagram shows the events which switch the interrupt -mode on the MSI-X capable device function between MSI-X mode and -PIN-IRQ assertion mode (legacy). - - ------------ pci_enable_msix(,,n) ------------------------ - | | <=============== | | - | MSI-X MODE | | PIN-IRQ ASSERTION MODE | - | | ===============> | | - ------------ pci_disable_msix ------------------------ - -Figure 2. MSI-X Mode vs. Legacy Mode - -In Figure 2, a device operates by default in legacy mode. A -successful MSI-X request (using pci_enable_msix()) switches a -device's interrupt mode to MSI-X mode. A pre-assigned IOAPIC vector -stored in dev->irq will be saved by the PCI subsystem; however, -unlike MSI mode, the PCI subsystem will not replace dev->irq with -assigned MSI-X vector because the PCI subsystem already writes the 1:1 -vector-to-entry mapping into the field 'vector' of each element -specified in second argument. - -To return back to its default mode, a device driver should always call -pci_disable_msix() to undo the effect of pci_enable_msix(). Note that -a device driver should always call free_irq() on all MSI-X vectors it -has done request_irq() on before calling pci_disable_msix(). Failure -to do so results in a BUG_ON() and a device will be left with MSI-X -enabled and leaks its vectors.

Depending on -the availability of current PCI vector resources and the number of -MSI/MSI-X requests from other drivers, these MSI-X vectors may be -re-assigned. - -For the case where the PCI subsystem re-assigned these MSI-X vectors -to other drivers, a request to switch back to MSI-X mode may result -being assigned with another set of MSI-X vectors or a failure if no -more vectors are available. - -5.4 Handling function implementing both MSI and MSI-X capabilities - -For the case where a function implements both MSI and MSI-X -capabilities, the PCI subsystem enables a device to run either in MSI -mode or MSI-X mode but not both. A device driver determines whether it -wants MSI or MSI-X enabled on its hardware device. Once a device -driver requests for MSI, for example, it is prohibited from requesting -MSI-X; in other words, a device driver is not permitted to ping-pong -between MSI mod MSI-X mode during a run-time. - -5.5 Hardware requirements for MSI/MSI-X support - -MSI/MSI-X support requires support from both system hardware and -individual hardware device functions. - -5.5.1 Required x86 hardware support - -Since the target of MSI address is the local APIC CPU, enabling -MSI/MSI-X support in the Linux kernel is dependent on whether existing -system hardware supports local APIC. Users should verify that their -system supports local APIC operation by testing that it runs when -CONFIG_X86_LOCAL_APIC=y. - -In SMP environment, CONFIG_X86_LOCAL_APIC is automatically set; -however, in UP environment, users must manually set -CONFIG_X86_LOCAL_APIC. Once CONFIG_X86_LOCAL_APIC=y, setting -CONFIG_PCI_MSI enables the VECTOR based scheme and the option for -MSI-capable device drivers to selectively enable MSI/MSI-X. - -Note that CONFIG_X86_IO_APIC setting is irrelevant because MSI/MSI-X -vector is allocated new during runtime and MSI/MSI-X support does not -depend on BIOS support. This key independency enables MSI/MSI-X -support on future IOxAPIC free platforms. - -5.5.2 Device hardware support - -The hardware device function supports MSI by indicating the -MSI/MSI-X capability structure on its PCI capability list. By -default, this capability structure will not be initialized by -the kernel to enable MSI during the system boot. In other words, -the device function is running on its default pin assertion mode. -Note that in many cases the hardware supporting MSI have bugs, -which may result in system hangs. The software driver of specific -MSI-capable hardware is responsible for deciding whether to call -pci_enable_msi or not. A return of zero indicates the kernel -successfully initialized the MSI/MSI-X capability structure of the -device function. The device function is now running on MSI/MSI-X mode. - -5.6 How to tell whether MSI/MSI-X is enabled on device function - -At the driver level, a return of zero from the function call of -pci_enable_msi()/pci_enable_msix() indicates to a device driver that -its device function is initialized successfully and ready to run in -MSI/MSI-X mode. - -At the user level, users can use the command 'cat /proc/interrupts' -to display the vectors allocated for devices and their interrupt -MSI/MSI-X modes ("PCI-MSI"/"PCI-MSI-X").

MSI quirks - -Several PCI chipsets or devices are known to not support MSI. -The PCI stack provides 3 possible levels of MSI disabling: -* on a single device -* on all devices behind a specific bridge -* globally - -6.1. Disabling MSI on a single device - -Under some circumstances it might be required to disable MSI on a -single device. This may be achieved by either not calling pci_enable_msi() -or all, or setting the pci_dev->no_msi flag before (most of the time -in a quirk). - -6.2. Disabling MSI below a bridge - -The vast majority of MSI quirks are required by PCI bridges not -being able to route MSI between busses. In this case, MSI have to be -disabled on all devices behind this bridge. It is achieves by setting -the PCI_BUS_FLAGS_NO_MSI flag in the pci_bus->bus_flags of the bridge -subordinate bus. There is no need to set the same flag on bridges that -are below the broken bridge. When pci_enable_msi() is called to enable -MSI on a device, pci_msi_supported() takes care of checking the NO_MSI -flag in all parent busses of the device. - -Some bridges actually support dynamic MSI support enabling/disabling -by changing some bits in their PCI configuration space (especially -the Hypertransport chipsets such as the nVidia nForce and Serverworks -HT2000). It may then be required to update the NO_MSI flag on the -corresponding devices in the sysfs hierarchy. To enable MSI support -on device "0000:00:0e", do: - - echo 1 > /sys/bus/pci/devices/0000:00:0e/msi_bus - -To disable MSI support, echo 0 instead of 1. Note that it should be -used with caution since changing this value might break interrupts. - -6.3. Disabling MSI globally - -Some extreme cases may require to disable MSI globally on the system. -For now, the only known case is a Serverworks PCI-X chipsets (MSI are -not supported on several busses that are not all connected to the -chipset in the Linux PCI hierarchy). In the vast majority of other -cases, disabling only behind a specific bridge is enough. - -For debugging purpose, the user may also pass pci=nomsi on the kernel -command-line to explicitly disable MSI globally. But, once the appro- -priate quirks are added to the kernel, this option should not be -required anymore. - -6.4. Finding why MSI cannot be enabled on a device - -Assuming that MSI are not enabled on a device, you should look at -dmesg to find messages that quirks may output when disabling MSI -on some devices, some bridges or even globally. -Then, lspci -t gives the list of bridges above a device. Reading -/sys/bus/pci/devices/0000:00:0e/msi_bus will tell you whether MSI -are enabled (1) or disabled (0). In 0 is found in a single bridge -msi_bus file above the device, MSI cannot be enabled. - -7. FAQ - -Q1. Are there any limitations on using the MSI? - -A1. If the PCI device supports MSI and conforms to the -specification and the platform supports the APIC local bus, -then using MSI should work. - -Q2. Will it work on all the Pentium processors (P3, P4, Xeon, -AMD processors)? In P3 IPI's are transmitted on the APIC local -bus and in P4 and Xeon they are transmitted on the system -bus. Are there any implications with this? - -A2. MSI support enables a PCI device sending an inbound -memory write (0xfeexxxxx as target address) on its PCI bus -directly to the FSB. Since the message address has a -redirection hint bit cleared, it should work. - -Q3. The target address 0xfeexxxxx will be translated by the -Host Bridge into an interrupt message. Are there any -limitations on the chipsets such as Intel 8xx, Intel e7xxx, -or VIA? - -A3. If these chipsets support an inbound memory write with -target address set as 0xfeexxxxx, as conformed to PCI -specification 2.3 or latest, then it should work. - -Q4. From the driver point of view, if the MSI is lost because -of errors occurring during inbound memory write, then it may -wait forever. Is there a mechanism for it to recover? - -A4. Since the target of the transaction is an inbound memory -write, all transaction termination conditions (Retry, -Master-Abort, Target-Abort, or normal completion) are -supported. A device sending an MSI must abide by all the PCI -rules and conditions regarding that inbound memory write. So, -if a retry is signaled it must retry, etc... We believe that -the recommendation for Abort is also a retry (refer to PCI -specification 2.3 or latest). diff --git a/Documentation/PCI/00-INDEX b/Documentation/PCI/00-INDEX index 49f43946c6b..812b17fe3ed 100644 --- a/Documentation/PCI/00-INDEX +++ b/Documentation/PCI/00-INDEX @@ -1,5 +1,7 @@ 00-INDEX - this file +MSI-HOWTO.txt + - the Message Signaled Interrupts (MSI) Driver Guide HOWTO and FAQ.

There are +some key advantages to implementing the MSI-X capability structure +over the MSI capability structure as described below. + + - Support a larger maximum number of vectors per function. + + - Provide the ability for system software to configure + each vector with an independent message address and message + data, specified by a table that resides in Memory Space. + + - MSI and MSI-X both support per-vector masking. Per-vector + masking is an optional extension of MSI but a required + feature for MSI-X. Per-vector masking provides the kernel the + ability to mask/unmask a single MSI while running its + interrupt service routine. If per-vector masking is + not supported, then the device driver should provide the + hardware/software synchronization to ensure that the device + generates MSI when the driver wants it to do so. + +4. Why use MSI? + +As a benefit to the simplification of board design, MSI allows board +designers to remove out-of-band interrupt routing. MSI is another +step towards a legacy-free environment. + +Due to increasing pressure on chipset and processor packages to +reduce pin count, the need for interrupt pins is expected to +diminish over time. Devices, due to pin constraints, may implement +messages to increase performance. + +PCI Express endpoints uses INTx emulation (in-band messages) instead +of IRQ pin assertion. Using INTx emulation requires interrupt +sharing among devices connected to the same node (PCI bridge) while +MSI is unique (non-shared) and does not require BIOS configuration +support. As a result, the PCI Express technology requires MSI +support for better interrupt performance. + +Using MSI enables the device functions to support two or more +vectors, which can be configured to target different CPUs to +increase scalability. + +5. Configuring a driver to use MSI/MSI-X + +By default, the kernel will not enable MSI/MSI-X on all devices that +support this capability. The CONFIG_PCI_MSI kernel option +must be selected to enable MSI/MSI-X support. + +5.1 Including MSI/MSI-X support into the kernel + +To allow MSI/MSI-X capable device drivers to selectively enable +MSI/MSI-X (using pci_enable_msi()/pci_enable_msix() as described +below), the VECTOR based scheme needs to be enabled by setting +CONFIG_PCI_MSI during kernel config. + +Since the target of the inbound message is the local APIC, providing +CONFIG_X86_LOCAL_APIC must be enabled as well as CONFIG_PCI_MSI. + +5.2 Configuring for MSI support + +Due to the non-contiguous fashion in vector assignment of the +existing Linux kernel, this version does not support multiple +messages regardless of a device function is capable of supporting +more than one vector. To enable MSI on a device function's MSI +capability structure requires a device driver to call the function +pci_enable_msi() explicitly. + +5.2.1 API pci_enable_msi + +int pci_enable_msi(struct pci_dev *dev) + +With this new API, a device driver that wants to have MSI +enabled on its device function must call this API to enable MSI. +A successful call will initialize the MSI capability structure +with ONE vector, regardless of whether a device function is +capable of supporting multiple messages. This vector replaces the +pre-assigned dev->irq with a new MSI vector. To avoid a conflict +of the new assigned vector with existing pre-assigned vector requires +a device driver to call this API before calling request_irq(). + +5.2.2 API pci_disable_msi + +void pci_disable_msi(struct pci_dev *dev) + +This API should always be used to undo the effect of pci_enable_msi() +when a device driver is unloading. This API restores dev->irq with +the pre-assigned IOAPIC vector and switches a device's interrupt +mode to PCI pin-irq assertion/INTx emulation mode. + +Note that a device driver should always call free_irq() on the MSI vector +that it has done request_irq() on before calling this API. Failure to do +so results in a BUG_ON() and a device will be left with MSI enabled and +leaks its vector. + +5.2.3 MSI mode vs. legacy mode diagram + +The below diagram shows the events which switch the interrupt +mode on the MSI-capable device function between MSI mode and +PIN-IRQ assertion mode. + + ------------ pci_enable_msi ------------------------ + | | <=============== | | + | MSI MODE | | PIN-IRQ ASSERTION MODE | + | | ===============> | | + ------------ pci_disable_msi ------------------------ + + +Figure 1. MSI Mode vs. Legacy Mode + +In Figure 1, a device operates by default in legacy mode. Legacy +in this context means PCI pin-irq assertion or PCI-Express INTx +emulation. A successful MSI request (using pci_enable_msi()) switches +a device's interrupt mode to MSI mode. A pre-assigned IOAPIC vector +stored in dev->irq will be saved by the PCI subsystem and a new +assigned MSI vector will replace dev->irq. + +To return back to its default mode, a device driver should always call +pci_disable_msi() to undo the effect of pci_enable_msi(). Note that a +device driver should always call free_irq() on the MSI vector it has +done request_irq() on before calling pci_disable_msi(). Failure to do +so results in a BUG_ON() and a device will be left with MSI enabled and +leaks its vector. Otherwise, the PCI subsystem restores a device's +dev->irq with a pre-assigned IOAPIC vector and marks the released +MSI vector as unused. + +Once being marked as unused, there is no guarantee that the PCI +subsystem will reserve this MSI vector for a device. Depending on +the availability of current PCI vector resources and the number of +MSI/MSI-X requests from other drivers, this MSI may be re-assigned. + +For the case where the PCI subsystem re-assigns this MSI vector to +another driver, a request to switch back to MSI mode may result +in being assigned a different MSI vector or a failure if no more +vectors are available. + +5.3 Configuring for MSI-X support + +Due to the ability of the system software to configure each vector of +the MSI-X capability structure with an independent message address +and message data, the non-contiguous fashion in vector assignment of +the existing Linux kernel has no impact on supporting multiple +messages on an MSI-X capable device functions. To enable MSI-X on +a device function's MSI-X capability structure requires its device +driver to call the function pci_enable_msix() explicitly. + +The function pci_enable_msix(), once invoked, enables either +all or nothing, depending on the current availability of PCI vector +resources. If the PCI vector resources are available for the number +of vectors requested by a device driver, this function will configure +the MSI-X table of the MSI-X capability structure of a device with +requested messages. To emphasize this reason, for example, a device +may be capable for supporting the maximum of 32 vectors while its +software driver usually may request 4 vectors. It is recommended +that the device driver should call this function once during the +initialization phase of the device driver. + +Unlike the function pci_enable_msi(), the function pci_enable_msix() +does not replace the pre-assigned IOAPIC dev->irq with a new MSI +vector because the PCI subsystem writes the 1:1 vector-to-entry mapping +into the field vector of each element contained in a second argument. +Note that the pre-assigned IOAPIC dev->irq is valid only if the device +operates in PIN-IRQ assertion mode. In MSI-X mode, any attempt at +using dev->irq by the device driver to request for interrupt service +may result in unpredictable behavior. + +For each MSI-X vector granted, a device driver is responsible for calling +other functions like request_irq(), enable_irq(), etc. to enable +this vector with its corresponding interrupt service handler. It is +a device driver's choice to assign all vectors with the same +interrupt service handler or each vector with a unique interrupt +service handler. + +5.3.1 Handling MMIO address space of MSI-X Table + +The PCI 3.0 specification has implementation notes that MMIO address +space for a device's MSI-X structure should be isolated so that the +software system can set different pages for controlling accesses to the +MSI-X structure. The implementation of MSI support requires the PCI +subsystem, not a device driver, to maintain full control of the MSI-X +table/MSI-X PBA (Pending Bit Array) and MMIO address space of the MSI-X +table/MSI-X PBA. A device driver should not access the MMIO address +space of the MSI-X table/MSI-X PBA. + +5.3.2 API pci_enable_msix + +int pci_enable_msix(struct pci_dev *dev, struct msix_entry *entries, int nvec) + +This API enables a device driver to request the PCI subsystem +to enable MSI-X messages on its hardware device. Depending on +the availability of PCI vectors resources, the PCI subsystem enables +either all or none of the requested vectors. + +Argument 'dev' points to the device (pci_dev) structure. + +Argument 'entries' is a pointer to an array of msix_entry structs. +The number of entries is indicated in argument 'nvec'. +struct msix_entry is defined in /driver/pci/msi.h: + +struct msix_entry { + u16 vector; /* kernel uses to write alloc vector */ + u16 entry; /* driver uses to specify entry */ +}; + +A device driver is responsible for initializing the field 'entry' of +each element with a unique entry supported by MSI-X table. Otherwise, +-EINVAL will be returned as a result. A successful return of zero +indicates the PCI subsystem completed initializing each of the requested +entries of the MSI-X table with message address and message data. +Last but not least, the PCI subsystem will write the 1:1 +vector-to-entry mapping into the field 'vector' of each element. A +device driver is responsible for keeping track of allocated MSI-X +vectors in its internal data structure. + +A return of zero indicates that the number of MSI-X vectors was +successfully allocated. A return of greater than zero indicates +MSI-X vector shortage. Or a return of less than zero indicates +a failure. This failure may be a result of duplicate entries +specified in second argument, or a result of no available vector, +or a result of failing to initialize MSI-X table entries. + +5.3.3 API pci_disable_msix + +void pci_disable_msix(struct pci_dev *dev) + +This API should always be used to undo the effect of pci_enable_msix() +when a device driver is unloading. Note that a device driver should +always call free_irq() on all MSI-X vectors it has done request_irq() +on before calling this API. Failure to do so results in a BUG_ON() and +a device will be left with MSI-X enabled and leaks its vectors. + +5.3.4 MSI-X mode vs. legacy mode diagram + +The below diagram shows the events which switch the interrupt +mode on the MSI-X capable device function between MSI-X mode and +PIN-IRQ assertion mode (legacy). + + ------------ pci_enable_msix(,,n) ------------------------ + | | <=============== | | + | MSI-X MODE | | PIN-IRQ ASSERTION MODE | + | | ===============> | | + ------------ pci_disable_msix ------------------------ + +Figure 2. MSI-X Mode vs. Legacy Mode + +In Figure 2, a device operates by default in legacy mode. A +successful MSI-X request (using pci_enable_msix()) switches a +device's interrupt mode to MSI-X mode. A pre-assigned IOAPIC vector +stored in dev->irq will be saved by the PCI subsystem; however, +unlike MSI mode, the PCI subsystem will not replace dev->irq with +assigned MSI-X vector because the PCI subsystem already writes the 1:1 +vector-to-entry mapping into the field 'vector' of each element +specified in second argument. + +To return back to its default mode, a device driver should always call +pci_disable_msix() to undo the effect of pci_enable_msix(). Note that +a device driver should always call free_irq() on all MSI-X vectors it +has done request_irq() on before calling pci_disable_msix(). Failure +to do so results in a BUG_ON() and a device will be left with MSI-X +enabled and leaks its vectors. Otherwise, the PCI subsystem switches a +device function's interrupt mode from MSI-X mode to legacy mode and +marks all allocated MSI-X vectors as unused. + +Once being marked as unused, there is no guarantee that the PCI +subsystem will reserve these MSI-X vectors for a device. Depending on +the availability of current PCI vector resources and the number of +MSI/MSI-X requests from other drivers, these MSI-X vectors may be +re-assigned. + +For the case where the PCI subsystem re-assigned these MSI-X vectors +to other drivers, a request to switch back to MSI-X mode may result +being assigned with another set of MSI-X vectors or a failure if no +more vectors are available. + +5.4 Handling function implementing both MSI and MSI-X capabilities + +For the case where a function implements both MSI and MSI-X +capabilities, the PCI subsystem enables a device to run either in MSI +mode or MSI-X mode but not both. A device driver determines whether it +wants MSI or MSI-X enabled on its hardware device. Once a device +driver requests for MSI, for example, it is prohibited from requesting +MSI-X; in other words, a device driver is not permitted to ping-pong +between MSI mod MSI-X mode during a run-time. + +5.5 Hardware requirements for MSI/MSI-X support + +MSI/MSI-X support requires support from both system hardware and +individual hardware device functions. + +5.5.1 Required x86 hardware support + +Since the target of MSI address is the local APIC CPU, enabling +MSI/MSI-X support in the Linux kernel is dependent on whether existing +system hardware supports local APIC. Users should verify that their +system supports local APIC operation by testing that it runs when +CONFIG_X86_LOCAL_APIC=y. + +In SMP environment, CONFIG_X86_LOCAL_APIC is automatically set; +however, in UP environment, users must manually set +CONFIG_X86_LOCAL_APIC. Once CONFIG_X86_LOCAL_APIC=y, setting +CONFIG_PCI_MSI enables the VECTOR based scheme and the option for +MSI-capable device drivers to selectively enable MSI/MSI-X. + +Note that CONFIG_X86_IO_APIC setting is irrelevant because MSI/MSI-X +vector is allocated new during runtime and MSI/MSI-X support does not +depend on BIOS support. This key independency enables MSI/MSI-X +support on future IOxAPIC free platforms. + +5.5.2 Device hardware support + +The hardware device function supports MSI by indicating the +MSI/MSI-X capability structure on its PCI capability list. By +default, this capability structure will not be initialized by +the kernel to enable MSI during the system boot. In other words, +the device function is running on its default pin assertion mode. +Note that in many cases the hardware supporting MSI have bugs, +which may result in system hangs. The software driver of specific +MSI-capable hardware is responsible for deciding whether to call +pci_enable_msi or not. A return of zero indicates the kernel +successfully initialized the MSI/MSI-X capability structure of the +device function. The device function is now running on MSI/MSI-X mode. + +5.6 How to tell whether MSI/MSI-X is enabled on device function + +At the driver level, a return of zero from the function call of +pci_enable_msi()/pci_enable_msix() indicates to a device driver that +its device function is initialized successfully and ready to run in +MSI/MSI-X mode. + +At the user level, users can use the command 'cat /proc/interrupts' +to display the vectors allocated for devices and their interrupt +MSI/MSI-X modes ("PCI-MSI"/"PCI-MSI-X"). Below shows MSI mode is +enabled on a SCSI Adaptec 39320D Ultra320 controller. + + CPU0 CPU1 + 0: 324639 0 IO-APIC-edge timer + 1: 1186 0 IO-APIC-edge i8042 + 2: 0 0 XT-PIC cascade + 12: 2797 0 IO-APIC-edge i8042 + 14: 6543 0 IO-APIC-edge ide0 + 15: 1 0 IO-APIC-edge ide1 +169: 0 0 IO-APIC-level uhci-hcd +185: 0 0 IO-APIC-level uhci-hcd +193: 138 10 PCI-MSI aic79xx +201: 30 0 PCI-MSI aic79xx +225: 30 0 IO-APIC-level aic7xxx +233: 30 0 IO-APIC-level aic7xxx +NMI: 0 0 +LOC: 324553 325068 +ERR: 0 +MIS: 0 + +6. MSI quirks + +Several PCI chipsets or devices are known to not support MSI. +The PCI stack provides 3 possible levels of MSI disabling: +* on a single device +* on all devices behind a specific bridge +* globally + +6.1. Disabling MSI on a single device + +Under some circumstances it might be required to disable MSI on a +single device. This may be achieved by either not calling pci_enable_msi() +or all, or setting the pci_dev->no_msi flag before (most of the time +in a quirk). + +6.2. Disabling MSI below a bridge + +The vast majority of MSI quirks are required by PCI bridges not +being able to route MSI between busses. In this case, MSI have to be +disabled on all devices behind this bridge. It is achieves by setting +the PCI_BUS_FLAGS_NO_MSI flag in the pci_bus->bus_flags of the bridge +subordinate bus. There is no need to set the same flag on bridges that +are below the broken bridge. When pci_enable_msi() is called to enable +MSI on a device, pci_msi_supported() takes care of checking the NO_MSI +flag in all parent busses of the device. + +Some bridges actually support dynamic MSI support enabling/disabling +by changing some bits in their PCI configuration space (especially +the Hypertransport chipsets such as the nVidia nForce and Serverworks +HT2000). It may then be required to update the NO_MSI flag on the +corresponding devices in the sysfs hierarchy. To enable MSI support +on device "0000:00:0e", do: + + echo 1 > /sys/bus/pci/devices/0000:00:0e/msi_bus + +To disable MSI support, echo 0 instead of 1. Note that it should be +used with caution since changing this value might break interrupts. + +6.3. Disabling MSI globally + +Some extreme cases may require to disable MSI globally on the system. +For now, the only known case is a Serverworks PCI-X chipsets (MSI are +not supported on several busses that are not all connected to the +chipset in the Linux PCI hierarchy). In the vast majority of other +cases, disabling only behind a specific bridge is enough. + +For debugging purpose, the user may also pass pci=nomsi on the kernel +command-line to explicitly disable MSI globally. But, once the appro- +priate quirks are added to the kernel, this option should not be +required anymore. + +6.4. Finding why MSI cannot be enabled on a device + +Assuming that MSI are not enabled on a device, you should look at +dmesg to find messages that quirks may output when disabling MSI +on some devices, some bridges or even globally. +Then, lspci -t gives the list of bridges above a device. Reading +/sys/bus/pci/devices/0000:00:0e/msi_bus will tell you whether MSI +are enabled (1) or disabled (0). In 0 is found in a single bridge +msi_bus file above the device, MSI cannot be enabled. + +7. FAQ + +Q1. Are there any limitations on using the MSI? + +A1. If the PCI device supports MSI and conforms to the +specification and the platform supports the APIC local bus, +then using MSI should work. + +Q2. Will it work on all the Pentium processors (P3, P4, Xeon, +AMD processors)? In P3 IPI's are transmitted on the APIC local +bus and in P4 and Xeon they are transmitted on the system +bus. Are there any implications with this? + +A2. MSI support enables a PCI device sending an inbound +memory write (0xfeexxxxx as target address) on its PCI bus +directly to the FSB. Since the message address has a +redirection hint bit cleared, it should work. + +Q3. The target address 0xfeexxxxx will be translated by the +Host Bridge into an interrupt message. Are there any +limitations on the chipsets such as Intel 8xx, Intel e7xxx, +or VIA? + +A3. If these chipsets support an inbound memory write with +target address set as 0xfeexxxxx, as conformed to PCI +specification 2.3 or latest, then it should work. + +Q4. From the driver point of view, if the MSI is lost because +of errors occurring during inbound memory write, then it may +wait forever. Is there a mechanism for it to recover? + +A4. Since the target of the transaction is an inbound memory +write, all transaction termination conditions (Retry, +Master-Abort, Target-Abort, or normal completion) are +supported. A device sending an MSI must abide by all the PCI +rules and conditions regarding that inbound memory write. So, +if a retry is signaled it must retry, etc... We believe that +the recommendation for Abort is also a retry (refer to PCI +specification 2.3 or latest). diff --git a/Documentation/README.DAC960 b/Documentation/README.DAC960 deleted file mode 100644 index 0e8f618ab53..00000000000 --- a/Documentation/README.DAC960 +++ /dev/null @@ -1,756 +0,0 @@ - Linux Driver for Mylex DAC960/AcceleRAID/eXtremeRAID PCI RAID Controllers - - Version 2.2.11 for Linux 2.2.19 - Version 2.4.11 for Linux 2.4.12 - - PRODUCTION RELEASE - - 11 October 2001 - - Leonard N.

Contact information for offices in Europe and Japan is available -on their Web site. - -The latest information on Linux support for DAC960 PCI RAID Controllers, as -well as the most recent release of this driver, will always be available from -my Linux Home Page at URL "http://www.dandelion.com/Linux/". The Linux DAC960 -driver supports all current Mylex PCI RAID controllers including the new -eXtremeRAID 2000/3000 and AcceleRAID 352/170/160 models which have an entirely -new firmware interface from the older eXtremeRAID 1100, AcceleRAID 150/200/250, -and DAC960PJ/PG/PU/PD/PL. See below for a complete controller list as well as -minimum firmware version requirements. For simplicity, in most places this -documentation refers to DAC960 generically rather than explicitly listing all -the supported models. - -Driver bug reports should be sent via electronic mail to "lnz@dandelion.com". -Please include with the bug report the complete configuration messages reported -by the driver at startup, along with any subsequent system messages relevant to -the controller's operation, and a detailed description of your system's -hardware configuration. Driver bugs are actually quite rare; if you encounter -problems with disks being marked offline, for example, please contact Mylex -Technical Support as the problem is related to the hardware configuration -rather than the Linux driver. - -Please consult the RAID controller documentation for detailed information -regarding installation and configuration of the controllers. This document -primarily provides information specific to the Linux support. - - - DRIVER FEATURES - -The DAC960 RAID controllers are supported solely as high performance RAID -controllers, not as interfaces to arbitrary SCSI devices. The Linux DAC960 -driver operates at the block device level, the same level as the SCSI and IDE -drivers. Unlike other RAID controllers currently supported on Linux, the -DAC960 driver is not dependent on the SCSI subsystem, and hence avoids all the -complexity and unnecessary code that would be associated with an implementation -as a SCSI driver. The DAC960 driver is designed for as high a performance as -possible with no compromises or extra code for compatibility with lower -performance devices. The DAC960 driver includes extensive error logging and -online configuration management capabilities. Except for initial configuration -of the controller and adding new disk drives, most everything can be handled -from Linux while the system is operational. - -The DAC960 driver is architected to support up to 8 controllers per system. -Each DAC960 parallel SCSI controller can support up to 15 disk drives per -channel, for a maximum of 60 drives on a four channel controller; the fibre -channel eXtremeRAID 3000 controller supports up to 125 disk drives per loop for -a total of 250 drives. The drives installed on a controller are divided into -one or more "Drive Groups", and then each Drive Group is subdivided further -into 1 to 32 "Logical Drives". Each Logical Drive has a specific RAID Level -and caching policy associated with it, and it appears to Linux as a single -block device. Logical Drives are further subdivided into up to 7 partitions -through the normal Linux and PC disk partitioning schemes. Logical Drives are -also known as "System Drives", and Drive Groups are also called "Packs". Both -terms are in use in the Mylex documentation; I have chosen to standardize on -the more generic "Logical Drive" and "Drive Group". - -DAC960 RAID disk devices are named in the style of the obsolete Device File -System (DEVFS). The device corresponding to Logical Drive D on Controller C -is referred to as /dev/rd/cCdD, and the partitions are called /dev/rd/cCdDp1 -through /dev/rd/cCdDp7. For example, partition 3 of Logical Drive 5 on -Controller 2 is referred to as /dev/rd/c2d5p3. Note that unlike with SCSI -disks the device names will not change in the event of a disk drive failure. -The DAC960 driver is assigned major numbers 48 - 55 with one major number per -controller. The 8 bits of minor number are divided into 5 bits for the Logical -Drive and 3 bits for the partition. - - - SUPPORTED DAC960/AcceleRAID/eXtremeRAID PCI RAID CONTROLLERS - -The following list comprises the supported DAC960, AcceleRAID, and eXtremeRAID -PCI RAID Controllers as of the date of this document.

Mylex makes available a hard disk compatibility list at -http://www.mylex.com/support/hdcomp/hd-lists.html. - - - DRIVER INSTALLATION - -This distribution was prepared for Linux kernel version 2.2.19 or 2.4.12. - -To install the DAC960 RAID driver, you may use the following commands, -replacing "/usr/src" with wherever you keep your Linux kernel source tree: - - cd /usr/src - tar -xvzf DAC960-2.2.11.tar.gz (or DAC960-2.4.11.tar.gz) - mv README.DAC960 linux/Documentation - mv DAC960.[ch] linux/drivers/block - patch -p0 < DAC960.patch (if DAC960.patch is included) - cd linux - make config - make bzImage (or zImage) - -Then install "arch/i386/boot/bzImage" or "arch/i386/boot/zImage" as your -standard kernel, run lilo if appropriate, and reboot. - -To create the necessary devices in /dev, the "make_rd" script included in -"DAC960-Utilities.tar.gz" from http://www.dandelion.com/Linux/ may be used. -LILO 21 and FDISK v2.9 include DAC960 support; also included in this archive -are patches to LILO 20 and FDISK v2.8 that add DAC960 support, along with -statically linked executables of LILO and FDISK. This modified version of LILO -will allow booting from a DAC960 controller and/or mounting the root file -system from a DAC960. - -Red Hat Linux 6.0 and SuSE Linux 6.1 include support for Mylex PCI RAID -controllers. Installing directly onto a DAC960 may be problematic from other -Linux distributions until their installation utilities are updated. - - - INSTALLATION NOTES - -Before installing Linux or adding DAC960 logical drives to an existing Linux -system, the controller must first be configured to provide one or more logical -drives using the BIOS Configuration Utility or DACCF. Please note that since -there are only at most 6 usable partitions on each logical drive, systems -requiring more partitions should subdivide a drive group into multiple logical -drives, each of which can have up to 6 usable partitions. Also, note that with -large disk arrays it is advisable to enable the 8GB BIOS Geometry (255/63) -rather than accepting the default 2GB BIOS Geometry (128/32); failing to so do -will cause the logical drive geometry to have more than 65535 cylinders which -will make it impossible for FDISK to be used properly. The 8GB BIOS Geometry -can be enabled by configuring the DAC960 BIOS, which is accessible via Alt-M -during the BIOS initialization sequence. - -For maximum performance and the most efficient E2FSCK performance, it is -recommended that EXT2 file systems be built with a 4KB block size and 16 block -stride to match the DAC960 controller's 64KB default stripe size. The command -"mke2fs -b 4096 -R stride=16 " is appropriate. Unless there will be a -large number of small files on the file systems, it is also beneficial to add -the "-i 16384" option to increase the bytes per inode parameter thereby -reducing the file system metadata. Finally, on systems that will only be run -with Linux 2.2 or later kernels it is beneficial to enable sparse superblocks -with the "-s 1" option. - - - DAC960 ANNOUNCEMENTS MAILING LIST - -The DAC960 Announcements Mailing List provides a forum for informing Linux -users of new driver releases and other announcements regarding Linux support -for DAC960 PCI RAID Controllers. To join the mailing list, send a message to -"dac960-announce-request@dandelion.com" with the line "subscribe" in the -message body. - - - CONTROLLER CONFIGURATION AND STATUS MONITORING - -The DAC960 RAID controllers running firmware 4.06 or above include a Background -Initialization facility so that system downtime is minimized both for initial -installation and subsequent configuration of additional storage. The BIOS -Configuration Utility (accessible via Alt-R during the BIOS initialization -sequence) is used to quickly configure the controller, and then the logical -drives that have been created are available for immediate use even while they -are still being initialized by the controller. The primary need for online -configuration and status monitoring is then to avoid system downtime when disk -drives fail and must be replaced. Mylex's online monitoring and configuration -utilities are being ported to Linux and will become available at some point in -the future. Note that with a SAF-TE (SCSI Accessed Fault-Tolerant Enclosure) -enclosure, the controller is able to rebuild failed drives automatically as -soon as a drive replacement is made available. - -The primary interfaces for controller configuration and status monitoring are -special files created in the /proc/rd/... hierarchy along with the normal -system console logging mechanism. Whenever the system is operating, the DAC960 -driver queries each controller for status information every 10 seconds, and -checks for additional conditions every 60 seconds. The initial status of each -controller is always available for controller N in /proc/rd/cN/initial_status, -and the current status as of the last status monitoring query is available in -/proc/rd/cN/current_status. In addition, status changes are also logged by the -driver to the system console and will appear in the log files maintained by -syslog. The progress of asynchronous rebuild or consistency check operations -is also available in /proc/rd/cN/current_status, and progress messages are -logged to the system console at most every 60 seconds. - -Starting with the 2.2.3/2.0.3 versions of the driver, the status information -available in /proc/rd/cN/initial_status and /proc/rd/cN/current_status has been -augmented to include the vendor, model, revision, and serial number (if -available) for each physical device found connected to the controller: - -***** DAC960 RAID Driver Version 2.2.3 of 19 August 1999 ***** -Copyright 1998-1999 by Leonard N.

A human readable command can be written to this -special file to initiate a configuration operation, and the results of the -operation can then be read back from the special file in addition to being -logged to the system console. The shell command sequence - - echo "" > /proc/rd/c0/user_command - cat /proc/rd/c0/user_command - -is typically used to execute configuration commands. The configuration -commands are: - - flush-cache - - The "flush-cache" command flushes the controller's cache. The system - automatically flushes the cache at shutdown or if the driver module is - unloaded, so this command is only needed to be certain a write back cache - is flushed to disk before the system is powered off by a command to a UPS. - Note that the flush-cache command also stops an asynchronous rebuild or - consistency check, so it should not be used except when the system is being - halted. - - kill : - - The "kill" command marks the physical drive : as DEAD. - This command is provided primarily for testing, and should not be used - during normal system operation. - - make-online : - - The "make-online" command changes the physical drive : - from status DEAD to status ONLINE. In cases where multiple physical drives - have been killed simultaneously, this command may be used to bring all but - one of them back online, after which a rebuild to the final drive is - necessary. - - Warning: make-online should only be used on a dead physical drive that is - an active part of a drive group, never on a standby drive. The command - should never be used on a dead drive that is part of a critical logical - drive; rebuild should be used if only a single drive is dead. - - make-standby : - - The "make-standby" command changes physical drive : - from status DEAD to status STANDBY. It should only be used in cases where - a dead drive was replaced after an automatic rebuild was performed onto a - standby drive. It cannot be used to add a standby drive to the controller - configuration if one was not created initially; the BIOS Configuration - Utility must be used for that currently. - - rebuild : - - The "rebuild" command initiates an asynchronous rebuild onto physical drive - :. It should only be used when a dead drive has been - replaced. - - check-consistency - - The "check-consistency" command initiates an asynchronous consistency check - of with automatic restoration. It can be used - whenever it is desired to verify the consistency of the redundancy - information. - - cancel-rebuild - cancel-consistency-check - - The "cancel-rebuild" and "cancel-consistency-check" commands cancel any - rebuild or consistency check operations previously initiated. - - - EXAMPLE I - DRIVE FAILURE WITHOUT A STANDBY DRIVE - -The following annotated logs demonstrate the controller configuration and and -online status monitoring capabilities of the Linux DAC960 Driver.

Zubkoff + Dandelion Digital + lnz@dandelion.com + + Copyright 1998-2001 by Leonard N. Zubkoff + + + INTRODUCTION + +Mylex, Inc. designs and manufactures a variety of high performance PCI RAID +controllers. Mylex Corporation is located at 34551 Ardenwood Blvd., Fremont, +California 94555, USA and can be reached at 510.796.6100 or on the World Wide +Web at http://www.mylex.com. Mylex Technical Support can be reached by +electronic mail at mylexsup@us.ibm.com, by voice at 510.608.2400, or by FAX at +510.745.7715. Contact information for offices in Europe and Japan is available +on their Web site. + +The latest information on Linux support for DAC960 PCI RAID Controllers, as +well as the most recent release of this driver, will always be available from +my Linux Home Page at URL "http://www.dandelion.com/Linux/". The Linux DAC960 +driver supports all current Mylex PCI RAID controllers including the new +eXtremeRAID 2000/3000 and AcceleRAID 352/170/160 models which have an entirely +new firmware interface from the older eXtremeRAID 1100, AcceleRAID 150/200/250, +and DAC960PJ/PG/PU/PD/PL. See below for a complete controller list as well as +minimum firmware version requirements. For simplicity, in most places this +documentation refers to DAC960 generically rather than explicitly listing all +the supported models. + +Driver bug reports should be sent via electronic mail to "lnz@dandelion.com". +Please include with the bug report the complete configuration messages reported +by the driver at startup, along with any subsequent system messages relevant to +the controller's operation, and a detailed description of your system's +hardware configuration. Driver bugs are actually quite rare; if you encounter +problems with disks being marked offline, for example, please contact Mylex +Technical Support as the problem is related to the hardware configuration +rather than the Linux driver. + +Please consult the RAID controller documentation for detailed information +regarding installation and configuration of the controllers. This document +primarily provides information specific to the Linux support. + + + DRIVER FEATURES + +The DAC960 RAID controllers are supported solely as high performance RAID +controllers, not as interfaces to arbitrary SCSI devices. The Linux DAC960 +driver operates at the block device level, the same level as the SCSI and IDE +drivers. Unlike other RAID controllers currently supported on Linux, the +DAC960 driver is not dependent on the SCSI subsystem, and hence avoids all the +complexity and unnecessary code that would be associated with an implementation +as a SCSI driver. The DAC960 driver is designed for as high a performance as +possible with no compromises or extra code for compatibility with lower +performance devices. The DAC960 driver includes extensive error logging and +online configuration management capabilities. Except for initial configuration +of the controller and adding new disk drives, most everything can be handled +from Linux while the system is operational. + +The DAC960 driver is architected to support up to 8 controllers per system. +Each DAC960 parallel SCSI controller can support up to 15 disk drives per +channel, for a maximum of 60 drives on a four channel controller; the fibre +channel eXtremeRAID 3000 controller supports up to 125 disk drives per loop for +a total of 250 drives. The drives installed on a controller are divided into +one or more "Drive Groups", and then each Drive Group is subdivided further +into 1 to 32 "Logical Drives". Each Logical Drive has a specific RAID Level +and caching policy associated with it, and it appears to Linux as a single +block device. Logical Drives are further subdivided into up to 7 partitions +through the normal Linux and PC disk partitioning schemes. Logical Drives are +also known as "System Drives", and Drive Groups are also called "Packs". Both +terms are in use in the Mylex documentation; I have chosen to standardize on +the more generic "Logical Drive" and "Drive Group". + +DAC960 RAID disk devices are named in the style of the obsolete Device File +System (DEVFS). The device corresponding to Logical Drive D on Controller C +is referred to as /dev/rd/cCdD, and the partitions are called /dev/rd/cCdDp1 +through /dev/rd/cCdDp7. For example, partition 3 of Logical Drive 5 on +Controller 2 is referred to as /dev/rd/c2d5p3. Note that unlike with SCSI +disks the device names will not change in the event of a disk drive failure. +The DAC960 driver is assigned major numbers 48 - 55 with one major number per +controller. The 8 bits of minor number are divided into 5 bits for the Logical +Drive and 3 bits for the partition. + + + SUPPORTED DAC960/AcceleRAID/eXtremeRAID PCI RAID CONTROLLERS + +The following list comprises the supported DAC960, AcceleRAID, and eXtremeRAID +PCI RAID Controllers as of the date of this document.

This modified version of LILO +will allow booting from a DAC960 controller and/or mounting the root file +system from a DAC960. + +Red Hat Linux 6.0 and SuSE Linux 6.1 include support for Mylex PCI RAID +controllers. Installing directly onto a DAC960 may be problematic from other +Linux distributions until their installation utilities are updated. + + + INSTALLATION NOTES + +Before installing Linux or adding DAC960 logical drives to an existing Linux +system, the controller must first be configured to provide one or more logical +drives using the BIOS Configuration Utility or DACCF. Please note that since +there are only at most 6 usable partitions on each logical drive, systems +requiring more partitions should subdivide a drive group into multiple logical +drives, each of which can have up to 6 usable partitions. Also, note that with +large disk arrays it is advisable to enable the 8GB BIOS Geometry (255/63) +rather than accepting the default 2GB BIOS Geometry (128/32); failing to so do +will cause the logical drive geometry to have more than 65535 cylinders which +will make it impossible for FDISK to be used properly. The 8GB BIOS Geometry +can be enabled by configuring the DAC960 BIOS, which is accessible via Alt-M +during the BIOS initialization sequence. + +For maximum performance and the most efficient E2FSCK performance, it is +recommended that EXT2 file systems be built with a 4KB block size and 16 block +stride to match the DAC960 controller's 64KB default stripe size. The command +"mke2fs -b 4096 -R stride=16 " is appropriate. Unless there will be a +large number of small files on the file systems, it is also beneficial to add +the "-i 16384" option to increase the bytes per inode parameter thereby +reducing the file system metadata. Finally, on systems that will only be run +with Linux 2.2 or later kernels it is beneficial to enable sparse superblocks +with the "-s 1" option. + + + DAC960 ANNOUNCEMENTS MAILING LIST + +The DAC960 Announcements Mailing List provides a forum for informing Linux +users of new driver releases and other announcements regarding Linux support +for DAC960 PCI RAID Controllers. To join the mailing list, send a message to +"dac960-announce-request@dandelion.com" with the line "subscribe" in the +message body. + + + CONTROLLER CONFIGURATION AND STATUS MONITORING + +The DAC960 RAID controllers running firmware 4.06 or above include a Background +Initialization facility so that system downtime is minimized both for initial +installation and subsequent configuration of additional storage. The BIOS +Configuration Utility (accessible via Alt-R during the BIOS initialization +sequence) is used to quickly configure the controller, and then the logical +drives that have been created are available for immediate use even while they +are still being initialized by the controller. The primary need for online +configuration and status monitoring is then to avoid system downtime when disk +drives fail and must be replaced. Mylex's online monitoring and configuration +utilities are being ported to Linux and will become available at some point in +the future. Note that with a SAF-TE (SCSI Accessed Fault-Tolerant Enclosure) +enclosure, the controller is able to rebuild failed drives automatically as +soon as a drive replacement is made available. + +The primary interfaces for controller configuration and status monitoring are +special files created in the /proc/rd/... hierarchy along with the normal +system console logging mechanism. Whenever the system is operating, the DAC960 +driver queries each controller for status information every 10 seconds, and +checks for additional conditions every 60 seconds. The initial status of each +controller is always available for controller N in /proc/rd/cN/initial_status, +and the current status as of the last status monitoring query is available in +/proc/rd/cN/current_status. In addition, status changes are also logged by the +driver to the system console and will appear in the log files maintained by +syslog. The progress of asynchronous rebuild or consistency check operations +is also available in /proc/rd/cN/current_status, and progress messages are +logged to the system console at most every 60 seconds. + +Starting with the 2.2.3/2.0.3 versions of the driver, the status information +available in /proc/rd/cN/initial_status and /proc/rd/cN/current_status has been +augmented to include the vendor, model, revision, and serial number (if +available) for each physical device found connected to the controller: + +***** DAC960 RAID Driver Version 2.2.3 of 19 August 1999 ***** +Copyright 1998-1999 by Leonard N.

(e.g. +/dev/st0, /dev/st1, etc. See the "st" man page for more details.) +You must enable "SCSI tape drive support for Smart Array 5xxx" and +"SCSI support" in your kernel configuration to be able to use SCSI +tape drives with your Smart Array 5xxx controller. + +Additionally, note that the driver will not engage the SCSI core at init +time. The driver must be directed to dynamically engage the SCSI core via +the /proc filesystem entry which the "block" side of the driver creates as +/proc/driver/cciss/cciss* at runtime. This is because at driver init time, +the SCSI core may not yet be initialized (because the driver is a block +driver) and attempting to register it with the SCSI core in such a case +would cause a hang. This is best done via an initialization script +(typically in /etc/init.d, but could vary depending on distribution). +For example: + + for x in /proc/driver/cciss/cciss[0-9]* + do + echo "engage scsi" > $x + done + +Once the SCSI core is engaged by the driver, it cannot be disengaged +(except by unloading the driver, if it happens to be linked as a module.) + +Note also that if no sequential access devices or medium changers are +detected, the SCSI core will not be engaged by the action of the above +script. + +Hot plug support for SCSI tape drives +------------------------------------- + +Hot plugging of SCSI tape drives is supported, with some caveats. +The cciss driver must be informed that changes to the SCSI bus +have been made. This may be done via the /proc filesystem. +For example: + + echo "rescan" > /proc/scsi/cciss0/1 + +This causes the driver to query the adapter about changes to the +physical SCSI buses and/or fibre channel arbitrated loop and the +driver to make note of any new or removed sequential access devices +or medium changers. The driver will output messages indicating what +devices have been added or removed and the controller, bus, target and +lun used to address the device. It then notifies the SCSI mid layer +of these changes. + +Note that the naming convention of the /proc filesystem entries +contains a number in addition to the driver name. (E.g. "cciss0" +instead of just "cciss" which you might expect.) + +Note: ONLY sequential access devices and medium changers are presented +as SCSI devices to the SCSI mid layer by the cciss driver. Specifically, +physical SCSI disk drives are NOT presented to the SCSI mid layer. The +physical SCSI disk drives are controlled directly by the array controller +hardware and it is important to prevent the kernel from attempting to directly +access these devices too, as if the array controller were merely a SCSI +controller in the same way that we are allowing it to access SCSI tape drives. + +SCSI error handling for tape drives and medium changers +------------------------------------------------------- + +The linux SCSI mid layer provides an error handling protocol which +kicks into gear whenever a SCSI command fails to complete within a +certain amount of time (which can vary depending on the command). +The cciss driver participates in this protocol to some extent. The +normal protocol is a four step process. First the device is told +to abort the command. If that doesn't work, the device is reset. +If that doesn't work, the SCSI bus is reset. If that doesn't work +the host bus adapter is reset. Because the cciss driver is a block +driver as well as a SCSI driver and only the tape drives and medium +changers are presented to the SCSI mid layer, and unlike more +straightforward SCSI drivers, disk i/o continues through the block +side during the SCSI error recovery process, the cciss driver only +implements the first two of these actions, aborting the command, and +resetting the device. Additionally, most tape drives will not oblige +in aborting commands, and sometimes it appears they will not even +obey a reset command, though in most circumstances they will. In +the case that the command cannot be aborted and the device cannot be +reset, the device will be set offline. + +In the event the error handling code is triggered and a tape drive is +successfully reset or the tardy command is successfully aborted, the +tape drive may still not allow i/o to continue until some command +is issued which positions the tape to a known position. Typically you +must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example) +before i/o can proceed again to a tape drive which was reset. + diff --git a/Documentation/blockdev/cpqarray.txt b/Documentation/blockdev/cpqarray.txt new file mode 100644 index 00000000000..c7154e20ef5 --- /dev/null +++ b/Documentation/blockdev/cpqarray.txt @@ -0,0 +1,93 @@ +This driver is for Compaq's SMART2 Intelligent Disk Array Controllers. + +Supported Cards: +---------------- + +This driver is known to work with the following cards: + + * SMART (EISA) + * SMART-2/E (EISA) + * SMART-2/P + * SMART-2DH + * SMART-2SL + * SMART-221 + * SMART-3100ES + * SMART-3200 + * Integrated Smart Array Controller + * SA 4200 + * SA 4250ES + * SA 431 + * RAID LC2 Controller + +It should also work with some really old Disk array adapters, but I am +unable to test against these cards: + + * IDA + * IDA-2 + * IAES + + +EISA Controllers: +----------------- + +If you want to use an EISA controller you'll have to supply some +modprobe/lilo parameters.

Introduction + +Owing to the simplicity and near universality of the parallel port interface +to personal computers, many external devices such as portable hard-disk, +CD-ROM, LS-120 and tape drives use the parallel port to connect to their +host computer. While some devices (notably scanners) use ad-hoc methods +to pass commands and data through the parallel port interface, most +external devices are actually identical to an internal model, but with +a parallel-port adapter chip added in. Some of the original parallel port +adapters were little more than mechanisms for multiplexing a SCSI bus. +(The Iomega PPA-3 adapter used in the ZIP drives is an example of this +approach). Most current designs, however, take a different approach. +The adapter chip reproduces a small ISA or IDE bus in the external device +and the communication protocol provides operations for reading and writing +device registers, as well as data block transfer functions. Sometimes, +the device being addressed via the parallel cable is a standard SCSI +controller like an NCR 5380. The "ditto" family of external tape +drives use the ISA replicator to interface a floppy disk controller, +which is then connected to a floppy-tape mechanism. The vast majority +of external parallel port devices, however, are now based on standard +IDE type devices, which require no intermediate controller. If one +were to open up a parallel port CD-ROM drive, for instance, one would +find a standard ATAPI CD-ROM drive, a power supply, and a single adapter +that interconnected a standard PC parallel port cable and a standard +IDE cable. It is usually possible to exchange the CD-ROM device with +any other device using the IDE interface. + +The document describes the support in Linux for parallel port IDE +devices. It does not cover parallel port SCSI devices, "ditto" tape +drives or scanners. Many different devices are supported by the +parallel port IDE subsystem, including: + + MicroSolutions backpack CD-ROM + MicroSolutions backpack PD/CD + MicroSolutions backpack hard-drives + MicroSolutions backpack 8000t tape drive + SyQuest EZ-135, EZ-230 & SparQ drives + Avatar Shark + Imation Superdisk LS-120 + Maxell Superdisk LS-120 + FreeCom Power CD + Hewlett-Packard 5GB and 8GB tape drives + Hewlett-Packard 7100 and 7200 CD-RW drives + +as well as most of the clone and no-name products on the market. + +To support such a wide range of devices, PARIDE, the parallel port IDE +subsystem, is actually structured in three parts. There is a base +paride module which provides a registry and some common methods for +accessing the parallel ports. The second component is a set of +high-level drivers for each of the different types of supported devices: + + pd IDE disk + pcd ATAPI CD-ROM + pf ATAPI disk + pt ATAPI tape + pg ATAPI generic + +(Currently, the pg driver is only used with CD-R drives). + +The high-level drivers function according to the relevant standards. +The third component of PARIDE is a set of low-level protocol drivers +for each of the parallel port IDE adapter chips. Thanks to the interest +and encouragement of Linux users from many parts of the world, +support is available for almost all known adapter protocols: + + aten ATEN EH-100 (HK) + bpck Microsolutions backpack (US) + comm DataStor (old-type) "commuter" adapter (TW) + dstr DataStor EP-2000 (TW) + epat Shuttle EPAT (UK) + epia Shuttle EPIA (UK) + fit2 FIT TD-2000 (US) + fit3 FIT TD-3000 (US) + friq Freecom IQ cable (DE) + frpw Freecom Power (DE) + kbic KingByte KBIC-951A and KBIC-971A (TW) + ktti KT Technology PHd adapter (SG) + on20 OnSpec 90c20 (US) + on26 OnSpec 90c26 (US) + + +2. Using the PARIDE subsystem + +While configuring the Linux kernel, you may choose either to build +the PARIDE drivers into your kernel, or to build them as modules. + +In either case, you will need to select "Parallel port IDE device support" +as well as at least one of the high-level drivers and at least one +of the parallel port communication protocols. If you do not know +what kind of parallel port adapter is used in your drive, you could +begin by checking the file names and any text files on your DOS +installation floppy. Alternatively, you can look at the markings on +the adapter chip itself. That's usually sufficient to identify the +correct device. + +You can actually select all the protocol modules, and allow the PARIDE +subsystem to try them all for you. + +For the "brand-name" products listed above, here are the protocol +and high-level drivers that you would use: + + Manufacturer Model Driver Protocol + + MicroSolutions CD-ROM pcd bpck + MicroSolutions PD drive pf bpck + MicroSolutions hard-drive pd bpck + MicroSolutions 8000t tape pt bpck + SyQuest EZ, SparQ pd epat + Imation Superdisk pf epat + Maxell Superdisk pf friq + Avatar Shark pd epat + FreeCom CD-ROM pcd frpw + Hewlett-Packard 5GB Tape pt epat + Hewlett-Packard 7200e (CD) pcd epat + Hewlett-Packard 7200e (CD-R) pg epat + +2.1 Configuring built-in drivers + +We recommend that you get to know how the drivers work and how to +configure them as loadable modules, before attempting to compile a +kernel with the drivers built-in. + +If you built all of your PARIDE support directly into your kernel, +and you have just a single parallel port IDE device, your kernel should +locate it automatically for you. If you have more than one device, +you may need to give some command line options to your bootloader +(eg: LILO), how to do that is beyond the scope of this document. + +The high-level drivers accept a number of command line parameters, all +of which are documented in the source files in linux/drivers/block/paride. +By default, each driver will automatically try all parallel ports it +can find, and all protocol types that have been installed, until it finds +a parallel port IDE adapter. Once it finds one, the probe stops. So, +if you have more than one device, you will need to tell the drivers +how to identify them. This requires specifying the port address, the +protocol identification number and, for some devices, the drive's +chain ID. While your system is booting, a number of messages are +displayed on the console. Like all such messages, they can be +reviewed with the 'dmesg' command. Among those messages will be +some lines like: + + paride: bpck registered as protocol 0 + paride: epat registered as protocol 1 + +The numbers will always be the same until you build a new kernel with +different protocol selections. You should note these numbers as you +will need them to identify the devices. + +If you happen to be using a MicroSolutions backpack device, you will +also need to know the unit ID number for each drive. This is usually +the last two digits of the drive's serial number (but read MicroSolutions' +documentation about this). + +As an example, let's assume that you have a MicroSolutions PD/CD drive +with unit ID number 36 connected to the parallel port at 0x378, a SyQuest +EZ-135 connected to the chained port on the PD/CD drive and also an +Imation Superdisk connected to port 0x278. You could give the following +options on your boot command: + + pd.drive0=0x378,1 pf.drive0=0x278,1 pf.drive1=0x378,0,36 + +In the last option, pf.drive1 configures device /dev/pf1, the 0x378 +is the parallel port base address, the 0 is the protocol registration +number and 36 is the chain ID. + +Please note: while PARIDE will work both with and without the +PARPORT parallel port sharing system that is included by the +"Parallel port support" option, PARPORT must be included and enabled +if you want to use chains of devices on the same parallel port. + +2.2 Loading and configuring PARIDE as modules + +It is much faster and simpler to get to understand the PARIDE drivers +if you use them as loadable kernel modules. + +Note 1: using these drivers with the "kerneld" automatic module loading +system is not recommended for beginners, and is not documented here. + +Note 2: if you build PARPORT support as a loadable module, PARIDE must +also be built as loadable modules, and PARPORT must be loaded before the +PARIDE modules. + +To use PARIDE, you must begin by + + insmod paride + +this loads a base module which provides a registry for the protocols, +among other tasks. + +Then, load as many of the protocol modules as you think you might need. +As you load each module, it will register the protocols that it supports, +and print a log message to your kernel log file and your console. For +example: + + # insmod epat + paride: epat registered as protocol 0 + # insmod kbic + paride: k951 registered as protocol 1 + paride: k971 registered as protocol 2 + +Finally, you can load high-level drivers for each kind of device that +you have connected. By default, each driver will autoprobe for a single +device, but you can support up to four similar devices by giving their +individual co-ordinates when you load the driver. + +For example, if you had two no-name CD-ROM drives both using the +KingByte KBIC-951A adapter, one on port 0x378 and the other on 0x3bc +you could give the following command: + + # insmod pcd drive0=0x378,1 drive1=0x3bc,1 + +For most adapters, giving a port address and protocol number is sufficient, +but check the source files in linux/drivers/block/paride for more +information. (Hopefully someone will write some man pages one day !). + +As another example, here's what happens when PARPORT is installed, and +a SyQuest EZ-135 is attached to port 0x378: + + # insmod paride + paride: version 1.0 installed + # insmod epat + paride: epat registered as protocol 0 + # insmod pd + pd: pd version 1.0, major 45, cluster 64, nice 0 + pda: Sharing parport1 at 0x378 + pda: epat 1.0, Shuttle EPAT chip c3 at 0x378, mode 5 (EPP-32), delay 1 + pda: SyQuest EZ135A, 262144 blocks [128M], (512/16/32), removable media + pda: pda1 + +Note that the last line is the output from the generic partition table +scanner - in this case it reports that it has found a disk with one partition. + +2.3 Using a PARIDE device + +Once the drivers have been loaded, you can access PARIDE devices in the +same way as their traditional counterparts. You will probably need to +create the device "special files". Here is a simple script that you can +cut to a file and execute: + +#!/bin/bash +# +# mkd -- a script to create the device special files for the PARIDE subsystem +# +function mkdev { + mknod $1 $2 $3 $4 ; chmod 0660 $1 ; chown root:disk $1 +} +# +function pd { + D=$( printf \\$( printf "x%03x" $[ $1 + 97 ] ) ) + mkdev pd$D b 45 $[ $1 * 16 ] + for P in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 + do mkdev pd$D$P b 45 $[ $1 * 16 + $P ] + done +} +# +cd /dev +# +for u in 0 1 2 3 ; do pd $u ; done +for u in 0 1 2 3 ; do mkdev pcd$u b 46 $u ; done +for u in 0 1 2 3 ; do mkdev pf$u b 47 $u ; done +for u in 0 1 2 3 ; do mkdev pt$u c 96 $u ; done +for u in 0 1 2 3 ; do mkdev npt$u c 96 $[ $u + 128 ] ; done +for u in 0 1 2 3 ; do mkdev pg$u c 97 $u ; done +# +# end of mkd + +With the device files and drivers in place, you can access PARIDE devices +like any other Linux device. For example, to mount a CD-ROM in pcd0, use: + + mount /dev/pcd0 /cdrom + +If you have a fresh Avatar Shark cartridge, and the drive is pda, you +might do something like: + + fdisk /dev/pda -- make a new partition table with + partition 1 of type 83 + + mke2fs /dev/pda1 -- to build the file system + + mkdir /shark -- make a place to mount the disk + + mount /dev/pda1 /shark + +Devices like the Imation superdisk work in the same way, except that +they do not have a partition table. For example to make a 120MB +floppy that you could share with a DOS system: + + mkdosfs /dev/pf0 + mount /dev/pf0 /mnt + + +2.4 The pf driver + +The pf driver is intended for use with parallel port ATAPI disk +devices. The most common devices in this category are PD drives +and LS-120 drives. Traditionally, media for these devices are not +partitioned. Consequently, the pf driver does not support partitioned +media. This may be changed in a future version of the driver. + +2.5 Using the pt driver + +The pt driver for parallel port ATAPI tape drives is a minimal driver. +It does not yet support many of the standard tape ioctl operations. +For best performance, a block size of 32KB should be used. You will +probably want to set the parallel port delay to 0, if you can. + +2.6 Using the pg driver + +The pg driver can be used in conjunction with the cdrecord program +to create CD-ROMs. Please get cdrecord version 1.6.1 or later +from ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/ . To record CD-R media +your parallel port should ideally be set to EPP mode, and the "port delay" +should be set to 0. With those settings it is possible to record at 2x +speed without any buffer underruns. If you cannot get the driver to work +in EPP mode, try to use "bidirectional" or "PS/2" mode and 1x speeds only. + + +3. Troubleshooting + +3.1 Use EPP mode if you can + +The most common problems that people report with the PARIDE drivers +concern the parallel port CMOS settings. At this time, none of the +PARIDE protocol modules support ECP mode, or any ECP combination modes. +If you are able to do so, please set your parallel port into EPP mode +using your CMOS setup procedure. + +3.2 Check the port delay + +Some parallel ports cannot reliably transfer data at full speed. To +offset the errors, the PARIDE protocol modules introduce a "port +delay" between each access to the i/o ports. Each protocol sets +a default value for this delay. In most cases, the user can override +the default and set it to 0 - resulting in somewhat higher transfer +rates. In some rare cases (especially with older 486 systems) the +default delays are not long enough. if you experience corrupt data +transfers, or unexpected failures, you may wish to increase the +port delay. The delay can be programmed using the "driveN" parameters +to each of the high-level drivers. Please see the notes above, or +read the comments at the beginning of the driver source files in +linux/drivers/block/paride. + +3.3 Some drives need a printer reset + +There appear to be a number of "noname" external drives on the market +that do not always power up correctly. We have noticed this with some +drives based on OnSpec and older Freecom adapters. In these rare cases, +the adapter can often be reinitialised by issuing a "printer reset" on +the parallel port. As the reset operation is potentially disruptive in +multiple device environments, the PARIDE drivers will not do it +automatically. You can however, force a printer reset by doing: + + insmod lp reset=1 + rmmod lp + +If you have one of these marginal cases, you should probably build +your paride drivers as modules, and arrange to do the printer reset +before loading the PARIDE drivers. + +3.4 Use the verbose option and dmesg if you need help + +While a lot of testing has gone into these drivers to make them work +as smoothly as possible, problems will arise. If you do have problems, +please check all the obvious things first: does the drive work in +DOS with the manufacturer's drivers ? If that doesn't yield any useful +clues, then please make sure that only one drive is hooked to your system, +and that either (a) PARPORT is enabled or (b) no other device driver +is using your parallel port (check in /proc/ioports). Then, load the +appropriate drivers (you can load several protocol modules if you want) +as in: + + # insmod paride + # insmod epat + # insmod bpck + # insmod kbic + ... + # insmod pd verbose=1 + +(using the correct driver for the type of device you have, of course). +The verbose=1 parameter will cause the drivers to log a trace of their +activity as they attempt to locate your drive. + +Use 'dmesg' to capture a log of all the PARIDE messages (any messages +beginning with paride:, a protocol module's name or a driver's name) and +include that with your bug report. You can submit a bug report in one +of two ways. Either send it directly to the author of the PARIDE suite, +by e-mail to grant@torque.net, or join the linux-parport mailing list +and post your report there. + +3.5 For more information or help + +You can join the linux-parport mailing list by sending a mail message +to + linux-parport-request@torque.net + +with the single word + + subscribe + +in the body of the mail message (not in the subject line).

It can +also be used for a temporary filesystem for crypto work, since the contents +are erased on reboot. + +The RAM disk dynamically grows as more space is required. It does this by using +RAM from the buffer cache. The driver marks the buffers it is using as dirty +so that the VM subsystem does not try to reclaim them later. + +The RAM disk supports up to 16 RAM disks by default, and can be reconfigured +to support an unlimited number of RAM disks (at your own risk). Just change +the configuration symbol BLK_DEV_RAM_COUNT in the Block drivers config menu +and (re)build the kernel. + +To use RAM disk support with your system, run './MAKEDEV ram' from the /dev +directory. RAM disks are all major number 1, and start with minor number 0 +for /dev/ram0, etc. If used, modern kernels use /dev/ram0 for an initrd. + +The new RAM disk also has the ability to load compressed RAM disk images, +allowing one to squeeze more programs onto an average installation or +rescue floppy disk. + + +2) Kernel Command Line Parameters +--------------------------------- + + ramdisk_size=N + ============== + +This parameter tells the RAM disk driver to set up RAM disks of N k size. The +default is 4096 (4 MB) (8192 (8 MB) on S390). + + ramdisk_blocksize=N + =================== + +This parameter tells the RAM disk driver how many bytes to use per block. The +default is 1024 (BLOCK_SIZE). + + +3) Using "rdev -r" +------------------ + +The usage of the word (two bytes) that "rdev -r" sets in the kernel image is +as follows. The low 11 bits (0 -> 10) specify an offset (in 1 k blocks) of up +to 2 MB (2^11) of where to find the RAM disk (this used to be the size). Bit +14 indicates that a RAM disk is to be loaded, and bit 15 indicates whether a +prompt/wait sequence is to be given before trying to read the RAM disk. Since +the RAM disk dynamically grows as data is being written into it, a size field +is not required. Bits 11 to 13 are not currently used and may as well be zero. +These numbers are no magical secrets, as seen below: + +./arch/i386/kernel/setup.c:#define RAMDISK_IMAGE_START_MASK 0x07FF +./arch/i386/kernel/setup.c:#define RAMDISK_PROMPT_FLAG 0x8000 +./arch/i386/kernel/setup.c:#define RAMDISK_LOAD_FLAG 0x4000 + +Consider a typical two floppy disk setup, where you will have the +kernel on disk one, and have already put a RAM disk image onto disk #2. + +Hence you want to set bits 0 to 13 as 0, meaning that your RAM disk +starts at an offset of 0 kB from the beginning of the floppy. +The command line equivalent is: "ramdisk_start=0" + +You want bit 14 as one, indicating that a RAM disk is to be loaded. +The command line equivalent is: "load_ramdisk=1" + +You want bit 15 as one, indicating that you want a prompt/keypress +sequence so that you have a chance to switch floppy disks. +The command line equivalent is: "prompt_ramdisk=1" + +Putting that together gives 2^15 + 2^14 + 0 = 49152 for an rdev word. +So to create disk one of the set, you would do: + + /usr/src/linux# cat arch/i386/boot/zImage > /dev/fd0 + /usr/src/linux# rdev /dev/fd0 /dev/fd0 + /usr/src/linux# rdev -r /dev/fd0 49152 + +If you make a boot disk that has LILO, then for the above, you would use: + append = "ramdisk_start=0 load_ramdisk=1 prompt_ramdisk=1" +Since the default start = 0 and the default prompt = 1, you could use: + append = "load_ramdisk=1" + + +4) An Example of Creating a Compressed RAM Disk +---------------------------------------------- + +To create a RAM disk image, you will need a spare block device to +construct it on. This can be the RAM disk device itself, or an +unused disk partition (such as an unmounted swap partition). For this +example, we will use the RAM disk device, "/dev/ram0". + +Note: This technique should not be done on a machine with less than 8 MB +of RAM. If using a spare disk partition instead of /dev/ram0, then this +restriction does not apply. + +a) Decide on the RAM disk size that you want. Say 2 MB for this example. + Create it by writing to the RAM disk device. (This step is not currently + required, but may be in the future.) It is wise to zero out the + area (esp. for disks) so that maximal compression is achieved for + the unused blocks of the image that you are about to create. + + dd if=/dev/zero of=/dev/ram0 bs=1k count=2048 + +b) Make a filesystem on it. Say ext2fs for this example. + + mke2fs -vm0 /dev/ram0 2048 + +c) Mount it, copy the files you want to it (eg: /etc/* /dev/* ...) + and unmount it again. + +d) Compress the contents of the RAM disk. The level of compression + will be approximately 50% of the space used by the files. Unused + space on the RAM disk will compress to almost nothing. + + dd if=/dev/ram0 bs=1k count=2048 | gzip -v9 > /tmp/ram_image.gz + +e) Put the kernel onto the floppy + + dd if=zImage of=/dev/fd0 bs=1k + +f) Put the RAM disk image onto the floppy, after the kernel. Use an offset + that is slightly larger than the kernel, so that you can put another + (possibly larger) kernel onto the same floppy later without overlapping + the RAM disk image. An offset of 400 kB for kernels about 350 kB in + size would be reasonable. Make sure offset+size of ram_image.gz is + not larger than the total space on your floppy (usually 1440 kB). + + dd if=/tmp/ram_image.gz of=/dev/fd0 bs=1k seek=400 + +g) Use "rdev" to set the boot device, RAM disk offset, prompt flag, etc. + For prompt_ramdisk=1, load_ramdisk=1, ramdisk_start=400, one would + have 2^15 + 2^14 + 400 = 49552. + + rdev /dev/fd0 /dev/fd0 + rdev -r /dev/fd0 49552 + +That is it. You now have your boot/root compressed RAM disk floppy.

This is because at driver init time, -the SCSI core may not yet be initialized (because the driver is a block -driver) and attempting to register it with the SCSI core in such a case -would cause a hang.

Because the cciss driver is a block -driver as well as a SCSI driver and only the tape drives and medium -changers are presented to the SCSI mid layer, and unlike more -straightforward SCSI drivers, disk i/o continues through the block -side during the SCSI error recovery process, the cciss driver only -implements the first two of these actions, aborting the command, and -resetting the device.

INSTALLATION - -Previously, the driver sources were packaged with a set of patch files -to update the character drivers' makefile and configuration file, and other -kernel source files. A build script (ip2build) was included which applies -the patches if needed, and build any utilities needed. -What you receive may be a single patch file in conventional kernel -patch format build script. That form can also be applied by -running patch -p1 < ThePatchFile. Otherwise run ip2build. - -The driver can be installed as a module (recommended) or built into the -kernel. This is selected as for other drivers through the `make config` -command from the root of the Linux source tree. If the driver is built -into the kernel you will need to edit the file ip2.c to match the boards -you are installing. See that file for instructions. If the driver is -installed as a module the configuration can also be specified on the -modprobe command line as follows: - - modprobe ip2 irq=irq1,irq2,irq3,irq4 io=addr1,addr2,addr3,addr4 - -where irqnum is one of the valid Intelliport II interrupts (3,4,5,7,10,11, -12,15) and addr1-4 are the base addresses for up to four controllers. If -the irqs are not specified the driver uses the default in ip2.c (which -selects polled mode). If no base addresses are specified the defaults in -ip2.c are used. If you are autoloading the driver module with kerneld or -kmod the base addresses and interrupt number must also be set in ip2.c -and recompile or just insert and options line in /etc/modprobe.conf or both. -The options line is equivalent to the command line and takes precedence over -what is in ip2.c. - -/etc/modprobe.conf sample: - options ip2 io=1,0x328 irq=1,10 - alias char-major-71 ip2 - alias char-major-72 ip2 - alias char-major-73 ip2 - -The equivalent in ip2.c: - -static int io[IP2_MAX_BOARDS]= { 1, 0x328, 0, 0 }; -static int irq[IP2_MAX_BOARDS] = { 1, 10, -1, -1 }; - -The equivalent for the kernel command line (in lilo.conf): - - append="ip2=1,1,0x328,10" - - -Note: Both io and irq should be updated to reflect YOUR system. An "io" - address of 1 or 2 indicates a PCI or EISA card in the board table. - The PCI or EISA irq will be assigned automatically. - -Specifying an invalid or in-use irq will default the driver into -running in polled mode for that card. If all irq entries are 0 then -all cards will operate in polled mode. - -If you select the driver as part of the kernel run : - - make zlilo (or whatever you do to create a bootable kernel) - -If you selected a module run : - - make modules && make modules_install - -The utility ip2mkdev (see 5 and 7 below) creates all the device nodes -required by the driver. For a device to be created it must be configured -in the driver and the board must be installed. Only devices corresponding -to real IntelliPort II ports are created. With multiple boards and expansion -boxes this will leave gaps in the sequence of device names. ip2mkdev uses -Linux tty naming conventions: ttyF0 - ttyF255 for normal devices, and -cuf0 - cuf255 for callout devices. - - -4. USING THE DRIVERS - -As noted above, the driver implements the ports in accordance with Linux -conventions, and the devices should be interchangeable with the standard -serial devices. (This is a key point for problem reporting: please make -sure that what you are trying do works on the ttySx/cuax ports first; then -tell us what went wrong with the ip2 ports!) - -Higher speeds can be obtained using the setserial utility which remaps -38,400 bps (extb) to 57,600 bps, 115,200 bps, or a custom speed. -Intelliport II installations using the PowerPort expansion module can -use the custom speed setting to select the highest speeds: 153,600 bps, -230,400 bps, 307,200 bps, 460,800bps and 921,600 bps. The base for -custom baud rate configuration is fixed at 921,600 for cards/expansion -modules with ST654's and 115200 for those with Cirrus CD1400's. This -corresponds to the maximum bit rates those chips are capable. -For example if the baud base is 921600 and the baud divisor is 18 then -the custom rate is 921600/18 = 51200 bps. See the setserial man page for -complete details. Of course if stty accepts the higher rates now you can -use that as well as the standard ioctls(). - - -5. ip2mkdev and assorted utilities... - -Several utilities, including the source for a binary ip2mkdev utility are -available under .../drivers/char/ip2. These can be build by changing to -that directory and typing "make" after the kernel has be built. If you do -not wish to compile the binary utilities, the shell script below can be -cut out and run as "ip2mkdev" to create the necessary device files. To -use the ip2mkdev script, you must have procfs enabled and the proc file -system mounted on /proc. - - -6. NOTES - -This is a release version of the driver, but it is impossible to test it -in all configurations of Linux. If there is any anomalous behaviour that -does not match the standard serial port's behaviour please let us know. - - -7. ip2mkdev shell script - -Previously, this script was simply attached here.

This may speed up certain operations. - - floppy=0,daring - Tells the floppy driver that your floppy controller should be used - with caution. - - floppy=one_fdc - Tells the floppy driver that you have only one floppy controller. - (default) - - floppy=two_fdc - floppy=

Thinkpads use an - inverted convention for the disk change line. - - floppy=0,thinkpad - Tells the floppy driver that you don't have a Thinkpad. - - floppy=omnibook - floppy=nodma - Tells the floppy driver not to use Dma for data transfers. - This is needed on HP Omnibooks, which don't have a workable - DMA channel for the floppy driver. This option is also useful - if you frequently get "Unable to allocate DMA memory" messages. - Indeed, dma memory needs to be continuous in physical memory, - and is thus harder to find, whereas non-dma buffers may be - allocated in virtual memory. However, I advise against this if - you have an FDC without a FIFO (8272A or 82072). 82072A and - later are OK. You also need at least a 486 to use nodma. - If you use nodma mode, I suggest you also set the FIFO - threshold to 10 or lower, in order to limit the number of data - transfer interrupts. - - If you have a FIFO-able FDC, the floppy driver automatically - falls back on non DMA mode if no DMA-able memory can be found. - If you want to avoid this, explicitly ask for 'yesdma'. - - floppy=yesdma - Tells the floppy driver that a workable DMA channel is available. - (default) - - floppy=nofifo - Disables the FIFO entirely. This is needed if you get "Bus - master arbitration error" messages from your Ethernet card (or - from other devices) while accessing the floppy. - - floppy=usefifo - Enables the FIFO. (default) - - floppy=,fifo_depth - Sets the FIFO threshold. This is mostly relevant in DMA - mode. If this is higher, the floppy driver tolerates more - interrupt latency, but it triggers more interrupts (i.e. it - imposes more load on the rest of the system). If this is - lower, the interrupt latency should be lower too (faster - processor). The benefit of a lower threshold is less - interrupts. - - To tune the fifo threshold, switch on over/underrun messages - using 'floppycontrol --messages'. Then access a floppy - disk. If you get a huge amount of "Over/Underrun - retrying" - messages, then the fifo threshold is too low. Try with a - higher value, until you only get an occasional Over/Underrun. - It is a good idea to compile the floppy driver as a module - when doing this tuning. Indeed, it allows to try different - fifo values without rebooting the machine for each test. Note - that you need to do 'floppycontrol --messages' every time you - re-insert the module. - - Usually, tuning the fifo threshold should not be needed, as - the default (0xa) is reasonable. - - floppy=,,cmos - Sets the CMOS type of to .

This is because 5 was - initially chosen to represent floppy *tapes*, and 6 for ED drives. - AMI ignored this, and used 5 for ED drives.

Needed on some - boxes where the disk change line is broken or unsupported. - This should be regarded as a stopgap measure, indeed it makes - floppy operation less efficient due to unneeded cache - flushings, and slightly more unreliable.

The format is: - -irq=[0x100],[0x140],[0x180],[0x200],[0x240],[0x280],[0x300],[0x380] - -The address in brackets is the base address of the card. The IRQ of -nonexistent cards can be set to 0. If an IRQ of a card that does exist is set -to 0, the driver will attempt to guess at the correct IRQ. For example, to set -the IRQ of the card at address 0x300 to 12, the insmod command would be: - -insmod esp irq=0,0,0,0,0,0,12,0 - -The custom divisor can be set by using the divisor= option. The format is the -same as for the irq= option. Each divisor value is a series of hex digits, -with each digit representing the divisor to use for a corresponding port. The -divisor value is constructed RIGHT TO LEFT. Specifying a nonzero divisor value -will automatically set the spd_cust flag.

This -value indicates how long after receiving the last character that the ESP card -should wait before signalling an interrupt. Valid values are 0 though 255, -with 128 being the default. A value too high will increase latency, and a -value too low will cause unnecessary interrupts. For example, to set the -receive timeout to 255, the insmod command would be: - -insmod esp rx_timeout=255 - -The pio_threshold= option sets the threshold (in number of characters) for -using PIO mode instead of DMA mode.

Up to - 4 Moxa Smartio/Industio PCI Family multiport boards can be installed - together on one system and they can share the same IRQ. - - - 3.2 Driver files - - The driver file may be obtained from ftp, CD-ROM or floppy disk. The - first step, anyway, is to copy driver file "mxser.tgz" into specified - directory. e.g. /moxa. The execute commands as below. - - # cd / - # mkdir moxa - # cd /moxa - # tar xvf /dev/fd0 - - or - - # cd / - # mkdir moxa - # cd /moxa - # cp /mnt/cdrom//mxser.tgz . - # tar xvfz mxser.tgz - - - 3.3 Device naming convention - - You may find all the driver and utilities files in /moxa/mxser. - Following installation procedure depends on the model you'd like to - run the driver. If you prefer module driver, please refer to 3.4. - If static driver is required, please refer to 3.5. - - Dialin and callout port - ----------------------- - This driver remains traditional serial device properties. There are - two special file name for each serial port. One is dial-in port - which is named "ttyMxx". For callout port, the naming convention - is "cumxx". - - Device naming when more than 2 boards installed - ----------------------------------------------- - Naming convention for each Smartio/Industio multiport board is - pre-defined as below. - - Board Num. Dial-in Port Callout port - 1st board ttyM0 - ttyM7 cum0 - cum7 - 2nd board ttyM8 - ttyM15 cum8 - cum15 - 3rd board ttyM16 - ttyM23 cum16 - cum23 - 4th board ttyM24 - ttym31 cum24 - cum31 - - - !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! - Under Kernel 2.6 the cum Device is Obsolete. So use ttyM* - device instead. - !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! - - Board sequence - -------------- - This driver will activate ISA boards according to the parameter set - in the driver. After all specified ISA board activated, PCI board - will be installed in the system automatically driven. - Therefore the board number is sorted by the CAP address of ISA boards. - For PCI boards, their sequence will be after ISA boards and C168H/PCI - has higher priority than C104H/PCI boards. - - 3.4 Module driver configuration - Module driver is easiest way to install. If you prefer static driver - installation, please skip this paragraph. - - - ------------- Prepare to use the MOXA driver-------------------- - 3.4.1 Create tty device with correct major number - Before using MOXA driver, your system must have the tty devices - which are created with driver's major number. We offer one shell - script "msmknod" to simplify the procedure. - This step is only needed to be executed once. But you still - need to do this procedure when: - a. You change the driver's major number. Please refer the "3.7" - section. - b. Your total installed MOXA boards number is changed. Maybe you - add/delete one MOXA board. - c. You want to change the tty name. This needs to modify the - shell script "msmknod" - - The procedure is: - # cd /moxa/mxser/driver - # ./msmknod - - This shell script will require the major number for dial-in - device and callout device to create tty device. You also need - to specify the total installed MOXA board number. Default major - numbers for dial-in device and callout device are 30, 35. If - you need to change to other number, please refer section "3.7" - for more detailed procedure. - Msmknod will delete any special files occupying the same device - naming. - - 3.4.2 Build the MOXA driver and utilities - Before using the MOXA driver and utilities, you need compile the - all the source code. This step is only need to be executed once. - But you still re-compile the source code if you modify the source - code. For example, if you change the driver's major number (see - "3.7" section), then you need to do this step again. - - Find "Makefile" in /moxa/mxser, then run - - # make clean; make install - - !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!! - For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1: - # make clean; make installsp1 - - For Red Hat Enterprise Linux AS4/ES4/WS4: - # make clean; make installsp2 - !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!! - - The driver files "mxser.o" and utilities will be properly compiled - and copied to system directories respectively. - - ------------- Load MOXA driver-------------------- - 3.4.3 Load the MOXA driver - - # modprobe mxser - - will activate the module driver. You may run "lsmod" to check - if "mxser" is activated. If the MOXA board is ISA board, the - is needed. Please refer to section "3.4.5" for more - information. - - - ------------- Load MOXA driver on boot -------------------- - 3.4.4 For the above description, you may manually execute - "modprobe mxser" to activate this driver and run - "rmmod mxser" to remove it. - However, it's better to have a boot time configuration to - eliminate manual operation. Boot time configuration can be - achieved by rc file. We offer one "rc.mxser" file to simplify - the procedure under "moxa/mxser/driver". - - But if you use ISA board, please modify the "modprobe ..." command - to add the argument (see "3.4.5" section). After modifying the - rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser" - manually to make sure the modification is ok. If any error - encountered, please try to modify again. If the modification is - completed, follow the below step. - - Run following command for setting rc files. - - # cd /moxa/mxser/driver - # cp ./rc.mxser /etc/rc.d - # cd /etc/rc.d - - Check "rc.serial" is existed or not. If "rc.serial" doesn't exist, - create it by vi, run "chmod 755 rc.serial" to change the permission. - Add "/etc/rc.d/rc.mxser" in last line, - - Reboot and check if moxa.o activated by "lsmod" command. - - 3.4.5. If you'd like to drive Smartio/Industio ISA boards in the system, - you'll have to add parameter to specify CAP address of given - board while activating "mxser.o". The format for parameters are - as follows. - - modprobe mxser ioaddr=0x???,0x???,0x???,0x??? - | | | | - | | | +- 4th ISA board - | | +------ 3rd ISA board - | +------------ 2nd ISA board - +------------------- 1st ISA board - - 3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x - - Note: To use static driver, you must install the linux kernel - source package. - - 3.5.1 Backup the built-in driver in the kernel. - # cd /usr/src/linux/drivers/char - # mv mxser.c mxser.c.old - - For Red Hat 7.x user, you need to create link: - # cd /usr/src - # ln -s linux-2.4 linux - - 3.5.2 Create link - # cd /usr/src/linux/drivers/char - # ln -s /moxa/mxser/driver/mxser.c mxser.c - - 3.5.3 Add CAP address list for ISA boards. For PCI boards user, - please skip this step. - - In module mode, the CAP address for ISA board is given by - parameter. In static driver configuration, you'll have to - assign it within driver's source code. If you will not - install any ISA boards, you may skip to next portion. - The instructions to modify driver source code are as - below. - a. # cd /moxa/mxser/driver - # vi mxser.c - b. Find the array mxserBoardCAP[] as below. - - static int mxserBoardCAP[] - = {0x00, 0x00, 0x00, 0x00}; - - c. Change the address within this array using vi. For - example, to driver 2 ISA boards with CAP address - 0x280 and 0x180 as 1st and 2nd board. Just to change - the source code as follows. - - static int mxserBoardCAP[] - = {0x280, 0x180, 0x00, 0x00}; - - 3.5.4 Setup kernel configuration - - Configure the kernel: - - # cd /usr/src/linux - # make menuconfig - - You will go into a menu-driven system. Please select [Character - devices][Non-standard serial port support], enable the [Moxa - SmartIO support] driver with "[*]" for built-in (not "[M]"), then - select [Exit] to exit this program. - - 3.5.5 Rebuild kernel - The following are for Linux kernel rebuilding, for your - reference only. - For appropriate details, please refer to the Linux document. - - a. cd /usr/src/linux - b. make clean /* take a few minutes */ - c. make dep /* take a few minutes */ - d. make bzImage /* take probably 10-20 minutes */ - e. make install /* copy boot image to correct position */ - f. Please make sure the boot kernel (vmlinuz) is in the - correct position. - g. If you use 'lilo' utility, you should check /etc/lilo.conf - 'image' item specified the path which is the 'vmlinuz' path, - or you will load wrong (or old) boot kernel image (vmlinuz). - After checking /etc/lilo.conf, please run "lilo". - - Note that if the result of "make bzImage" is ERROR, then you have to - go back to Linux configuration Setup. Type "make menuconfig" in - directory /usr/src/linux. - - - 3.5.6 Make tty device and special file - # cd /moxa/mxser/driver - # ./msmknod - - 3.5.7 Make utility - # cd /moxa/mxser/utility - # make clean; make install - - 3.5.8 Reboot - - - - 3.6 Custom configuration - Although this driver already provides you default configuration, you - still can change the device name and major number. The instruction to - change these parameters are shown as below. - - Change Device name - ------------------ - If you'd like to use other device names instead of default naming - convention, all you have to do is to modify the internal code - within the shell script "msmknod". First, you have to open "msmknod" - by vi. Locate each line contains "ttyM" and "cum" and change them - to the device name you desired. "msmknod" creates the device names - you need next time executed. - - Change Major number - ------------------- - If major number 30 and 35 had been occupied, you may have to select - 2 free major numbers for this driver. There are 3 steps to change - major numbers. - - 3.6.1 Find free major numbers - In /proc/devices, you may find all the major numbers occupied - in the system. Please select 2 major numbers that are available. - e.g. 40, 45. - 3.6.2 Create special files - Run /moxa/mxser/driver/msmknod to create special files with - specified major numbers. - 3.6.3 Modify driver with new major number - Run vi to open /moxa/mxser/driver/mxser.c. Locate the line - contains "MXSERMAJOR". Change the content as below. - #define MXSERMAJOR 40 - #define MXSERCUMAJOR 45 - 3.6.4 Run "make clean; make install" in /moxa/mxser/driver. - - 3.7 Verify driver installation - You may refer to /var/log/messages to check the latest status - log reported by this driver whenever it's activated. - ------------------------------------------------------------------------------ -4. Utilities - There are 3 utilities contained in this driver. They are msdiag, msmon and - msterm. These 3 utilities are released in form of source code. They should - be compiled into executable file and copied into /usr/bin. - - Before using these utilities, please load driver (refer 3.4 & 3.5) and - make sure you had run the "msmknod" utility. - - msdiag - Diagnostic - -------------------- - This utility provides the function to display what Moxa Smartio/Industio - board found by driver in the system. - - msmon - Port Monitoring - ----------------------- - This utility gives the user a quick view about all the MOXA ports' - activities. One can easily learn each port's total received/transmitted - (Rx/Tx) character count since the time when the monitoring is started. - Rx/Tx throughputs per second are also reported in interval basis (e.g. - the last 5 seconds) and in average basis (since the time the monitoring - is started). You can reset all ports' count by key. <+> <-> - (plus/minus) keys to change the displaying time interval. Press - on the port, that cursor stay, to view the port's communication - parameters, signal status, and input/output queue. - - msterm - Terminal Emulation - --------------------------- - This utility provides data sending and receiving ability of all tty ports, - especially for MOXA ports. It is quite useful for testing simple - application, for example, sending AT command to a modem connected to the - port or used as a terminal for login purpose. Note that this is only a - dumb terminal emulation without handling full screen operation. - ------------------------------------------------------------------------------ -5. Setserial - - Supported Setserial parameters are listed as below. - - uart set UART type(16450-->disable FIFO, 16550A-->enable FIFO) - close_delay set the amount of time(in 1/100 of a second) that DTR - should be kept low while being closed. - closing_wait set the amount of time(in 1/100 of a second) that the - serial port should wait for data to be drained while - being closed, before the receiver is disable. - spd_hi Use 57.6kb when the application requests 38.4kb. - spd_vhi Use 115.2kb when the application requests 38.4kb. - spd_shi Use 230.4kb when the application requests 38.4kb. - spd_warp Use 460.8kb when the application requests 38.4kb. - spd_normal Use 38.4kb when the application requests 38.4kb. - spd_cust Use the custom divisor to set the speed when the - application requests 38.4kb. - divisor This option set the custom divison. - baud_base This option set the base baud rate. - ------------------------------------------------------------------------------ -6. Troubleshooting - - The boot time error messages and solutions are stated as clearly as - possible. If all the possible solutions fail, please contact our technical - support team to get more help. - - - Error msg: More than 4 Moxa Smartio/Industio family boards found. Fifth board - and after are ignored. - Solution: - To avoid this problem, please unplug fifth and after board, because Moxa - driver supports up to 4 boards. - - Error msg: Request_irq fail, IRQ(?) may be conflict with another device. - Solution: - Other PCI or ISA devices occupy the assigned IRQ. If you are not sure - which device causes the situation, please check /proc/interrupts to find - free IRQ and simply change another free IRQ for Moxa board. - - Error msg: Board #: C1xx Series(CAP=xxx) interrupt number invalid. - Solution: - Each port within the same multiport board shares the same IRQ. Please set - one IRQ (IRQ doesn't equal to zero) for one Moxa board. - - Error msg: No interrupt vector be set for Moxa ISA board(CAP=xxx). - Solution: - Moxa ISA board needs an interrupt vector.Please refer to user's manual - "Hardware Installation" chapter to set interrupt vector. - - Error msg: Couldn't install MOXA Smartio/Industio family driver! - Solution: - Load Moxa driver fail, the major number may conflict with other devices. - Please refer to previous section 3.7 to change a free major number for - Moxa driver. - - Error msg: Couldn't install MOXA Smartio/Industio family callout driver! - Solution: - Load Moxa callout driver fail, the callout device major number may - conflict with other devices.

Introduction - -Owing to the simplicity and near universality of the parallel port interface -to personal computers, many external devices such as portable hard-disk, -CD-ROM, LS-120 and tape drives use the parallel port to connect to their -host computer. While some devices (notably scanners) use ad-hoc methods -to pass commands and data through the parallel port interface, most -external devices are actually identical to an internal model, but with -a parallel-port adapter chip added in. Some of the original parallel port -adapters were little more than mechanisms for multiplexing a SCSI bus. -(The Iomega PPA-3 adapter used in the ZIP drives is an example of this -approach). Most current designs, however, take a different approach. -The adapter chip reproduces a small ISA or IDE bus in the external device -and the communication protocol provides operations for reading and writing -device registers, as well as data block transfer functions. Sometimes, -the device being addressed via the parallel cable is a standard SCSI -controller like an NCR 5380. The "ditto" family of external tape -drives use the ISA replicator to interface a floppy disk controller, -which is then connected to a floppy-tape mechanism. The vast majority -of external parallel port devices, however, are now based on standard -IDE type devices, which require no intermediate controller. If one -were to open up a parallel port CD-ROM drive, for instance, one would -find a standard ATAPI CD-ROM drive, a power supply, and a single adapter -that interconnected a standard PC parallel port cable and a standard -IDE cable. It is usually possible to exchange the CD-ROM device with -any other device using the IDE interface. - -The document describes the support in Linux for parallel port IDE -devices. It does not cover parallel port SCSI devices, "ditto" tape -drives or scanners. Many different devices are supported by the -parallel port IDE subsystem, including: - - MicroSolutions backpack CD-ROM - MicroSolutions backpack PD/CD - MicroSolutions backpack hard-drives - MicroSolutions backpack 8000t tape drive - SyQuest EZ-135, EZ-230 & SparQ drives - Avatar Shark - Imation Superdisk LS-120 - Maxell Superdisk LS-120 - FreeCom Power CD - Hewlett-Packard 5GB and 8GB tape drives - Hewlett-Packard 7100 and 7200 CD-RW drives - -as well as most of the clone and no-name products on the market. - -To support such a wide range of devices, PARIDE, the parallel port IDE -subsystem, is actually structured in three parts. There is a base -paride module which provides a registry and some common methods for -accessing the parallel ports. The second component is a set of -high-level drivers for each of the different types of supported devices: - - pd IDE disk - pcd ATAPI CD-ROM - pf ATAPI disk - pt ATAPI tape - pg ATAPI generic - -(Currently, the pg driver is only used with CD-R drives). - -The high-level drivers function according to the relevant standards. -The third component of PARIDE is a set of low-level protocol drivers -for each of the parallel port IDE adapter chips. Thanks to the interest -and encouragement of Linux users from many parts of the world, -support is available for almost all known adapter protocols: - - aten ATEN EH-100 (HK) - bpck Microsolutions backpack (US) - comm DataStor (old-type) "commuter" adapter (TW) - dstr DataStor EP-2000 (TW) - epat Shuttle EPAT (UK) - epia Shuttle EPIA (UK) - fit2 FIT TD-2000 (US) - fit3 FIT TD-3000 (US) - friq Freecom IQ cable (DE) - frpw Freecom Power (DE) - kbic KingByte KBIC-951A and KBIC-971A (TW) - ktti KT Technology PHd adapter (SG) - on20 OnSpec 90c20 (US) - on26 OnSpec 90c26 (US) - - -2. Using the PARIDE subsystem - -While configuring the Linux kernel, you may choose either to build -the PARIDE drivers into your kernel, or to build them as modules. - -In either case, you will need to select "Parallel port IDE device support" -as well as at least one of the high-level drivers and at least one -of the parallel port communication protocols. If you do not know -what kind of parallel port adapter is used in your drive, you could -begin by checking the file names and any text files on your DOS -installation floppy. Alternatively, you can look at the markings on -the adapter chip itself. That's usually sufficient to identify the -correct device. - -You can actually select all the protocol modules, and allow the PARIDE -subsystem to try them all for you. - -For the "brand-name" products listed above, here are the protocol -and high-level drivers that you would use: - - Manufacturer Model Driver Protocol - - MicroSolutions CD-ROM pcd bpck - MicroSolutions PD drive pf bpck - MicroSolutions hard-drive pd bpck - MicroSolutions 8000t tape pt bpck - SyQuest EZ, SparQ pd epat - Imation Superdisk pf epat - Maxell Superdisk pf friq - Avatar Shark pd epat - FreeCom CD-ROM pcd frpw - Hewlett-Packard 5GB Tape pt epat - Hewlett-Packard 7200e (CD) pcd epat - Hewlett-Packard 7200e (CD-R) pg epat - -2.1 Configuring built-in drivers - -We recommend that you get to know how the drivers work and how to -configure them as loadable modules, before attempting to compile a -kernel with the drivers built-in. - -If you built all of your PARIDE support directly into your kernel, -and you have just a single parallel port IDE device, your kernel should -locate it automatically for you. If you have more than one device, -you may need to give some command line options to your bootloader -(eg: LILO), how to do that is beyond the scope of this document. - -The high-level drivers accept a number of command line parameters, all -of which are documented in the source files in linux/drivers/block/paride. -By default, each driver will automatically try all parallel ports it -can find, and all protocol types that have been installed, until it finds -a parallel port IDE adapter. Once it finds one, the probe stops. So, -if you have more than one device, you will need to tell the drivers -how to identify them. This requires specifying the port address, the -protocol identification number and, for some devices, the drive's -chain ID. While your system is booting, a number of messages are -displayed on the console. Like all such messages, they can be -reviewed with the 'dmesg' command. Among those messages will be -some lines like: - - paride: bpck registered as protocol 0 - paride: epat registered as protocol 1 - -The numbers will always be the same until you build a new kernel with -different protocol selections. You should note these numbers as you -will need them to identify the devices. - -If you happen to be using a MicroSolutions backpack device, you will -also need to know the unit ID number for each drive. This is usually -the last two digits of the drive's serial number (but read MicroSolutions' -documentation about this). - -As an example, let's assume that you have a MicroSolutions PD/CD drive -with unit ID number 36 connected to the parallel port at 0x378, a SyQuest -EZ-135 connected to the chained port on the PD/CD drive and also an -Imation Superdisk connected to port 0x278. You could give the following -options on your boot command: - - pd.drive0=0x378,1 pf.drive0=0x278,1 pf.drive1=0x378,0,36 - -In the last option, pf.drive1 configures device /dev/pf1, the 0x378 -is the parallel port base address, the 0 is the protocol registration -number and 36 is the chain ID. - -Please note: while PARIDE will work both with and without the -PARPORT parallel port sharing system that is included by the -"Parallel port support" option, PARPORT must be included and enabled -if you want to use chains of devices on the same parallel port. - -2.2 Loading and configuring PARIDE as modules - -It is much faster and simpler to get to understand the PARIDE drivers -if you use them as loadable kernel modules. - -Note 1: using these drivers with the "kerneld" automatic module loading -system is not recommended for beginners, and is not documented here. - -Note 2: if you build PARPORT support as a loadable module, PARIDE must -also be built as loadable modules, and PARPORT must be loaded before the -PARIDE modules. - -To use PARIDE, you must begin by - - insmod paride - -this loads a base module which provides a registry for the protocols, -among other tasks. - -Then, load as many of the protocol modules as you think you might need. -As you load each module, it will register the protocols that it supports, -and print a log message to your kernel log file and your console. For -example: - - # insmod epat - paride: epat registered as protocol 0 - # insmod kbic - paride: k951 registered as protocol 1 - paride: k971 registered as protocol 2 - -Finally, you can load high-level drivers for each kind of device that -you have connected. By default, each driver will autoprobe for a single -device, but you can support up to four similar devices by giving their -individual co-ordinates when you load the driver. - -For example, if you had two no-name CD-ROM drives both using the -KingByte KBIC-951A adapter, one on port 0x378 and the other on 0x3bc -you could give the following command: - - # insmod pcd drive0=0x378,1 drive1=0x3bc,1 - -For most adapters, giving a port address and protocol number is sufficient, -but check the source files in linux/drivers/block/paride for more -information. (Hopefully someone will write some man pages one day !). - -As another example, here's what happens when PARPORT is installed, and -a SyQuest EZ-135 is attached to port 0x378: - - # insmod paride - paride: version 1.0 installed - # insmod epat - paride: epat registered as protocol 0 - # insmod pd - pd: pd version 1.0, major 45, cluster 64, nice 0 - pda: Sharing parport1 at 0x378 - pda: epat 1.0, Shuttle EPAT chip c3 at 0x378, mode 5 (EPP-32), delay 1 - pda: SyQuest EZ135A, 262144 blocks [128M], (512/16/32), removable media - pda: pda1 - -Note that the last line is the output from the generic partition table -scanner - in this case it reports that it has found a disk with one partition. - -2.3 Using a PARIDE device - -Once the drivers have been loaded, you can access PARIDE devices in the -same way as their traditional counterparts. You will probably need to -create the device "special files". Here is a simple script that you can -cut to a file and execute: - -#!/bin/bash -# -# mkd -- a script to create the device special files for the PARIDE subsystem -# -function mkdev { - mknod $1 $2 $3 $4 ; chmod 0660 $1 ; chown root:disk $1 -} -# -function pd { - D=$( printf \\$( printf "x%03x" $[ $1 + 97 ] ) ) - mkdev pd$D b 45 $[ $1 * 16 ] - for P in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 - do mkdev pd$D$P b 45 $[ $1 * 16 + $P ] - done -} -# -cd /dev -# -for u in 0 1 2 3 ; do pd $u ; done -for u in 0 1 2 3 ; do mkdev pcd$u b 46 $u ; done -for u in 0 1 2 3 ; do mkdev pf$u b 47 $u ; done -for u in 0 1 2 3 ; do mkdev pt$u c 96 $u ; done -for u in 0 1 2 3 ; do mkdev npt$u c 96 $[ $u + 128 ] ; done -for u in 0 1 2 3 ; do mkdev pg$u c 97 $u ; done -# -# end of mkd - -With the device files and drivers in place, you can access PARIDE devices -like any other Linux device. For example, to mount a CD-ROM in pcd0, use: - - mount /dev/pcd0 /cdrom - -If you have a fresh Avatar Shark cartridge, and the drive is pda, you -might do something like: - - fdisk /dev/pda -- make a new partition table with - partition 1 of type 83 - - mke2fs /dev/pda1 -- to build the file system - - mkdir /shark -- make a place to mount the disk - - mount /dev/pda1 /shark - -Devices like the Imation superdisk work in the same way, except that -they do not have a partition table. For example to make a 120MB -floppy that you could share with a DOS system: - - mkdosfs /dev/pf0 - mount /dev/pf0 /mnt - - -2.4 The pf driver - -The pf driver is intended for use with parallel port ATAPI disk -devices. The most common devices in this category are PD drives -and LS-120 drives. Traditionally, media for these devices are not -partitioned. Consequently, the pf driver does not support partitioned -media. This may be changed in a future version of the driver. - -2.5 Using the pt driver - -The pt driver for parallel port ATAPI tape drives is a minimal driver. -It does not yet support many of the standard tape ioctl operations. -For best performance, a block size of 32KB should be used. You will -probably want to set the parallel port delay to 0, if you can. - -2.6 Using the pg driver - -The pg driver can be used in conjunction with the cdrecord program -to create CD-ROMs. Please get cdrecord version 1.6.1 or later -from ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/ . To record CD-R media -your parallel port should ideally be set to EPP mode, and the "port delay" -should be set to 0. With those settings it is possible to record at 2x -speed without any buffer underruns. If you cannot get the driver to work -in EPP mode, try to use "bidirectional" or "PS/2" mode and 1x speeds only. - - -3. Troubleshooting - -3.1 Use EPP mode if you can - -The most common problems that people report with the PARIDE drivers -concern the parallel port CMOS settings. At this time, none of the -PARIDE protocol modules support ECP mode, or any ECP combination modes. -If you are able to do so, please set your parallel port into EPP mode -using your CMOS setup procedure. - -3.2 Check the port delay - -Some parallel ports cannot reliably transfer data at full speed. To -offset the errors, the PARIDE protocol modules introduce a "port -delay" between each access to the i/o ports. Each protocol sets -a default value for this delay. In most cases, the user can override -the default and set it to 0 - resulting in somewhat higher transfer -rates. In some rare cases (especially with older 486 systems) the -default delays are not long enough. if you experience corrupt data -transfers, or unexpected failures, you may wish to increase the -port delay. The delay can be programmed using the "driveN" parameters -to each of the high-level drivers. Please see the notes above, or -read the comments at the beginning of the driver source files in -linux/drivers/block/paride. - -3.3 Some drives need a printer reset - -There appear to be a number of "noname" external drives on the market -that do not always power up correctly. We have noticed this with some -drives based on OnSpec and older Freecom adapters. In these rare cases, -the adapter can often be reinitialised by issuing a "printer reset" on -the parallel port. As the reset operation is potentially disruptive in -multiple device environments, the PARIDE drivers will not do it -automatically. You can however, force a printer reset by doing: - - insmod lp reset=1 - rmmod lp - -If you have one of these marginal cases, you should probably build -your paride drivers as modules, and arrange to do the printer reset -before loading the PARIDE drivers. - -3.4 Use the verbose option and dmesg if you need help - -While a lot of testing has gone into these drivers to make them work -as smoothly as possible, problems will arise. If you do have problems, -please check all the obvious things first: does the drive work in -DOS with the manufacturer's drivers ? If that doesn't yield any useful -clues, then please make sure that only one drive is hooked to your system, -and that either (a) PARPORT is enabled or (b) no other device driver -is using your parallel port (check in /proc/ioports). Then, load the -appropriate drivers (you can load several protocol modules if you want) -as in: - - # insmod paride - # insmod epat - # insmod bpck - # insmod kbic - ... - # insmod pd verbose=1 - -(using the correct driver for the type of device you have, of course). -The verbose=1 parameter will cause the drivers to log a trace of their -activity as they attempt to locate your drive. - -Use 'dmesg' to capture a log of all the PARIDE messages (any messages -beginning with paride:, a protocol module's name or a driver's name) and -include that with your bug report. You can submit a bug report in one -of two ways. Either send it directly to the author of the PARIDE suite, -by e-mail to grant@torque.net, or join the linux-parport mailing list -and post your report there. - -3.5 For more information or help - -You can join the linux-parport mailing list by sending a mail message -to - linux-parport-request@torque.net - -with the single word - - subscribe - -in the body of the mail message (not in the subject line).

Just change -the configuration symbol BLK_DEV_RAM_COUNT in the Block drivers config menu -and (re)build the kernel. - -To use RAM disk support with your system, run './MAKEDEV ram' from the /dev -directory. RAM disks are all major number 1, and start with minor number 0 -for /dev/ram0, etc. If used, modern kernels use /dev/ram0 for an initrd. - -The new RAM disk also has the ability to load compressed RAM disk images, -allowing one to squeeze more programs onto an average installation or -rescue floppy disk. - - -2) Kernel Command Line Parameters ---------------------------------- - - ramdisk_size=N - ============== - -This parameter tells the RAM disk driver to set up RAM disks of N k size. The -default is 4096 (4 MB) (8192 (8 MB) on S390). - - ramdisk_blocksize=N - =================== - -This parameter tells the RAM disk driver how many bytes to use per block. The -default is 1024 (BLOCK_SIZE). - - -3) Using "rdev -r" ------------------- - -The usage of the word (two bytes) that "rdev -r" sets in the kernel image is -as follows. The low 11 bits (0 -> 10) specify an offset (in 1 k blocks) of up -to 2 MB (2^11) of where to find the RAM disk (this used to be the size). Bit -14 indicates that a RAM disk is to be loaded, and bit 15 indicates whether a -prompt/wait sequence is to be given before trying to read the RAM disk. Since -the RAM disk dynamically grows as data is being written into it, a size field -is not required. Bits 11 to 13 are not currently used and may as well be zero. -These numbers are no magical secrets, as seen below: - -./arch/i386/kernel/setup.c:#define RAMDISK_IMAGE_START_MASK 0x07FF -./arch/i386/kernel/setup.c:#define RAMDISK_PROMPT_FLAG 0x8000 -./arch/i386/kernel/setup.c:#define RAMDISK_LOAD_FLAG 0x4000 - -Consider a typical two floppy disk setup, where you will have the -kernel on disk one, and have already put a RAM disk image onto disk #2. - -Hence you want to set bits 0 to 13 as 0, meaning that your RAM disk -starts at an offset of 0 kB from the beginning of the floppy. -The command line equivalent is: "ramdisk_start=0" - -You want bit 14 as one, indicating that a RAM disk is to be loaded. -The command line equivalent is: "load_ramdisk=1" - -You want bit 15 as one, indicating that you want a prompt/keypress -sequence so that you have a chance to switch floppy disks. -The command line equivalent is: "prompt_ramdisk=1" - -Putting that together gives 2^15 + 2^14 + 0 = 49152 for an rdev word. -So to create disk one of the set, you would do: - - /usr/src/linux# cat arch/i386/boot/zImage > /dev/fd0 - /usr/src/linux# rdev /dev/fd0 /dev/fd0 - /usr/src/linux# rdev -r /dev/fd0 49152 - -If you make a boot disk that has LILO, then for the above, you would use: - append = "ramdisk_start=0 load_ramdisk=1 prompt_ramdisk=1" -Since the default start = 0 and the default prompt = 1, you could use: - append = "load_ramdisk=1" - - -4) An Example of Creating a Compressed RAM Disk ----------------------------------------------- - -To create a RAM disk image, you will need a spare block device to -construct it on. This can be the RAM disk device itself, or an -unused disk partition (such as an unmounted swap partition). For this -example, we will use the RAM disk device, "/dev/ram0". - -Note: This technique should not be done on a machine with less than 8 MB -of RAM. If using a spare disk partition instead of /dev/ram0, then this -restriction does not apply. - -a) Decide on the RAM disk size that you want. Say 2 MB for this example. - Create it by writing to the RAM disk device. (This step is not currently - required, but may be in the future.) It is wise to zero out the - area (esp. for disks) so that maximal compression is achieved for - the unused blocks of the image that you are about to create. - - dd if=/dev/zero of=/dev/ram0 bs=1k count=2048 - -b) Make a filesystem on it. Say ext2fs for this example. - - mke2fs -vm0 /dev/ram0 2048 - -c) Mount it, copy the files you want to it (eg: /etc/* /dev/* ...) - and unmount it again. - -d) Compress the contents of the RAM disk. The level of compression - will be approximately 50% of the space used by the files. Unused - space on the RAM disk will compress to almost nothing. - - dd if=/dev/ram0 bs=1k count=2048 | gzip -v9 > /tmp/ram_image.gz - -e) Put the kernel onto the floppy - - dd if=zImage of=/dev/fd0 bs=1k - -f) Put the RAM disk image onto the floppy, after the kernel. Use an offset - that is slightly larger than the kernel, so that you can put another - (possibly larger) kernel onto the same floppy later without overlapping - the RAM disk image. An offset of 400 kB for kernels about 350 kB in - size would be reasonable. Make sure offset+size of ram_image.gz is - not larger than the total space on your floppy (usually 1440 kB). - - dd if=/tmp/ram_image.gz of=/dev/fd0 bs=1k seek=400 - -g) Use "rdev" to set the boot device, RAM disk offset, prompt flag, etc. - For prompt_ramdisk=1, load_ramdisk=1, ramdisk_start=400, one would - have 2^15 + 2^14 + 400 = 49552. - - rdev /dev/fd0 /dev/fd0 - rdev -r /dev/fd0 49552 - -That is it. You now have your boot/root compressed RAM disk floppy.

It does not support +products previous to the Intelliport II. + +This driver was developed on the v2.0.x Linux tree and has been tested up +to v2.4.14; it will probably not work with earlier v1.X kernels,. + + +2. QUICK INSTALLATION + +Hardware - If you have an ISA card, find a free interrupt and io port. + List those in use with `cat /proc/interrupts` and + `cat /proc/ioports`. Set the card dip switches to a free + address. You may need to configure your BIOS to reserve an + irq for an ISA card. PCI and EISA parameters are set + automagically. Insert card into computer with the power off + before or after drivers installation. + + Note the hardware address from the Computone ISA cards installed into + the system. These are required for editing ip2.c or editing + /etc/modprobe.conf, or for specification on the modprobe + command line. + + Note that the /etc/modules.conf should be used for older (pre-2.6) + kernels. + +Software - + +Module installation: + +a) Determine free irq/address to use if any (configure BIOS if need be) +b) Run "make config" or "make menuconfig" or "make xconfig" + Select (m) module for CONFIG_COMPUTONE under character + devices. CONFIG_PCI and CONFIG_MODULES also may need to be set. +c) Set address on ISA cards then: + edit /usr/src/linux/drivers/char/ip2.c if needed + or + edit /etc/modprobe.conf if needed (module). + or both to match this setting. +d) Run "make modules" +e) Run "make modules_install" +f) Run "/sbin/depmod -a" +g) install driver using `modprobe ip2 ` (options listed below) +h) run ip2mkdev (either the script below or the binary version) + + +Kernel installation: + +a) Determine free irq/address to use if any (configure BIOS if need be) +b) Run "make config" or "make menuconfig" or "make xconfig" + Select (y) kernel for CONFIG_COMPUTONE under character + devices. CONFIG_PCI may need to be set if you have PCI bus. +c) Set address on ISA cards then: + edit /usr/src/linux/drivers/char/ip2.c + (Optional - may be specified on kernel command line now) +d) Run "make zImage" or whatever target you prefer. +e) mv /usr/src/linux/arch/i386/boot/zImage to /boot. +f) Add new config for this kernel into /etc/lilo.conf, run "lilo" + or copy to a floppy disk and boot from that floppy disk. +g) Reboot using this kernel +h) run ip2mkdev (either the script below or the binary version) + +Kernel command line options: + +When compiling the driver into the kernel, io and irq may be +compiled into the driver by editing ip2.c and setting the values for +io and irq in the appropriate array. An alternative is to specify +a command line parameter to the kernel at boot up. + + ip2=io0,irq0,io1,irq1,io2,irq2,io3,irq3 + +Note that this order is very different from the specifications for the +modload parameters which have separate IRQ and IO specifiers. + +The io port also selects PCI (1) and EISA (2) boards. + + io=0 No board + io=1 PCI board + io=2 EISA board + else ISA board io address + +You only need to specify the boards which are present. + + Examples: + + 2 PCI boards: + + ip2=1,0,1,0 + + 1 ISA board at 0x310 irq 5: + + ip2=0x310,5 + +This can be added to and "append" option in lilo.conf similar to this: + + append="ip2=1,0,1,0" + + +3. INSTALLATION + +Previously, the driver sources were packaged with a set of patch files +to update the character drivers' makefile and configuration file, and other +kernel source files. A build script (ip2build) was included which applies +the patches if needed, and build any utilities needed. +What you receive may be a single patch file in conventional kernel +patch format build script. That form can also be applied by +running patch -p1 < ThePatchFile. Otherwise run ip2build. + +The driver can be installed as a module (recommended) or built into the +kernel. This is selected as for other drivers through the `make config` +command from the root of the Linux source tree. If the driver is built +into the kernel you will need to edit the file ip2.c to match the boards +you are installing. See that file for instructions. If the driver is +installed as a module the configuration can also be specified on the +modprobe command line as follows: + + modprobe ip2 irq=irq1,irq2,irq3,irq4 io=addr1,addr2,addr3,addr4 + +where irqnum is one of the valid Intelliport II interrupts (3,4,5,7,10,11, +12,15) and addr1-4 are the base addresses for up to four controllers. If +the irqs are not specified the driver uses the default in ip2.c (which +selects polled mode). If no base addresses are specified the defaults in +ip2.c are used. If you are autoloading the driver module with kerneld or +kmod the base addresses and interrupt number must also be set in ip2.c +and recompile or just insert and options line in /etc/modprobe.conf or both. +The options line is equivalent to the command line and takes precedence over +what is in ip2.c. + +/etc/modprobe.conf sample: + options ip2 io=1,0x328 irq=1,10 + alias char-major-71 ip2 + alias char-major-72 ip2 + alias char-major-73 ip2 + +The equivalent in ip2.c: + +static int io[IP2_MAX_BOARDS]= { 1, 0x328, 0, 0 }; +static int irq[IP2_MAX_BOARDS] = { 1, 10, -1, -1 }; + +The equivalent for the kernel command line (in lilo.conf): + + append="ip2=1,1,0x328,10" + + +Note: Both io and irq should be updated to reflect YOUR system. An "io" + address of 1 or 2 indicates a PCI or EISA card in the board table. + The PCI or EISA irq will be assigned automatically. + +Specifying an invalid or in-use irq will default the driver into +running in polled mode for that card. If all irq entries are 0 then +all cards will operate in polled mode. + +If you select the driver as part of the kernel run : + + make zlilo (or whatever you do to create a bootable kernel) + +If you selected a module run : + + make modules && make modules_install + +The utility ip2mkdev (see 5 and 7 below) creates all the device nodes +required by the driver. For a device to be created it must be configured +in the driver and the board must be installed. Only devices corresponding +to real IntelliPort II ports are created. With multiple boards and expansion +boxes this will leave gaps in the sequence of device names. ip2mkdev uses +Linux tty naming conventions: ttyF0 - ttyF255 for normal devices, and +cuf0 - cuf255 for callout devices. + + +4. USING THE DRIVERS + +As noted above, the driver implements the ports in accordance with Linux +conventions, and the devices should be interchangeable with the standard +serial devices. (This is a key point for problem reporting: please make +sure that what you are trying do works on the ttySx/cuax ports first; then +tell us what went wrong with the ip2 ports!) + +Higher speeds can be obtained using the setserial utility which remaps +38,400 bps (extb) to 57,600 bps, 115,200 bps, or a custom speed. +Intelliport II installations using the PowerPort expansion module can +use the custom speed setting to select the highest speeds: 153,600 bps, +230,400 bps, 307,200 bps, 460,800bps and 921,600 bps. The base for +custom baud rate configuration is fixed at 921,600 for cards/expansion +modules with ST654's and 115200 for those with Cirrus CD1400's. This +corresponds to the maximum bit rates those chips are capable. +For example if the baud base is 921600 and the baud divisor is 18 then +the custom rate is 921600/18 = 51200 bps. See the setserial man page for +complete details. Of course if stty accepts the higher rates now you can +use that as well as the standard ioctls(). + + +5. ip2mkdev and assorted utilities... + +Several utilities, including the source for a binary ip2mkdev utility are +available under .../drivers/char/ip2. These can be build by changing to +that directory and typing "make" after the kernel has be built. If you do +not wish to compile the binary utilities, the shell script below can be +cut out and run as "ip2mkdev" to create the necessary device files. To +use the ip2mkdev script, you must have procfs enabled and the proc file +system mounted on /proc. + + +6. NOTES + +This is a release version of the driver, but it is impossible to test it +in all configurations of Linux. If there is any anomalous behaviour that +does not match the standard serial port's behaviour please let us know. + + +7. ip2mkdev shell script + +Previously, this script was simply attached here. It is now attached as a +shar archive to make it easier to extract the script from the documentation. +To create the ip2mkdev shell script change to a convenient directory (/tmp +works just fine) and run the following command: + + unshar Documentation/serial/computone.txt + (This file) + +You should now have a file ip2mkdev in your current working directory with +permissions set to execute.

Their support +has enabled me to provide enhancements to the driver. + +Please report your experiences with this driver to me (arobinso@nyx.net). I +am looking for both positive and negative feedback. + +*** IMPORTANT CHANGES FOR 2.1 *** +Support for PIO mode. Five situations will cause PIO mode to be used: +1) A multiport card is detected. PIO mode will always be used. (8 port cards +do not support DMA). +2) The DMA channel is set to an invalid value (anything other than 1 or 3). +3) The DMA buffer/channel could not be allocated. The port will revert to PIO +mode until it is reopened. +4) Less than a specified number of bytes need to be transferred to/from the +FIFOs. PIO mode will be used for that transfer only. +5) A port needs to do a DMA transfer and another port is already using the +DMA channel. PIO mode will be used for that transfer only. + +Since the Hayes ESP seems to conflict with other cards (notably sound cards) +when using DMA, DMA is turned off by default. To use DMA, it must be turned +on explicitly, either with the "dma=" option described below or with +setserial. A multiport card can be forced into DMA mode by using setserial; +however, most multiport cards don't support DMA. + +The latest version of setserial allows the enhanced configuration of the ESP +card to be viewed and modified. +*** + +This package contains the files needed to compile a module to support the Hayes +ESP card. The drivers are basically a modified version of the serial drivers. + +Features: + +- Uses the enhanced mode of the ESP card, allowing a wider range of + interrupts and features than compatibility mode +- Uses DMA and 16 bit PIO mode to transfer data to and from the ESP's FIFOs, + reducing CPU load +- Supports primary and secondary ports + + +If the driver is compiled as a module, the IRQs to use can be specified by +using the irq= option. The format is: + +irq=[0x100],[0x140],[0x180],[0x200],[0x240],[0x280],[0x300],[0x380] + +The address in brackets is the base address of the card. The IRQ of +nonexistent cards can be set to 0. If an IRQ of a card that does exist is set +to 0, the driver will attempt to guess at the correct IRQ. For example, to set +the IRQ of the card at address 0x300 to 12, the insmod command would be: + +insmod esp irq=0,0,0,0,0,0,12,0 + +The custom divisor can be set by using the divisor= option. The format is the +same as for the irq= option. Each divisor value is a series of hex digits, +with each digit representing the divisor to use for a corresponding port. The +divisor value is constructed RIGHT TO LEFT. Specifying a nonzero divisor value +will automatically set the spd_cust flag. To calculate the divisor to use for +a certain baud rate, divide the port's base baud (generally 921600) by the +desired rate. For example, to set the divisor of the primary port at 0x300 to +4 and the divisor of the secondary port at 0x308 to 8, the insmod command would +be: + +insmod esp divisor=0,0,0,0,0,0,0x84,0 + +The dma= option can be used to set the DMA channel. The channel can be either +1 or 3. Specifying any other value will force the driver to use PIO mode. +For example, to set the DMA channel to 3, the insmod command would be: + +insmod esp dma=3 + +The rx_trigger= and tx_trigger= options can be used to set the FIFO trigger +levels. They specify when the ESP card should send an interrupt. Larger +values will decrease the number of interrupts; however, a value too high may +result in data loss. Valid values are 1 through 1023, with 768 being the +default. For example, to set the receive trigger level to 512 bytes and the +transmit trigger level to 700 bytes, the insmod command would be: + +insmod esp rx_trigger=512 tx_trigger=700 + +The flow_off= and flow_on= options can be used to set the hardware flow off/ +flow on levels. The flow on level must be lower than the flow off level, and +the flow off level should be higher than rx_trigger. Valid values are 1 +through 1023, with 1016 being the default flow off level and 944 being the +default flow on level. For example, to set the flow off level to 1000 bytes +and the flow on level to 935 bytes, the insmod command would be: + +insmod esp flow_off=1000 flow_on=935 + +The rx_timeout= option can be used to set the receive timeout value. This +value indicates how long after receiving the last character that the ESP card +should wait before signalling an interrupt. Valid values are 0 though 255, +with 128 being the default. A value too high will increase latency, and a +value too low will cause unnecessary interrupts. For example, to set the +receive timeout to 255, the insmod command would be: + +insmod esp rx_timeout=255 + +The pio_threshold= option sets the threshold (in number of characters) for +using PIO mode instead of DMA mode. For example, if this value is 32, +transfers of 32 bytes or less will always use PIO mode. + +insmod esp pio_threshold=32 + +Multiple options can be listed on the insmod command line by separating each +option with a space. For example: + +insmod esp dma=3 trigger=512 + +The esp module can be automatically loaded when needed. To cause this to +happen, add the following lines to /etc/modprobe.conf (replacing the last line +with options for your configuration): + +alias char-major-57 esp +alias char-major-58 esp +options esp irq=0,0,0,0,0,0,3,0 divisor=0,0,0,0,0,0,0x4,0 + +You may also need to run 'depmod -a'. + +Devices must be created manually. To create the devices, note the output from +the module after it is inserted. The output will appear in the location where +kernel messages usually appear (usually /var/adm/messages). Create two devices +for each 'tty' mentioned, one with major of 57 and the other with major of 58. +The minor number should be the same as the tty number reported. The commands +would be (replace ? with the tty number): + +mknod /dev/ttyP? c 57 ? +mknod /dev/cup? c 58 ? + +For example, if the following line appears: + +Oct 24 18:17:23 techno kernel: ttyP8 at 0x0140 (irq = 3) is an ESP primary port + +...two devices should be created: + +mknod /dev/ttyP8 c 57 8 +mknod /dev/cup8 c 58 8 + +You may need to set the permissions on the devices: + +chmod 666 /dev/ttyP* +chmod 666 /dev/cup* + +The ESP module and the serial module should not conflict (they can be used at +the same time). After the ESP module has been loaded the ports on the ESP card +will no longer be accessible by the serial driver. + +If I/O errors are experienced when accessing the port, check for IRQ and DMA +conflicts ('cat /proc/interrupts' and 'cat /proc/dma' for a list of IRQs and +DMAs currently in use). + +Enjoy! +Andrew J.

However, if compatibility problem + occurs, please contact Moxa at support@moxa.com.tw. + + In addition to device driver, useful utilities are also provided in this + version. They are + - msdiag Diagnostic program for displaying installed Moxa + Smartio/Industio boards. + - msmon Monitor program to observe data count and line status signals. + - msterm A simple terminal program which is useful in testing serial + ports. + - io-irq.exe Configuration program to setup ISA boards. Please note that + this program can only be executed under DOS. + + All the drivers and utilities are published in form of source code under + GNU General Public License in this version. Please refer to GNU General + Public License announcement in each source code file for more detail. + + In Moxa's Web sites, you may always find latest driver at http://web.moxa.com. + + This version of driver can be installed as Loadable Module (Module driver) + or built-in into kernel (Static driver). You may refer to following + installation procedure for suitable one. Before you install the driver, + please refer to hardware installation procedure in the User's Manual. + + We assume the user should be familiar with following documents. + - Serial-HOWTO + - Kernel-HOWTO + +----------------------------------------------------------------------------- +2. System Requirement + - Hardware platform: Intel x86 machine + - Kernel version: 2.4.x or 2.6.x + - gcc version 2.72 or later + - Maximum 4 boards can be installed in combination + +----------------------------------------------------------------------------- +3. Installation + + 3.1 Hardware installation + 3.2 Driver files + 3.3 Device naming convention + 3.4 Module driver configuration + 3.5 Static driver configuration for Linux kernel 2.4.x, 2.6.x. + 3.6 Custom configuration + 3.7 Verify driver installation + + + 3.1 Hardware installation + + There are two types of buses, ISA and PCI, for Smartio/Industio + family multiport board. + + ISA board + --------- + You'll have to configure CAP address, I/O address, Interrupt Vector + as well as IRQ before installing this driver. Please refer to hardware + installation procedure in User's Manual before proceed any further. + Please make sure the JP1 is open after the ISA board is set properly. + + PCI/UPCI board + -------------- + You may need to adjust IRQ usage in BIOS to avoid from IRQ conflict + with other ISA devices. Please refer to hardware installation + procedure in User's Manual in advance. + + PCI IRQ Sharing + ----------- + Each port within the same multiport board shares the same IRQ. Up to + 4 Moxa Smartio/Industio PCI Family multiport boards can be installed + together on one system and they can share the same IRQ. + + + 3.2 Driver files + + The driver file may be obtained from ftp, CD-ROM or floppy disk. The + first step, anyway, is to copy driver file "mxser.tgz" into specified + directory. e.g. /moxa. The execute commands as below. + + # cd / + # mkdir moxa + # cd /moxa + # tar xvf /dev/fd0 + + or + + # cd / + # mkdir moxa + # cd /moxa + # cp /mnt/cdrom//mxser.tgz . + # tar xvfz mxser.tgz + + + 3.3 Device naming convention + + You may find all the driver and utilities files in /moxa/mxser. + Following installation procedure depends on the model you'd like to + run the driver. If you prefer module driver, please refer to 3.4. + If static driver is required, please refer to 3.5. + + Dialin and callout port + ----------------------- + This driver remains traditional serial device properties. There are + two special file name for each serial port. One is dial-in port + which is named "ttyMxx". For callout port, the naming convention + is "cumxx". + + Device naming when more than 2 boards installed + ----------------------------------------------- + Naming convention for each Smartio/Industio multiport board is + pre-defined as below. + + Board Num. Dial-in Port Callout port + 1st board ttyM0 - ttyM7 cum0 - cum7 + 2nd board ttyM8 - ttyM15 cum8 - cum15 + 3rd board ttyM16 - ttyM23 cum16 - cum23 + 4th board ttyM24 - ttym31 cum24 - cum31 + + + !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! + Under Kernel 2.6 the cum Device is Obsolete. So use ttyM* + device instead. + !!!!!!!!!!!!!!!!!!!! NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! + + Board sequence + -------------- + This driver will activate ISA boards according to the parameter set + in the driver. After all specified ISA board activated, PCI board + will be installed in the system automatically driven. + Therefore the board number is sorted by the CAP address of ISA boards. + For PCI boards, their sequence will be after ISA boards and C168H/PCI + has higher priority than C104H/PCI boards. + + 3.4 Module driver configuration + Module driver is easiest way to install. If you prefer static driver + installation, please skip this paragraph. + + + ------------- Prepare to use the MOXA driver-------------------- + 3.4.1 Create tty device with correct major number + Before using MOXA driver, your system must have the tty devices + which are created with driver's major number. We offer one shell + script "msmknod" to simplify the procedure. + This step is only needed to be executed once. But you still + need to do this procedure when: + a. You change the driver's major number. Please refer the "3.7" + section. + b. Your total installed MOXA boards number is changed. Maybe you + add/delete one MOXA board. + c. You want to change the tty name. This needs to modify the + shell script "msmknod" + + The procedure is: + # cd /moxa/mxser/driver + # ./msmknod + + This shell script will require the major number for dial-in + device and callout device to create tty device. You also need + to specify the total installed MOXA board number. Default major + numbers for dial-in device and callout device are 30, 35. If + you need to change to other number, please refer section "3.7" + for more detailed procedure. + Msmknod will delete any special files occupying the same device + naming. + + 3.4.2 Build the MOXA driver and utilities + Before using the MOXA driver and utilities, you need compile the + all the source code. This step is only need to be executed once. + But you still re-compile the source code if you modify the source + code. For example, if you change the driver's major number (see + "3.7" section), then you need to do this step again. + + Find "Makefile" in /moxa/mxser, then run + + # make clean; make install + + !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!! + For Red Hat 9, Red Hat Enterprise Linux AS3/ES3/WS3 & Fedora Core1: + # make clean; make installsp1 + + For Red Hat Enterprise Linux AS4/ES4/WS4: + # make clean; make installsp2 + !!!!!!!!!! NOTE !!!!!!!!!!!!!!!!! + + The driver files "mxser.o" and utilities will be properly compiled + and copied to system directories respectively. + + ------------- Load MOXA driver-------------------- + 3.4.3 Load the MOXA driver + + # modprobe mxser + + will activate the module driver. You may run "lsmod" to check + if "mxser" is activated. If the MOXA board is ISA board, the + is needed. Please refer to section "3.4.5" for more + information. + + + ------------- Load MOXA driver on boot -------------------- + 3.4.4 For the above description, you may manually execute + "modprobe mxser" to activate this driver and run + "rmmod mxser" to remove it. + However, it's better to have a boot time configuration to + eliminate manual operation. Boot time configuration can be + achieved by rc file. We offer one "rc.mxser" file to simplify + the procedure under "moxa/mxser/driver". + + But if you use ISA board, please modify the "modprobe ..." command + to add the argument (see "3.4.5" section). After modifying the + rc.mxser, please try to execute "/moxa/mxser/driver/rc.mxser" + manually to make sure the modification is ok. If any error + encountered, please try to modify again. If the modification is + completed, follow the below step. + + Run following command for setting rc files. + + # cd /moxa/mxser/driver + # cp ./rc.mxser /etc/rc.d + # cd /etc/rc.d + + Check "rc.serial" is existed or not. If "rc.serial" doesn't exist, + create it by vi, run "chmod 755 rc.serial" to change the permission. + Add "/etc/rc.d/rc.mxser" in last line, + + Reboot and check if moxa.o activated by "lsmod" command. + + 3.4.5. If you'd like to drive Smartio/Industio ISA boards in the system, + you'll have to add parameter to specify CAP address of given + board while activating "mxser.o". The format for parameters are + as follows. + + modprobe mxser ioaddr=0x???,0x???,0x???,0x??? + | | | | + | | | +- 4th ISA board + | | +------ 3rd ISA board + | +------------ 2nd ISA board + +------------------- 1st ISA board + + 3.5 Static driver configuration for Linux kernel 2.4.x and 2.6.x + + Note: To use static driver, you must install the linux kernel + source package. + + 3.5.1 Backup the built-in driver in the kernel. + # cd /usr/src/linux/drivers/char + # mv mxser.c mxser.c.old + + For Red Hat 7.x user, you need to create link: + # cd /usr/src + # ln -s linux-2.4 linux + + 3.5.2 Create link + # cd /usr/src/linux/drivers/char + # ln -s /moxa/mxser/driver/mxser.c mxser.c + + 3.5.3 Add CAP address list for ISA boards. For PCI boards user, + please skip this step. + + In module mode, the CAP address for ISA board is given by + parameter. In static driver configuration, you'll have to + assign it within driver's source code. If you will not + install any ISA boards, you may skip to next portion. + The instructions to modify driver source code are as + below. + a. # cd /moxa/mxser/driver + # vi mxser.c + b. Find the array mxserBoardCAP[] as below. + + static int mxserBoardCAP[] + = {0x00, 0x00, 0x00, 0x00}; + + c. Change the address within this array using vi. For + example, to driver 2 ISA boards with CAP address + 0x280 and 0x180 as 1st and 2nd board. Just to change + the source code as follows. + + static int mxserBoardCAP[] + = {0x280, 0x180, 0x00, 0x00}; + + 3.5.4 Setup kernel configuration + + Configure the kernel: + + # cd /usr/src/linux + # make menuconfig + + You will go into a menu-driven system. Please select [Character + devices][Non-standard serial port support], enable the [Moxa + SmartIO support] driver with "[*]" for built-in (not "[M]"), then + select [Exit] to exit this program. + + 3.5.5 Rebuild kernel + The following are for Linux kernel rebuilding, for your + reference only. + For appropriate details, please refer to the Linux document. + + a. cd /usr/src/linux + b. make clean /* take a few minutes */ + c. make dep /* take a few minutes */ + d. make bzImage /* take probably 10-20 minutes */ + e. make install /* copy boot image to correct position */ + f. Please make sure the boot kernel (vmlinuz) is in the + correct position. + g. If you use 'lilo' utility, you should check /etc/lilo.conf + 'image' item specified the path which is the 'vmlinuz' path, + or you will load wrong (or old) boot kernel image (vmlinuz). + After checking /etc/lilo.conf, please run "lilo". + + Note that if the result of "make bzImage" is ERROR, then you have to + go back to Linux configuration Setup. Type "make menuconfig" in + directory /usr/src/linux. + + + 3.5.6 Make tty device and special file + # cd /moxa/mxser/driver + # ./msmknod + + 3.5.7 Make utility + # cd /moxa/mxser/utility + # make clean; make install + + 3.5.8 Reboot + + + + 3.6 Custom configuration + Although this driver already provides you default configuration, you + still can change the device name and major number. The instruction to + change these parameters are shown as below. + + Change Device name + ------------------ + If you'd like to use other device names instead of default naming + convention, all you have to do is to modify the internal code + within the shell script "msmknod". First, you have to open "msmknod" + by vi. Locate each line contains "ttyM" and "cum" and change them + to the device name you desired. "msmknod" creates the device names + you need next time executed. + + Change Major number + ------------------- + If major number 30 and 35 had been occupied, you may have to select + 2 free major numbers for this driver. There are 3 steps to change + major numbers. + + 3.6.1 Find free major numbers + In /proc/devices, you may find all the major numbers occupied + in the system. Please select 2 major numbers that are available. + e.g. 40, 45. + 3.6.2 Create special files + Run /moxa/mxser/driver/msmknod to create special files with + specified major numbers. + 3.6.3 Modify driver with new major number + Run vi to open /moxa/mxser/driver/mxser.c. Locate the line + contains "MXSERMAJOR". Change the content as below. + #define MXSERMAJOR 40 + #define MXSERCUMAJOR 45 + 3.6.4 Run "make clean; make install" in /moxa/mxser/driver. + + 3.7 Verify driver installation + You may refer to /var/log/messages to check the latest status + log reported by this driver whenever it's activated. + +----------------------------------------------------------------------------- +4. Utilities + There are 3 utilities contained in this driver. They are msdiag, msmon and + msterm. These 3 utilities are released in form of source code. They should + be compiled into executable file and copied into /usr/bin. + + Before using these utilities, please load driver (refer 3.4 & 3.5) and + make sure you had run the "msmknod" utility. + + msdiag - Diagnostic + -------------------- + This utility provides the function to display what Moxa Smartio/Industio + board found by driver in the system. + + msmon - Port Monitoring + ----------------------- + This utility gives the user a quick view about all the MOXA ports' + activities. One can easily learn each port's total received/transmitted + (Rx/Tx) character count since the time when the monitoring is started. + Rx/Tx throughputs per second are also reported in interval basis (e.g. + the last 5 seconds) and in average basis (since the time the monitoring + is started). You can reset all ports' count by key. <+> <-> + (plus/minus) keys to change the displaying time interval. Press + on the port, that cursor stay, to view the port's communication + parameters, signal status, and input/output queue. + + msterm - Terminal Emulation + --------------------------- + This utility provides data sending and receiving ability of all tty ports, + especially for MOXA ports. It is quite useful for testing simple + application, for example, sending AT command to a modem connected to the + port or used as a terminal for login purpose. Note that this is only a + dumb terminal emulation without handling full screen operation. + +----------------------------------------------------------------------------- +5.

These boards provide, 2, 4, 8, 16, or 32 +high-speed serial ports or modems. This driver supports up to a combination +of four RocketPort or RocketModems boards in one machine simultaneously. +This file assumes that you are using the RocketPort driver which is +integrated into the kernel sources. + +The driver can also be installed as an external module using the usual +"make;make install" routine. This external module driver, obtainable +from the Comtrol website listed below, is useful for updating the driver +or installing it into kernels which do not have the driver configured +into them. Installations instructions for the external module +are in the included README and HW_INSTALL files. + +RocketPort ISA and RocketModem II PCI boards currently are only supported by +this driver in module form. + +The RocketPort ISA board requires I/O ports to be configured by the DIP +switches on the board. See the section "ISA Rocketport Boards" below for +information on how to set the DIP switches. + +You pass the I/O port to the driver using the following module parameters: + +board1 : I/O port for the first ISA board +board2 : I/O port for the second ISA board +board3 : I/O port for the third ISA board +board4 : I/O port for the fourth ISA board + +There is a set of utilities and scripts provided with the external driver +( downloadable from http://www.comtrol.com ) that ease the configuration and +setup of the ISA cards. + +The RocketModem II PCI boards require firmware to be loaded into the card +before it will function. The driver has only been tested as a module for this +board. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- + +INSTALLATION PROCEDURES +----------------------- + +RocketPort/RocketModem PCI cards require no driver configuration, they are +automatically detected and configured. + +The RocketPort driver can be installed as a module (recommended) or built +into the kernel. This is selected, as for other drivers, through the `make config` +command from the root of the Linux source tree during the kernel build process. + +The RocketPort/RocketModem serial ports installed by this driver are assigned +device major number 46, and will be named /dev/ttyRx, where x is the port number +starting at zero (ex. /dev/ttyR0, /devttyR1, ...). If you have multiple cards +installed in the system, the mapping of port names to serial ports is displayed +in the system log at /var/log/messages. + +If installed as a module, the module must be loaded. This can be done +manually by entering "modprobe rocket". To have the module loaded automatically +upon system boot, edit the /etc/modprobe.conf file and add the line +"alias char-major-46 rocket". + +In order to use the ports, their device names (nodes) must be created with mknod. +This is only required once, the system will retain the names once created. To +create the RocketPort/RocketModem device names, use the command +"mknod /dev/ttyRx c 46 x" where x is the port number starting at zero. For example: + +>mknod /dev/ttyR0 c 46 0 +>mknod /dev/ttyR1 c 46 1 +>mknod /dev/ttyR2 c 46 2 + +The Linux script MAKEDEV will create the first 16 ttyRx device names (nodes) +for you: + +>/dev/MAKEDEV ttyR + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- + +ISA Rocketport Boards +--------------------- + +You must assign and configure the I/O addresses used by the ISA Rocketport +card before installing and using it. This is done by setting a set of DIP +switches on the Rocketport board. + + +SETTING THE I/O ADDRESS +----------------------- + +Before installing RocketPort(R) or RocketPort RA boards, you must find +a range of I/O addresses for it to use. The first RocketPort card +requires a 68-byte contiguous block of I/O addresses, starting at one +of the following: 0x100h, 0x140h, 0x180h, 0x200h, 0x240h, 0x280h, +0x300h, 0x340h, 0x380h. This I/O address must be reflected in the DIP +switches of *all* of the Rocketport cards. + +The second, third, and fourth RocketPort cards require a 64-byte +contiguous block of I/O addresses, starting at one of the following +I/O addresses: 0x100h, 0x140h, 0x180h, 0x1C0h, 0x200h, 0x240h, 0x280h, +0x2C0h, 0x300h, 0x340h, 0x380h, 0x3C0h. The I/O address used by the +second, third, and fourth Rocketport cards (if present) are set via +software control. The DIP switch settings for the I/O address must be +set to the value of the first Rocketport cards. + +In order to distinguish each of the card from the others, each card +must have a unique board ID set on the dip switches. The first +Rocketport board must be set with the DIP switches corresponding to +the first board, the second board must be set with the DIP switches +corresponding to the second board, etc. IMPORTANT: The board ID is +the only place where the DIP switch settings should differ between the +various Rocketport boards in a system. + +The I/O address range used by any of the RocketPort cards must not +conflict with any other cards in the system, including other +RocketPort cards. Below, you will find a list of commonly used I/O +address ranges which may be in use by other devices in your system. +On a Linux system, "cat /proc/ioports" will also be helpful in +identifying what I/O addresses are being used by devices on your +system. + +Remember, the FIRST RocketPort uses 68 I/O addresses. So, if you set it +for 0x100, it will occupy 0x100 to 0x143. This would mean that you +CAN NOT set the second, third or fourth board for address 0x140 since +the first 4 bytes of that range are used by the first board. You would +need to set the second, third, or fourth board to one of the next available +blocks such as 0x180. + +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- + +RocketPort and RocketPort RA SW1 Settings: + + +-------------------------------+ + | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | + +-------+-------+---------------+ + | Unused| Card | I/O Port Block| + +-------------------------------+ + +DIP Switches DIP Switches +7 8 6 5 +=================== =================== +On On UNUSED, MUST BE ON.

I +haven't the foggiest why. My Specialix card is now at 0x180. My +other computer runs just fine with the Specialix card at 0x100.... +The card occupies 4 addresses, but actually only two are really used. + +The PCI version doesn't have any dip switches. The BIOS assigns +an IO address. + +The driver now still autoprobes at 0x100, 0x180, 0x250 and 0x260. If +that causes trouble for you, please report that. I'll remove +autoprobing then. + +The driver will tell the card what IRQ to use, so you don't have to +change any jumpers to change the IRQ. Just use a command line +argument (irq=xx) to the insmod program to set the interrupt. + +The BIOS assigns the IRQ on the PCI version. You have no say in what +IRQ to use in that case. + +If your specialix cards are not at the default locations, you can use +the kernel command line argument "specialix=io0,irq0,io1,irq1...". +Here "io0" is the io address for the first card, and "irq0" is the +irq line that the first card should use. And so on. + +Examples. + +You use the driver as a module and have three cards at 0x100, 0x250 +and 0x180. And some way or another you want them detected in that +order. Moreover irq 12 is taken (e.g. by your PS/2 mouse). + + insmod specialix.o iobase=0x100,0x250,0x180 irq=9,11,15 + +The same three cards, but now in the kernel would require you to +add + + specialix=0x100,9,0x250,11,0x180,15 + +to the command line. This would become + + append="specialix=0x100,9,0x250,11,0x180,15" + +in your /etc/lilo.conf file if you use lilo. + +The Specialix driver is slightly odd: It allows you to have the second +or third card detected without having a first card. This has +advantages and disadvantages. A slot that isn't filled by an ISA card, +might be filled if a PCI card is detected. Thus if you have an ISA +card at 0x250 and a PCI card, you would get: + +sx0: specialix IO8+ Board at 0x100 not found. +sx1: specialix IO8+ Board at 0x180 not found. +sx2: specialix IO8+ board detected at 0x250, IRQ 12, CD1865 Rev. B. +sx3: specialix IO8+ Board at 0x260 not found. +sx0: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B. + +This would happen if you don't give any probe hints to the driver. +If you would specify: + + specialix=0x250,11 + +you'd get the following messages: + +sx0: specialix IO8+ board detected at 0x250, IRQ 11, CD1865 Rev. B. +sx1: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B. + +ISA probing is aborted after the IO address you gave is exhausted, and +the PCI card is now detected as the second card. The ISA card is now +also forced to IRQ11.... + + +Baud rates +========== + +The rev 1.2 and below boards use a CL-CD1864. These chips can only +do 64kbit. The rev 1.3 and newer boards use a CL-CD1865. These chips +are officially capable of 115k2. + +The Specialix card uses a 25MHz crystal (in times two mode, which in +fact is a divided by two mode). This is not enough to reach the rated +115k2 on all ports at the same time. With this clock rate you can only +do 37% of this rate. This means that at 115k2 on all ports you are +going to lose characters (The chip cannot handle that many incoming +bits at this clock rate.) (Yes, you read that correctly: there is a +limit to the number of -=bits=- per second that the chip can handle.) + +If you near the "limit" you will first start to see a graceful +degradation in that the chip cannot keep the transmitter busy at all +times. However with a central clock this slow, you can also get it to +miss incoming characters. The driver will print a warning message when +you are outside the official specs. The messages usually show up in +the file /var/log/messages . + +The specialix card cannot reliably do 115k2. If you use it, you have +to do "extensive testing" (*) to verify if it actually works. + +When "mgetty" communicates with my modem at 115k2 it reports: +got: +++[0d]ATQ0V1H0[0d][0d][8a]O[cb][0d][8a] + ^^^^ ^^^^ ^^^^ + +The three characters that have the "^^^" under them have suffered a +bit error in the highest bit. In conclusion: I've tested it, and found +that it simply DOESN'T work for me. I also suspect that this is also +caused by the baud rate being just a little bit out of tune. + +I upgraded the crystal to 66Mhz on one of my Specialix cards. Works +great! Contact me for details.

The default +behaviour is specialix.sx_rtscts = 0 where the pin behaves as DTR when +hardware handshaking is off. It behaves as the RTS hardware +handshaking signal when hardware handshaking is selected. + +When you use this, you have to use the appropriate cable. The +cable will either be compatible with hardware handshaking or with +software handshaking. So switching on the fly is not really an +option. + +I actually prefer to use the "specialix.sx_rtscts=1" option. +This makes the DTR/RTS pin always an RTS pin, and ioctls to +change DTR are always ignored. I have a cable that is configured +for this. + + +Ports and devices +================= + +Port 0 is the one furthest from the card-edge connector. + +Devices: + +You should make the devices as follows: + +bash +cd /dev +for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 \ + 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 +do + echo -n "$i " + mknod /dev/ttyW$i c 75 $i + mknod /dev/cuw$i c 76 $i +done +echo "" + +If your system doesn't come with these devices preinstalled, bug your +linux-vendor about this. They have had ample time to get this +implemented by now. + +You cannot have more than 4 boards in one computer. The card only +supports 4 different interrupts. If you really want this, contact me +about this and I'll give you a few tips (requires soldering iron).... + +If you have enough PCI slots, you can probably use more than 4 PCI +versions of the card though.... + +The PCI version of the card cannot adhere to the mechanical part of +the PCI spec because the 8 serial connectors are simply too large. If +it doesn't fit in your computer, bring back the card. + + +------------------------------------------------------------------------ + + + Fixed bugs and restrictions: + - During initialization, interrupts are blindly turned on. + Having a shadow variable would cause an extra memory + access on every IO instruction. + - The interrupt (on the card) should be disabled when we + don't allocate the Linux end of the interrupt. This allows + a different driver/card to use it while all ports are not in + use..... (a la standard serial port) + == An extra _off variant of the sx_in and sx_out macros are + now available.

Neat! + - Can you set the IO address from the lilo command line? + If you need this, bug me about it, I'll make it. + == Hah! No bugging needed. Fixed! :-) + - Cirrus logic hasn't gotten back to me yet why the CD1865 can + and the CD1864 can't do 115k2. I suspect that this is + because the CD1864 is not rated for 33MHz operation. + Therefore the CD1864 versions of the card can't do 115k2 on + all ports just like the CD1865 versions. The driver does + not block 115k2 on CD1864 cards. + == I called the Cirrus Logic representative here in Holland. + The CD1864 databook is identical to the CD1865 databook, + except for an extra warning at the end. Similar Bit errors + have been observed in testing at 115k2 on both an 1865 and + a 1864 chip. I see no reason why I would prohibit 115k2 on + 1864 chips and not do it on 1865 chips. Actually there is + reason to prohibit it on BOTH chips. I print a warning. + If you use 115k2, you're on your own. + - A spiky CD may send spurious HUPs.

INTRODUCTION + +There are two drivers that work with the different families of Stallion +multiport serial boards. One is for the Stallion smart boards - that is +EasyIO, EasyConnection 8/32 and EasyConnection 8/64-PCI, the other for +the true Stallion intelligent multiport boards - EasyConnection 8/64 +(ISA, EISA, MCA), EasyConnection/RA-PCI, ONboard and Brumby. + +If you are using any of the Stallion intelligent multiport boards (Brumby, +ONboard, EasyConnection 8/64 (ISA, EISA, MCA), EasyConnection/RA-PCI) with +Linux you will need to get the driver utility package. This contains a +firmware loader and the firmware images necessary to make the devices operate. + +The Stallion Technologies ftp site, ftp.stallion.com, will always have +the latest version of the driver utility package. + +ftp://ftp.stallion.com/drivers/ata5/Linux/ata-linux-550.tar.gz + +As of the printing of this document the latest version of the driver +utility package is 5.5.0. If a later version is now available then you +should use the latest version. + +If you are using the EasyIO, EasyConnection 8/32 or EasyConnection 8/64-PCI +boards then you don't need this package, although it does have a serial stats +display program. + +If you require DIP switch settings, EISA or MCA configuration files, or any +other information related to Stallion boards then have a look at Stallion's +web pages at http://www.stallion.com. + + + +2. INSTALLATION + +The drivers can be used as loadable modules or compiled into the kernel. +You can choose which when doing a "config" on the kernel. + +All ISA, EISA and MCA boards that you want to use need to be configured into +the driver(s). All PCI boards will be automatically detected when you load +the driver - so they do not need to be entered into the driver(s) +configuration structure. Note that kernel PCI support is required to use PCI +boards. + +There are two methods of configuring ISA, EISA and MCA boards into the drivers. +If using the driver as a loadable module then the simplest method is to pass +the driver configuration as module arguments. The other method is to modify +the driver source to add configuration lines for each board in use. + +If you have pre-built Stallion driver modules then the module argument +configuration method should be used. A lot of Linux distributions come with +pre-built driver modules in /lib/modules/X.Y.Z/misc for the kernel in use. +That makes things pretty simple to get going. + + +2.1 MODULE DRIVER CONFIGURATION: + +The simplest configuration for modules is to use the module load arguments +to configure any ISA, EISA or MCA boards. PCI boards are automatically +detected, so do not need any additional configuration at all. + +If using EasyIO, EasyConnection 8/32 ISA or MCA, or EasyConnection 8/63-PCI +boards then use the "stallion" driver module, Otherwise if you are using +an EasyConnection 8/64 ISA, EISA or MCA, EasyConnection/RA-PCI, ONboard, +Brumby or original Stallion board then use the "istallion" driver module. + +Typically to load up the smart board driver use: + + modprobe stallion + +This will load the EasyIO and EasyConnection 8/32 driver. It will output a +message to say that it loaded and print the driver version number. It will +also print out whether it found the configured boards or not. These messages +may not appear on the console, but typically are always logged to +/var/adm/messages or /var/log/syslog files - depending on how the klogd and +syslogd daemons are setup on your system. + +To load the intelligent board driver use: + + modprobe istallion + +It will output similar messages to the smart board driver. + +If not using an auto-detectable board type (that is a PCI board) then you +will also need to supply command line arguments to the modprobe command +when loading the driver. The general form of the configuration argument is + + board?=[,[,][,]] + +where: + + board? -- specifies the arbitrary board number of this board, + can be in the range 0 to 3. + + name -- textual name of this board. The board name is the common + board name, or any "shortened" version of that. The board + type number may also be used here. + + ioaddr -- specifies the I/O address of this board. This argument is + optional, but should generally be specified. + + addr -- optional second address argument. Some board types require + a second I/O address, some require a memory address. The + exact meaning of this argument depends on the board type. + + irq -- optional IRQ line used by this board. + +Up to 4 board configuration arguments can be specified on the load line. +Here is some examples: + + modprobe stallion board0=easyio,0x2a0,5 + +This configures an EasyIO board as board 0 at I/O address 0x2a0 and IRQ 5. + + modprobe istallion board3=ec8/64,0x2c0,0xcc000 + +This configures an EasyConnection 8/64 ISA as board 3 at I/O address 0x2c0 at +memory address 0xcc000. + + modprobe stallion board1=ec8/32-at,0x2a0,0x280,10 + +This configures an EasyConnection 8/32 ISA board at primary I/O address 0x2a0, +secondary address 0x280 and IRQ 10. + +You will probably want to enter this module load and configuration information +into your system startup scripts so that the drivers are loaded and configured +on each system boot. Typically the start up script would be something like +/etc/modprobe.conf. + + +2.2 STATIC DRIVER CONFIGURATION: + +For static driver configuration you need to modify the driver source code. +Entering ISA, EISA and MCA boards into the driver(s) configuration structure +involves editing the driver(s) source file. It's pretty easy if you follow +the instructions below. Both drivers can support up to 4 boards. The smart +card driver (the stallion.c driver) supports any combination of EasyIO and +EasyConnection 8/32 boards (up to a total of 4). The intelligent driver +supports any combination of ONboards, Brumbys, Stallions and EasyConnection +8/64 (ISA and EISA) boards (up to a total of 4). + +To set up the driver(s) for the boards that you want to use you need to +edit the appropriate driver file and add configuration entries. + +If using EasyIO or EasyConnection 8/32 ISA or MCA boards, + In drivers/char/stallion.c: + - find the definition of the stl_brdconf array (of structures) + near the top of the file + - modify this to match the boards you are going to install + (the comments before this structure should help) + - save and exit + +If using ONboard, Brumby, Stallion or EasyConnection 8/64 (ISA or EISA) +boards, + In drivers/char/istallion.c: + - find the definition of the stli_brdconf array (of structures) + near the top of the file + - modify this to match the boards you are going to install + (the comments before this structure should help) + - save and exit + +Once you have set up the board configurations then you are ready to build +the kernel or modules. + +When the new kernel is booted, or the loadable module loaded then the +driver will emit some kernel trace messages about whether the configured +boards were detected or not. Depending on how your system logger is set +up these may come out on the console, or just be logged to +/var/adm/messages or /var/log/syslog. You should check the messages to +confirm that all is well. + + +2.3 SHARING INTERRUPTS + +It is possible to share interrupts between multiple EasyIO and +EasyConnection 8/32 boards in an EISA system. To do this you must be using +static driver configuration, modifying the driver source code to add driver +configuration. Then a couple of extra things are required: + +1. When entering the board resources into the stallion.c file you need to + mark the boards as using level triggered interrupts. Do this by replacing + the "0" entry at field position 6 (the last field) in the board + configuration structure with a "1". (This is the structure that defines + the board type, I/O locations, etc. for each board). All boards that are + sharing an interrupt must be set this way, and each board should have the + same interrupt number specified here as well. Now build the module or + kernel as you would normally. + +2. When physically installing the boards into the system you must enter + the system EISA configuration utility. You will need to install the EISA + configuration files for *all* the EasyIO and EasyConnection 8/32 boards + that are sharing interrupts. The Stallion EasyIO and EasyConnection 8/32 + EISA configuration files required are supplied by Stallion Technologies + on the EASY Utilities floppy diskette (usually supplied in the box with + the board when purchased. If not, you can pick it up from Stallion's FTP + site, ftp.stallion.com). You will need to edit the board resources to + choose level triggered interrupts, and make sure to set each board's + interrupt to the same IRQ number. + +You must complete both the above steps for this to work. When you reboot +or load the driver your EasyIO and EasyConnection 8/32 boards will be +sharing interrupts. + + +2.4 USING HIGH SHARED MEMORY + +The EasyConnection 8/64-EI, ONboard and Stallion boards are capable of +using shared memory addresses above the usual 640K - 1Mb range. The ONboard +ISA and the Stallion boards can be programmed to use memory addresses up to +16Mb (the ISA bus addressing limit), and the EasyConnection 8/64-EI and +ONboard/E can be programmed for memory addresses up to 4Gb (the EISA bus +addressing limit). + +The higher than 1Mb memory addresses are fully supported by this driver. +Just enter the address as you normally would for a lower than 1Mb address +(in the driver's board configuration structure). + + + +2.5 TROUBLE SHOOTING + +If a board is not found by the driver but is actually in the system then the +most likely problem is that the I/O address is wrong. Change the module load +argument for the loadable module form. Or change it in the driver stallion.c +or istallion.c configuration structure and rebuild the kernel or modules, or +change it on the board. + +On EasyIO and EasyConnection 8/32 boards the IRQ is software programmable, so +if there is a conflict you may need to change the IRQ used for a board. There +are no interrupts to worry about for ONboard, Brumby or EasyConnection 8/64 +(ISA, EISA and MCA) boards. The memory region on EasyConnection 8/64 and +ONboard boards is software programmable, but not on the Brumby boards. + + + +3. USING THE DRIVERS + +3.1 INTELLIGENT DRIVER OPERATION + +The intelligent boards also need to have their "firmware" code downloaded +to them. This is done via a user level application supplied in the driver +utility package called "stlload". Compile this program wherever you dropped +the package files, by typing "make". In its simplest form you can then type + + ./stlload -i cdk.sys + +in this directory and that will download board 0 (assuming board 0 is an +EasyConnection 8/64 or EasyConnection/RA board). To download to an +ONboard, Brumby or Stallion do: + + ./stlload -i 2681.sys + +Normally you would want all boards to be downloaded as part of the standard +system startup. To achieve this, add one of the lines above into the +/etc/rc.d/rc.S or /etc/rc.d/rc.serial file. To download each board just add +the "-b " option to the line. You will need to download code for +every board. You should probably move the stlload program into a system +directory, such as /usr/sbin. Also, the default location of the cdk.sys image +file in the stlload down-loader is /usr/lib/stallion. Create that directory +and put the cdk.sys and 2681.sys files in it. (It's a convenient place to put +them anyway). As an example your /etc/rc.d/rc.S file might have the +following lines added to it (if you had 3 boards): + + /usr/sbin/stlload -b 0 -i /usr/lib/stallion/cdk.sys + /usr/sbin/stlload -b 1 -i /usr/lib/stallion/2681.sys + /usr/sbin/stlload -b 2 -i /usr/lib/stallion/2681.sys + +The image files cdk.sys and 2681.sys are specific to the board types. The +cdk.sys will only function correctly on an EasyConnection 8/64 board. Similarly +the 2681.sys image fill only operate on ONboard, Brumby and Stallion boards. +If you load the wrong image file into a board it will fail to start up, and +of course the ports will not be operational! + +If you are using the modularized version of the driver you might want to put +the modprobe calls in the startup script as well (before the download lines +obviously). + + +3.2 USING THE SERIAL PORTS + +Once the driver is installed you will need to setup some device nodes to +access the serial ports. The simplest method is to use the /dev/MAKEDEV program. +It will automatically create device entries for Stallion boards. This will +create the normal serial port devices as /dev/ttyE# where# is the port number +starting from 0. A bank of 64 minor device numbers is allocated to each board, +so the first port on the second board is port 64,etc. A set of callout type +devices may also be created. They are created as the devices /dev/cue# where # +is the same as for the ttyE devices. + +For the most part the Stallion driver tries to emulate the standard PC system +COM ports and the standard Linux serial driver. The idea is that you should +be able to use Stallion board ports and COM ports interchangeably without +modifying anything but the device name. Anything that doesn't work like that +should be considered a bug in this driver! + +If you look at the driver code you will notice that it is fairly closely +based on the Linux serial driver (linux/drivers/char/serial.c). This is +intentional, obviously this is the easiest way to emulate its behavior! + +Since this driver tries to emulate the standard serial ports as much as +possible, most system utilities should work as they do for the standard +COM ports. Most importantly "stty" works as expected and "setserial" can +also be used (excepting the ability to auto-configure the I/O and IRQ +addresses of boards). Higher baud rates are supported in the usual fashion +through setserial or using the CBAUDEX extensions. Note that the EasyIO and +EasyConnection (all types) support at least 57600 and 115200 baud. The newer +EasyConnection XP modules and new EasyIO boards support 230400 and 460800 +baud as well. The older boards including ONboard and Brumby support a +maximum baud rate of 38400. + +If you are unfamiliar with how to use serial ports, then get the Serial-HOWTO +by Greg Hankins. It will explain everything you need to know! + + + +4. NOTES + +You can use both drivers at once if you have a mix of board types installed +in a system. However to do this you will need to change the major numbers +used by one of the drivers. Currently both drivers use major numbers 24, 25 +and 28 for their devices. Change one driver to use some other major numbers, +and then modify the mkdevnods script to make device nodes based on those new +major numbers. For example, you could change the istallion.c driver to use +major numbers 60, 61 and 62. You will also need to create device nodes with +different names for the ports, for example ttyF# and cuf#. + +The original Stallion board is no longer supported by Stallion Technologies. +Although it is known to work with the istallion driver. + +Finding a free physical memory address range can be a problem. The older +boards like the Stallion and ONboard need large areas (64K or even 128K), so +they can be very difficult to get into a system. If you have 16 Mb of RAM +then you have no choice but to put them somewhere in the 640K -> 1Mb range. +ONboards require 64K, so typically 0xd0000 is good, or 0xe0000 on some +systems. If you have an original Stallion board, "V4.0" or Rev.O, then you +need a 64K memory address space, so again 0xd0000 and 0xe0000 are good. +Older Stallion boards are a much bigger problem. They need 128K of address +space and must be on a 128K boundary. If you don't have a VGA card then +0xc0000 might be usable - there is really no other place you can put them +below 1Mb. + +Both the ONboard and old Stallion boards can use higher memory addresses as +well, but you must have less than 16Mb of RAM to be able to use them. Usual +high memory addresses used include 0xec0000 and 0xf00000. + +The Brumby boards only require 16Kb of address space, so you can usually +squeeze them in somewhere. Common addresses are 0xc8000, 0xcc000, or in +the 0xd0000 range. EasyConnection 8/64 boards are even better, they only +require 4Kb of address space, again usually 0xc8000, 0xcc000 or 0xd0000 +are good. + +If you are using an EasyConnection 8/64-EI or ONboard/E then usually the +0xd0000 or 0xe0000 ranges are the best options below 1Mb. If neither of +them can be used then the high memory support to use the really high address +ranges is the best option. Typically the 2Gb range is convenient for them, +and gets them well out of the way. + +The ports of the EasyIO-8M board do not have DCD or DTR signals. So these +ports cannot be used as real modem devices. Generally, when using these +ports you should only use the cueX devices. + +The driver utility package contains a couple of very useful programs. One +is a serial port statistics collection and display program - very handy +for solving serial port problems.

Ever misplace your Linux +kernel sources? And the manual of one of the boards in your computer? + + +Theory of operation +=================== + +An important thing to know is that the driver itself doesn't have the +firmware for the card. This means that you need the separate package +"sx_firmware". For now you can get the source at + + ftp://ftp.bitwizard.nl/specialix/sx_firmware_.tgz + +The firmware load needs a "misc" device, so you'll need to enable the +"Support for user misc device modules" in your kernel configuration. +The misc device needs to be called "/dev/specialix_sxctl". It needs +misc major 10, and minor number 167 (assigned by HPA). The section +on creating device files below also creates this device. + +After loading the sx.o module into your kernel, the driver will report +the number of cards detected, but because it doesn't have any +firmware, it will not be able to determine the number of ports. Only +when you then run "sx_firmware" will the firmware be downloaded and +the rest of the driver initialized. At that time the sx_firmware +program will report the number of ports installed. + +In contrast with many other multi port serial cards, some of the data +structures are only allocated when the card knows the number of ports +that are connected. This means we won't waste memory for 120 port +descriptor structures when you only have 8 ports. If you experience +problems due to this, please report them: I haven't seen any. + + +Interrupts +========== + +A multi port serial card, would generate a horrendous amount of +interrupts if it would interrupt the CPU for every received +character. Even more than 10 years ago, the trick not to use +interrupts but to poll the serial cards was invented. + +The SX card allow us to do this two ways. First the card limits its +own interrupt rate to a rate that won't overwhelm the CPU. Secondly, +we could forget about the cards interrupt completely and use the +internal timer for this purpose. + +Polling the card can take up to a few percent of your CPU. Using the +interrupts would be better if you have most of the ports idle. Using +timer-based polling is better if your card almost always has work to +do. You save the separate interrupt in that case. + +In any case, it doesn't really matter all that much. + +The most common problem with interrupts is that for ISA cards in a PCI +system the BIOS has to be told to configure that interrupt as "legacy +ISA". Otherwise the card can pull on the interrupt line all it wants +but the CPU won't see this. + +If you can't get the interrupt to work, remember that polling mode is +more efficient (provided you actually use the card intensively). + + +Allowed Configurations +====================== + +Some configurations are disallowed. Even though at a glance they might +seem to work, they are known to lockup the bus between the host card +and the device concentrators. You should respect the drivers decision +not to support certain configurations. It's there for a reason. + +Warning: Seriously technical stuff ahead. Executive summary: Don't use +SX cards except configured at a 64k boundary. Skip the next paragraph. + +The SX cards can theoretically be placed at a 32k boundary. So for +instance you can put an SX card at 0xc8000-0xd7fff. This is not a +"recommended configuration". ISA cards have to tell the bus controller +how they like their timing. Due to timing issues they have to do this +based on which 64k window the address falls into. This means that the +32k window below and above the SX card have to use exactly the same +timing as the SX card. That reportedly works for other SX cards. But +you're still left with two useless 32k windows that should not be used +by anybody else. + + +Configuring the driver +====================== + +PCI cards are always detected. The driver auto-probes for ISA cards at +some sensible addresses. Please report if the auto-probe causes trouble +in your system, or when a card isn't detected. + +I'm afraid I haven't implemented "kernel command line parameters" yet. +This means that if the default doesn't work for you, you shouldn't use +the compiled-into-the-kernel version of the driver. Use a module +instead. If you convince me that you need this, I'll make it for +you. Deal? + +I'm afraid that the module parameters are a bit clumsy. If you have a +better idea, please tell me. + +You can specify several parameters: + + sx_poll: number of jiffies between timer-based polls. + + Set this to "0" to disable timer based polls. + Initialization of cards without a working interrupt + will fail. + + Set this to "1" if you want a polling driver. + (on Intel: 100 polls per second). If you don't use + fast baud rates, you might consider a value like "5". + (If you don't know how to do the math, use 1). + + sx_slowpoll: Number of jiffies between timer-based polls. + Set this to "100" to poll once a second. + This should get the card out of a stall if the driver + ever misses an interrupt. I've never seen this happen, + and if it does, that's a bug. Tell me. + + sx_maxints: Number of interrupts to request from the card. + The card normally limits interrupts to about 100 per + second to offload the host CPU. You can increase this + number to reduce latency on the card a little. + Note that if you give a very high number you can overload + your CPU as well as the CPU on the host card. This setting + is inaccurate and not recommended for SI cards (But it + works). + + sx_irqmask: The mask of allowable IRQs to use. I suggest you set + this to 0 (disable IRQs all together) and use polling if + the assignment of IRQs becomes problematic. This is defined + as the sum of (1 << irq) 's that you want to allow. So + sx_irqmask of 8 (1 << 3) specifies that only irq 3 may + be used by the SX driver. If you want to specify to the + driver: "Either irq 11 or 12 is ok for you to use", then + specify (1 << 11) | (1 << 12) = 0x1800 . + + sx_debug: You can enable different sorts of debug traces with this. + At "-1" all debugging traces are active. You'll get several + times more debugging output than you'll get characters + transmitted. + + +Baud rates +========== + +Theoretically new SXDCs should be capable of more than 460k +baud. However the line drivers usually give up before that. Also the +CPU on the card may not be able to handle 8 channels going at full +blast at that speed. Moreover, the buffers are not large enough to +allow operation with 100 interrupts per second. You'll have to realize +that the card has a 256 byte buffer, so you'll have to increase the +number of interrupts per second if you have more than 256*100 bytes +per second to transmit. If you do any performance testing in this +area, I'd be glad to hear from you... + +(Psst Linux users..... I think the Linux driver is more efficient than +the driver for other OSes. If you can and want to benchmark them +against each other, be my guest, and report your findings...... :-) + + +Ports and devices +================= + +Port 0 is the top connector on the module closest to the host +card. Oh, the ports on the SXDCs and TAs are labelled from 1 to 8 +instead of from 0 to 7, as they are numbered by linux. I'm stubborn in +this: I know for sure that I wouldn't be able to calculate which port +is which anymore if I would change that.... + + +Devices: + +You should make the device files as follows: + +#!/bin/sh +# (I recommend that you cut-and-paste this into a file and run that) +cd /dev +t=0 +mknod specialix_sxctl c 10 167 +while [ $t -lt 64 ] + do + echo -n "$t " + mknod ttyX$t c 32 $t + mknod cux$t c 33 $t + t=`expr $t + 1` +done +echo "" +rm /etc/psdevtab +ps > /dev/null + + +This creates 64 devices. If you have more, increase the constant on +the line with "while". The devices start at 0, as is customary on +Linux. Specialix seems to like starting the numbering at 1. + +If your system doesn't come with these devices pre-installed, bug your +linux-vendor about this. They should have these devices +"pre-installed" before the new millennium. The "ps" stuff at the end +is to "tell" ps that the new devices exist. + +Officially the maximum number of cards per computer is 4. This driver +however supports as many cards in one machine as you want. You'll run +out of interrupts after a few, but you can switch to polled operation +then. At about 256 ports (More than 8 cards), we run out of minor +device numbers. Sorry. I suggest you buy a second computer....

This would become - - append="specialix=0x100,9,0x250,11,0x180,15" - -in your /etc/lilo.conf file if you use lilo. - -The Specialix driver is slightly odd: It allows you to have the second -or third card detected without having a first card. This has -advantages and disadvantages. A slot that isn't filled by an ISA card, -might be filled if a PCI card is detected. Thus if you have an ISA -card at 0x250 and a PCI card, you would get: - -sx0: specialix IO8+ Board at 0x100 not found. -sx1: specialix IO8+ Board at 0x180 not found. -sx2: specialix IO8+ board detected at 0x250, IRQ 12, CD1865 Rev. B. -sx3: specialix IO8+ Board at 0x260 not found. -sx0: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B. - -This would happen if you don't give any probe hints to the driver. -If you would specify: - - specialix=0x250,11 - -you'd get the following messages: - -sx0: specialix IO8+ board detected at 0x250, IRQ 11, CD1865 Rev. B. -sx1: specialix IO8+ board detected at 0xd800, IRQ 9, CD1865 Rev. B. - -ISA probing is aborted after the IO address you gave is exhausted, and -the PCI card is now detected as the second card. The ISA card is now -also forced to IRQ11.... - - -Baud rates -========== - -The rev 1.2 and below boards use a CL-CD1864. These chips can only -do 64kbit. The rev 1.3 and newer boards use a CL-CD1865. These chips -are officially capable of 115k2. - -The Specialix card uses a 25MHz crystal (in times two mode, which in -fact is a divided by two mode). This is not enough to reach the rated -115k2 on all ports at the same time. With this clock rate you can only -do 37% of this rate. This means that at 115k2 on all ports you are -going to lose characters (The chip cannot handle that many incoming -bits at this clock rate.) (Yes, you read that correctly: there is a -limit to the number of -=bits=- per second that the chip can handle.) - -If you near the "limit" you will first start to see a graceful -degradation in that the chip cannot keep the transmitter busy at all -times. However with a central clock this slow, you can also get it to -miss incoming characters. The driver will print a warning message when -you are outside the official specs. The messages usually show up in -the file /var/log/messages . - -The specialix card cannot reliably do 115k2. If you use it, you have -to do "extensive testing" (*) to verify if it actually works. - -When "mgetty" communicates with my modem at 115k2 it reports: -got: +++[0d]ATQ0V1H0[0d][0d][8a]O[cb][0d][8a] - ^^^^ ^^^^ ^^^^ - -The three characters that have the "^^^" under them have suffered a -bit error in the highest bit.

If -it doesn't fit in your computer, bring back the card. - - ------------------------------------------------------------------------- - - - Fixed bugs and restrictions: - - During initialization, interrupts are blindly turned on. - Having a shadow variable would cause an extra memory - access on every IO instruction. - - The interrupt (on the card) should be disabled when we - don't allocate the Linux end of the interrupt. This allows - a different driver/card to use it while all ports are not in - use..... (a la standard serial port) - == An extra _off variant of the sx_in and sx_out macros are - now available. They don't set the interrupt enable bit. - These are used during initialization.

Neat! - - Can you set the IO address from the lilo command line? - If you need this, bug me about it, I'll make it. - == Hah! No bugging needed. Fixed! :-) - - Cirrus logic hasn't gotten back to me yet why the CD1865 can - and the CD1864 can't do 115k2. I suspect that this is - because the CD1864 is not rated for 33MHz operation. - Therefore the CD1864 versions of the card can't do 115k2 on - all ports just like the CD1865 versions. The driver does - not block 115k2 on CD1864 cards. - == I called the Cirrus Logic representative here in Holland. - The CD1864 databook is identical to the CD1865 databook, - except for an extra warning at the end. Similar Bit errors - have been observed in testing at 115k2 on both an 1865 and - a 1864 chip. I see no reason why I would prohibit 115k2 on - 1864 chips and not do it on 1865 chips. Actually there is - reason to prohibit it on BOTH chips. I print a warning. - If you use 115k2, you're on your own. - - A spiky CD may send spurious HUPs.

INTRODUCTION - -There are two drivers that work with the different families of Stallion -multiport serial boards. One is for the Stallion smart boards - that is -EasyIO, EasyConnection 8/32 and EasyConnection 8/64-PCI, the other for -the true Stallion intelligent multiport boards - EasyConnection 8/64 -(ISA, EISA, MCA), EasyConnection/RA-PCI, ONboard and Brumby. - -If you are using any of the Stallion intelligent multiport boards (Brumby, -ONboard, EasyConnection 8/64 (ISA, EISA, MCA), EasyConnection/RA-PCI) with -Linux you will need to get the driver utility package. This contains a -firmware loader and the firmware images necessary to make the devices operate. - -The Stallion Technologies ftp site, ftp.stallion.com, will always have -the latest version of the driver utility package. - -ftp://ftp.stallion.com/drivers/ata5/Linux/ata-linux-550.tar.gz - -As of the printing of this document the latest version of the driver -utility package is 5.5.0. If a later version is now available then you -should use the latest version. - -If you are using the EasyIO, EasyConnection 8/32 or EasyConnection 8/64-PCI -boards then you don't need this package, although it does have a serial stats -display program. - -If you require DIP switch settings, EISA or MCA configuration files, or any -other information related to Stallion boards then have a look at Stallion's -web pages at http://www.stallion.com. - - - -2. INSTALLATION - -The drivers can be used as loadable modules or compiled into the kernel. -You can choose which when doing a "config" on the kernel. - -All ISA, EISA and MCA boards that you want to use need to be configured into -the driver(s). All PCI boards will be automatically detected when you load -the driver - so they do not need to be entered into the driver(s) -configuration structure. Note that kernel PCI support is required to use PCI -boards. - -There are two methods of configuring ISA, EISA and MCA boards into the drivers. -If using the driver as a loadable module then the simplest method is to pass -the driver configuration as module arguments. The other method is to modify -the driver source to add configuration lines for each board in use. - -If you have pre-built Stallion driver modules then the module argument -configuration method should be used. A lot of Linux distributions come with -pre-built driver modules in /lib/modules/X.Y.Z/misc for the kernel in use. -That makes things pretty simple to get going. - - -2.1 MODULE DRIVER CONFIGURATION: - -The simplest configuration for modules is to use the module load arguments -to configure any ISA, EISA or MCA boards. PCI boards are automatically -detected, so do not need any additional configuration at all. - -If using EasyIO, EasyConnection 8/32 ISA or MCA, or EasyConnection 8/63-PCI -boards then use the "stallion" driver module, Otherwise if you are using -an EasyConnection 8/64 ISA, EISA or MCA, EasyConnection/RA-PCI, ONboard, -Brumby or original Stallion board then use the "istallion" driver module. - -Typically to load up the smart board driver use: - - modprobe stallion - -This will load the EasyIO and EasyConnection 8/32 driver. It will output a -message to say that it loaded and print the driver version number. It will -also print out whether it found the configured boards or not. These messages -may not appear on the console, but typically are always logged to -/var/adm/messages or /var/log/syslog files - depending on how the klogd and -syslogd daemons are setup on your system. - -To load the intelligent board driver use: - - modprobe istallion - -It will output similar messages to the smart board driver. - -If not using an auto-detectable board type (that is a PCI board) then you -will also need to supply command line arguments to the modprobe command -when loading the driver. The general form of the configuration argument is - - board?=[,[,][,]] - -where: - - board? -- specifies the arbitrary board number of this board, - can be in the range 0 to 3. - - name -- textual name of this board. The board name is the common - board name, or any "shortened" version of that. The board - type number may also be used here. - - ioaddr -- specifies the I/O address of this board. This argument is - optional, but should generally be specified. - - addr -- optional second address argument. Some board types require - a second I/O address, some require a memory address. The - exact meaning of this argument depends on the board type. - - irq -- optional IRQ line used by this board. - -Up to 4 board configuration arguments can be specified on the load line. -Here is some examples: - - modprobe stallion board0=easyio,0x2a0,5 - -This configures an EasyIO board as board 0 at I/O address 0x2a0 and IRQ 5. - - modprobe istallion board3=ec8/64,0x2c0,0xcc000 - -This configures an EasyConnection 8/64 ISA as board 3 at I/O address 0x2c0 at -memory address 0xcc000. - - modprobe stallion board1=ec8/32-at,0x2a0,0x280,10 - -This configures an EasyConnection 8/32 ISA board at primary I/O address 0x2a0, -secondary address 0x280 and IRQ 10. - -You will probably want to enter this module load and configuration information -into your system startup scripts so that the drivers are loaded and configured -on each system boot. Typically the start up script would be something like -/etc/modprobe.conf. - - -2.2 STATIC DRIVER CONFIGURATION: - -For static driver configuration you need to modify the driver source code. -Entering ISA, EISA and MCA boards into the driver(s) configuration structure -involves editing the driver(s) source file. It's pretty easy if you follow -the instructions below. Both drivers can support up to 4 boards. The smart -card driver (the stallion.c driver) supports any combination of EasyIO and -EasyConnection 8/32 boards (up to a total of 4). The intelligent driver -supports any combination of ONboards, Brumbys, Stallions and EasyConnection -8/64 (ISA and EISA) boards (up to a total of 4). - -To set up the driver(s) for the boards that you want to use you need to -edit the appropriate driver file and add configuration entries. - -If using EasyIO or EasyConnection 8/32 ISA or MCA boards, - In drivers/char/stallion.c: - - find the definition of the stl_brdconf array (of structures) - near the top of the file - - modify this to match the boards you are going to install - (the comments before this structure should help) - - save and exit - -If using ONboard, Brumby, Stallion or EasyConnection 8/64 (ISA or EISA) -boards, - In drivers/char/istallion.c: - - find the definition of the stli_brdconf array (of structures) - near the top of the file - - modify this to match the boards you are going to install - (the comments before this structure should help) - - save and exit - -Once you have set up the board configurations then you are ready to build -the kernel or modules. - -When the new kernel is booted, or the loadable module loaded then the -driver will emit some kernel trace messages about whether the configured -boards were detected or not. Depending on how your system logger is set -up these may come out on the console, or just be logged to -/var/adm/messages or /var/log/syslog. You should check the messages to -confirm that all is well. - - -2.3 SHARING INTERRUPTS - -It is possible to share interrupts between multiple EasyIO and -EasyConnection 8/32 boards in an EISA system. To do this you must be using -static driver configuration, modifying the driver source code to add driver -configuration. Then a couple of extra things are required: - -1. When entering the board resources into the stallion.c file you need to - mark the boards as using level triggered interrupts. Do this by replacing - the "0" entry at field position 6 (the last field) in the board - configuration structure with a "1". (This is the structure that defines - the board type, I/O locations, etc. for each board). All boards that are - sharing an interrupt must be set this way, and each board should have the - same interrupt number specified here as well. Now build the module or - kernel as you would normally. - -2. When physically installing the boards into the system you must enter - the system EISA configuration utility. You will need to install the EISA - configuration files for *all* the EasyIO and EasyConnection 8/32 boards - that are sharing interrupts. The Stallion EasyIO and EasyConnection 8/32 - EISA configuration files required are supplied by Stallion Technologies - on the EASY Utilities floppy diskette (usually supplied in the box with - the board when purchased. If not, you can pick it up from Stallion's FTP - site, ftp.stallion.com). You will need to edit the board resources to - choose level triggered interrupts, and make sure to set each board's - interrupt to the same IRQ number. - -You must complete both the above steps for this to work. When you reboot -or load the driver your EasyIO and EasyConnection 8/32 boards will be -sharing interrupts. - - -2.4 USING HIGH SHARED MEMORY - -The EasyConnection 8/64-EI, ONboard and Stallion boards are capable of -using shared memory addresses above the usual 640K - 1Mb range. The ONboard -ISA and the Stallion boards can be programmed to use memory addresses up to -16Mb (the ISA bus addressing limit), and the EasyConnection 8/64-EI and -ONboard/E can be programmed for memory addresses up to 4Gb (the EISA bus -addressing limit). - -The higher than 1Mb memory addresses are fully supported by this driver. -Just enter the address as you normally would for a lower than 1Mb address -(in the driver's board configuration structure). - - - -2.5 TROUBLE SHOOTING - -If a board is not found by the driver but is actually in the system then the -most likely problem is that the I/O address is wrong. Change the module load -argument for the loadable module form. Or change it in the driver stallion.c -or istallion.c configuration structure and rebuild the kernel or modules, or -change it on the board. - -On EasyIO and EasyConnection 8/32 boards the IRQ is software programmable, so -if there is a conflict you may need to change the IRQ used for a board. There -are no interrupts to worry about for ONboard, Brumby or EasyConnection 8/64 -(ISA, EISA and MCA) boards. The memory region on EasyConnection 8/64 and -ONboard boards is software programmable, but not on the Brumby boards. - - - -3. USING THE DRIVERS - -3.1 INTELLIGENT DRIVER OPERATION - -The intelligent boards also need to have their "firmware" code downloaded -to them. This is done via a user level application supplied in the driver -utility package called "stlload". Compile this program wherever you dropped -the package files, by typing "make". In its simplest form you can then type - - ./stlload -i cdk.sys - -in this directory and that will download board 0 (assuming board 0 is an -EasyConnection 8/64 or EasyConnection/RA board). To download to an -ONboard, Brumby or Stallion do: - - ./stlload -i 2681.sys - -Normally you would want all boards to be downloaded as part of the standard -system startup. To achieve this, add one of the lines above into the -/etc/rc.d/rc.S or /etc/rc.d/rc.serial file. To download each board just add -the "-b " option to the line. You will need to download code for -every board. You should probably move the stlload program into a system -directory, such as /usr/sbin. Also, the default location of the cdk.sys image -file in the stlload down-loader is /usr/lib/stallion. Create that directory -and put the cdk.sys and 2681.sys files in it. (It's a convenient place to put -them anyway). As an example your /etc/rc.d/rc.S file might have the -following lines added to it (if you had 3 boards): - - /usr/sbin/stlload -b 0 -i /usr/lib/stallion/cdk.sys - /usr/sbin/stlload -b 1 -i /usr/lib/stallion/2681.sys - /usr/sbin/stlload -b 2 -i /usr/lib/stallion/2681.sys - -The image files cdk.sys and 2681.sys are specific to the board types. The -cdk.sys will only function correctly on an EasyConnection 8/64 board. Similarly -the 2681.sys image fill only operate on ONboard, Brumby and Stallion boards. -If you load the wrong image file into a board it will fail to start up, and -of course the ports will not be operational! - -If you are using the modularized version of the driver you might want to put -the modprobe calls in the startup script as well (before the download lines -obviously). - - -3.2 USING THE SERIAL PORTS - -Once the driver is installed you will need to setup some device nodes to -access the serial ports. The simplest method is to use the /dev/MAKEDEV program. -It will automatically create device entries for Stallion boards. This will -create the normal serial port devices as /dev/ttyE# where# is the port number -starting from 0. A bank of 64 minor device numbers is allocated to each board, -so the first port on the second board is port 64,etc. A set of callout type -devices may also be created. They are created as the devices /dev/cue# where # -is the same as for the ttyE devices. - -For the most part the Stallion driver tries to emulate the standard PC system -COM ports and the standard Linux serial driver. The idea is that you should -be able to use Stallion board ports and COM ports interchangeably without -modifying anything but the device name. Anything that doesn't work like that -should be considered a bug in this driver! - -If you look at the driver code you will notice that it is fairly closely -based on the Linux serial driver (linux/drivers/char/serial.c). This is -intentional, obviously this is the easiest way to emulate its behavior! - -Since this driver tries to emulate the standard serial ports as much as -possible, most system utilities should work as they do for the standard -COM ports. Most importantly "stty" works as expected and "setserial" can -also be used (excepting the ability to auto-configure the I/O and IRQ -addresses of boards). Higher baud rates are supported in the usual fashion -through setserial or using the CBAUDEX extensions. Note that the EasyIO and -EasyConnection (all types) support at least 57600 and 115200 baud. The newer -EasyConnection XP modules and new EasyIO boards support 230400 and 460800 -baud as well. The older boards including ONboard and Brumby support a -maximum baud rate of 38400. - -If you are unfamiliar with how to use serial ports, then get the Serial-HOWTO -by Greg Hankins. It will explain everything you need to know! - - - -4. NOTES - -You can use both drivers at once if you have a mix of board types installed -in a system. However to do this you will need to change the major numbers -used by one of the drivers. Currently both drivers use major numbers 24, 25 -and 28 for their devices. Change one driver to use some other major numbers, -and then modify the mkdevnods script to make device nodes based on those new -major numbers. For example, you could change the istallion.c driver to use -major numbers 60, 61 and 62. You will also need to create device nodes with -different names for the ports, for example ttyF# and cuf#. - -The original Stallion board is no longer supported by Stallion Technologies. -Although it is known to work with the istallion driver. - -Finding a free physical memory address range can be a problem. The older -boards like the Stallion and ONboard need large areas (64K or even 128K), so -they can be very difficult to get into a system. If you have 16 Mb of RAM -then you have no choice but to put them somewhere in the 640K -> 1Mb range. -ONboards require 64K, so typically 0xd0000 is good, or 0xe0000 on some -systems. If you have an original Stallion board, "V4.0" or Rev.O, then you -need a 64K memory address space, so again 0xd0000 and 0xe0000 are good. -Older Stallion boards are a much bigger problem. They need 128K of address -space and must be on a 128K boundary. If you don't have a VGA card then -0xc0000 might be usable - there is really no other place you can put them -below 1Mb. - -Both the ONboard and old Stallion boards can use higher memory addresses as -well, but you must have less than 16Mb of RAM to be able to use them. Usual -high memory addresses used include 0xec0000 and 0xf00000. - -The Brumby boards only require 16Kb of address space, so you can usually -squeeze them in somewhere. Common addresses are 0xc8000, 0xcc000, or in -the 0xd0000 range. EasyConnection 8/64 boards are even better, they only -require 4Kb of address space, again usually 0xc8000, 0xcc000 or 0xd0000 -are good. - -If you are using an EasyConnection 8/64-EI or ONboard/E then usually the -0xd0000 or 0xe0000 ranges are the best options below 1Mb. If neither of -them can be used then the high memory support to use the really high address -ranges is the best option. Typically the 2Gb range is convenient for them, -and gets them well out of the way. - -The ports of the EasyIO-8M board do not have DCD or DTR signals. So these -ports cannot be used as real modem devices. Generally, when using these -ports you should only use the cueX devices. - -The driver utility package contains a couple of very useful programs. One -is a serial port statistics collection and display program - very handy -for solving serial port problems.

Ever misplace your Linux -kernel sources? And the manual of one of the boards in your computer? - - -Theory of operation -=================== - -An important thing to know is that the driver itself doesn't have the -firmware for the card. This means that you need the separate package -"sx_firmware". For now you can get the source at - - ftp://ftp.bitwizard.nl/specialix/sx_firmware_.tgz - -The firmware load needs a "misc" device, so you'll need to enable the -"Support for user misc device modules" in your kernel configuration. -The misc device needs to be called "/dev/specialix_sxctl". It needs -misc major 10, and minor number 167 (assigned by HPA). The section -on creating device files below also creates this device. - -After loading the sx.o module into your kernel, the driver will report -the number of cards detected, but because it doesn't have any -firmware, it will not be able to determine the number of ports. Only -when you then run "sx_firmware" will the firmware be downloaded and -the rest of the driver initialized. At that time the sx_firmware -program will report the number of ports installed. - -In contrast with many other multi port serial cards, some of the data -structures are only allocated when the card knows the number of ports -that are connected. This means we won't waste memory for 120 port -descriptor structures when you only have 8 ports. If you experience -problems due to this, please report them: I haven't seen any. - - -Interrupts -========== - -A multi port serial card, would generate a horrendous amount of -interrupts if it would interrupt the CPU for every received -character. Even more than 10 years ago, the trick not to use -interrupts but to poll the serial cards was invented. - -The SX card allow us to do this two ways. First the card limits its -own interrupt rate to a rate that won't overwhelm the CPU. Secondly, -we could forget about the cards interrupt completely and use the -internal timer for this purpose. - -Polling the card can take up to a few percent of your CPU. Using the -interrupts would be better if you have most of the ports idle. Using -timer-based polling is better if your card almost always has work to -do. You save the separate interrupt in that case. - -In any case, it doesn't really matter all that much. - -The most common problem with interrupts is that for ISA cards in a PCI -system the BIOS has to be told to configure that interrupt as "legacy -ISA". Otherwise the card can pull on the interrupt line all it wants -but the CPU won't see this. - -If you can't get the interrupt to work, remember that polling mode is -more efficient (provided you actually use the card intensively). - - -Allowed Configurations -====================== - -Some configurations are disallowed. Even though at a glance they might -seem to work, they are known to lockup the bus between the host card -and the device concentrators. You should respect the drivers decision -not to support certain configurations. It's there for a reason. - -Warning: Seriously technical stuff ahead. Executive summary: Don't use -SX cards except configured at a 64k boundary. Skip the next paragraph. - -The SX cards can theoretically be placed at a 32k boundary. So for -instance you can put an SX card at 0xc8000-0xd7fff. This is not a -"recommended configuration". ISA cards have to tell the bus controller -how they like their timing. Due to timing issues they have to do this -based on which 64k window the address falls into. This means that the -32k window below and above the SX card have to use exactly the same -timing as the SX card. That reportedly works for other SX cards. But -you're still left with two useless 32k windows that should not be used -by anybody else. - - -Configuring the driver -====================== - -PCI cards are always detected. The driver auto-probes for ISA cards at -some sensible addresses. Please report if the auto-probe causes trouble -in your system, or when a card isn't detected. - -I'm afraid I haven't implemented "kernel command line parameters" yet. -This means that if the default doesn't work for you, you shouldn't use -the compiled-into-the-kernel version of the driver. Use a module -instead. If you convince me that you need this, I'll make it for -you. Deal? - -I'm afraid that the module parameters are a bit clumsy. If you have a -better idea, please tell me. - -You can specify several parameters: - - sx_poll: number of jiffies between timer-based polls. - - Set this to "0" to disable timer based polls. - Initialization of cards without a working interrupt - will fail. - - Set this to "1" if you want a polling driver. - (on Intel: 100 polls per second). If you don't use - fast baud rates, you might consider a value like "5". - (If you don't know how to do the math, use 1). - - sx_slowpoll: Number of jiffies between timer-based polls. - Set this to "100" to poll once a second. - This should get the card out of a stall if the driver - ever misses an interrupt. I've never seen this happen, - and if it does, that's a bug. Tell me. - - sx_maxints: Number of interrupts to request from the card. - The card normally limits interrupts to about 100 per - second to offload the host CPU. You can increase this - number to reduce latency on the card a little. - Note that if you give a very high number you can overload - your CPU as well as the CPU on the host card. This setting - is inaccurate and not recommended for SI cards (But it - works). - - sx_irqmask: The mask of allowable IRQs to use. I suggest you set - this to 0 (disable IRQs all together) and use polling if - the assignment of IRQs becomes problematic. This is defined - as the sum of (1 << irq) 's that you want to allow. So - sx_irqmask of 8 (1 << 3) specifies that only irq 3 may - be used by the SX driver. If you want to specify to the - driver: "Either irq 11 or 12 is ok for you to use", then - specify (1 << 11) | (1 << 12) = 0x1800 . - - sx_debug: You can enable different sorts of debug traces with this. - At "-1" all debugging traces are active. You'll get several - times more debugging output than you'll get characters - transmitted. - - -Baud rates -========== - -Theoretically new SXDCs should be capable of more than 460k -baud. However the line drivers usually give up before that. Also the -CPU on the card may not be able to handle 8 channels going at full -blast at that speed. Moreover, the buffers are not large enough to -allow operation with 100 interrupts per second. You'll have to realize -that the card has a 256 byte buffer, so you'll have to increase the -number of interrupts per second if you have more than 256*100 bytes -per second to transmit. If you do any performance testing in this -area, I'd be glad to hear from you... - -(Psst Linux users..... I think the Linux driver is more efficient than -the driver for other OSes. If you can and want to benchmark them -against each other, be my guest, and report your findings...... :-) - - -Ports and devices -================= - -Port 0 is the top connector on the module closest to the host -card. Oh, the ports on the SXDCs and TAs are labelled from 1 to 8 -instead of from 0 to 7, as they are numbered by linux. I'm stubborn in -this: I know for sure that I wouldn't be able to calculate which port -is which anymore if I would change that.... - - -Devices: - -You should make the device files as follows: - -#!/bin/sh -# (I recommend that you cut-and-paste this into a file and run that) -cd /dev -t=0 -mknod specialix_sxctl c 10 167 -while [ $t -lt 64 ] - do - echo -n "$t " - mknod ttyX$t c 32 $t - mknod cux$t c 33 $t - t=`expr $t + 1` -done -echo "" -rm /etc/psdevtab -ps > /dev/null - - -This creates 64 devices. If you have more, increase the constant on -the line with "while". The devices start at 0, as is customary on -Linux. Specialix seems to like starting the numbering at 1. - -If your system doesn't come with these devices pre-installed, bug your -linux-vendor about this. They should have these devices -"pre-installed" before the new millennium. The "ps" stuff at the end -is to "tell" ps that the new devices exist. - -Officially the maximum number of cards per computer is 4. This driver -however supports as many cards in one machine as you want. You'll run -out of interrupts after a few, but you can switch to polled operation -then. At about 256 ports (More than 8 cards), we run out of minor -device numbers. Sorry. I suggest you buy a second computer....

In function scm_fp_dup(), the INIT_LIST_HEAD(&fpl->list) of newly created fpl is done *before* the subsequent memcpy from the old structure and thus the freshly initialized list is overwritten. But that's OK, since this initialization is not required at all, since the fpl->list is list_add-ed at the destruction time in any case (and is unused in other code), so I propose to drop both initializations, rather than moving it after the memcpy.

The right function to use in this situation is device_del(), which unregisters the device from the system like device_unregister() does, but without dropping the reference count an additional time.

Disable the sharing of SMB and tcon structs for now until we can come up with a way to do this that's race free. We want to continue to share TCP sessions, however since they are required for multiuser mounts. For that, implement a new (hopefully race-free) scheme. Add a new global list of TCP sessions, and take care to get a reference to it whenever we're dealing with one.

PHY status if available. 2. TF register R/W test (only promotes presence, never demotes) 3. device signature after reset 4. IDENTIFY failure detection in SFF state machine Combination of the above works well in most cases but recently there have been a few reports where a phantom device causes unnecessary delay during probe. In both cases, PHY status wasn't available. In one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which didn't qualify as #4. The other failed #2 but as it passed #3 and #4, it still caused failure. In both cases, phantom device reported diagnostic failure, so these cases can be safely worked around by considering any !ATA_DRQ IDENTIFY failure as NODEV_HINT if diagnostic failure is set.

This entails adding a new list head to the TCP_Server_Info struct. The refcounting for the cifsSesInfo is moved to a non-atomic variable. We have to protect it by a lock anyway, so there's no benefit to making it an atomic. The list and refcount are protected by the global cifs_tcp_ses_lock. The patch also adds a new routines to find and put SMB sessions and that properly take and put references under the lock.

A common reason for device drivers to implement their own printk macros is the lack of a printk prefix with the standard pr_xyz macros. Introduce a pr_fmt() macro that is applied for every pr_xyz macro to the format string. The most common use of the pr_fmt macro would be to add the name of the device driver to all pr_xyz messages in a source file.

To kick the watch out we need (in this order) inode->inotify_mutex and ih->mutex. That's fine if we have a hold on inode; however, for all other cases we need to make damn sure we don't race with umount. We can *NOT* just grab a reference to a watch - inotify_unmount_inodes() will happily sail past it and we'll end with reference to inode potentially outliving its superblock. Ideally we just want to grab an active reference to superblock if we can; that will make sure we won't go into inotify_umount_inodes() until we are done. Cleanup is just deactivate_super(). However, that leaves a messy case - what if we *are* racing with umount() and active references to superblock can't be acquired anymore? We can bump ->s_count, grab ->s_umount, which will almost certainly wait until the superblock is shut down and the watch in question is pining for fjords. That's fine, but there is a problem - we might have hit the window between ->s_active getting to 0 / ->s_count - below S_BIAS (i.e. the moment when superblock is past the point of no return and is heading for shutdown) and the moment when deactivate_super() acquires ->s_umount. We could just do drop_super() yield() and retry, but that's rather antisocial and this stuff is luser-triggerable. OTOH, having grabbed ->s_umount and having found that we'd got there first (i.e. that ->s_root is non-NULL) we know that we won't race with inotify_umount_inodes(). So we could grab a reference to watch and do the rest as above, just with drop_super() instead of deactivate_super(), right? Wrong. We had to drop ih->mutex before we could grab ->s_umount. So the watch could've been gone already. That still can be dealt with - we need to save watch->wd, do idr_find() and compare its result with our pointer. If they match, we either have the damn thing still alive or we'd lost not one but two races at once, the watch had been killed and a new one got created with the same ->wd at the same address. That couldn't have happened in inotify_destroy(), but inotify_rm_wd() could run into that. Still, "new one got created" is not a problem - we have every right to kill it or leave it alone, whatever's more convenient. So we can use idr_find(...) == watch && watch->inode->i_sb == sb as "grab it and kill it" check. If it's been our original watch, we are fine, if it's a newcomer - nevermind, just pretend that we'd won the race and kill the fscker anyway; we are safe since we know that its superblock won't be going away. And yes, this is far beyond mere "not very pretty"; so's the entire concept of inotify to start with.

So we can't see this function printing. So, every time the last function to fill the read buffer, if overflowed, will be dropped. This also applies to set_ftrace_filter if set_ftrace_filter has more bytes than read buffer. fix: Through checking return value of seq_printf, if less than 0, we know this function doesn't be printed. Then we decrease position to force this function to be printed next time, in next read buffer. Another little fix is to show correct allocating pages count.

But currently, swiotlb uses dev->dma_mask in alloc_coherent() implicitly via address_needs_mapping(), but alloc_coherent is really supposed to use coherent_dma_mask. This bug could break drivers that uses smaller coherent_dma_mask than dma_mask (though the current code works for the majority that use the same mask for coherent_dma_mask and dma_mask).

With the patch, I see: checking TSC synchronization [CPU#0 -> CPU#1]: Measured 28 cycles TSC warp between CPUs, turning off TSC clock. Marking TSC unstable due to check_tsc_sync_source failed Whereas, without the patch syncs pass fine on all CPUs: checking TSC synchronization [CPU#0 -> CPU#1]: passed. Due to this, TSC is marked unstable, when it is not actually unstable. This is because syncs in check_tsc_wrap() goes away due to this commit. As per the discussion on this thread, correct way to fix this is to add explicit syncs as below?

In order to write contiguous pages whenever possible, cifs_writepages() asks pagevec_lookup_tag() for more pages than it may write at one time. Normally, it then resets index just past the last page written before calling pagevec_lookup_tag() again. If cifs_writepages() can't write the first page returned, it wasn't resetting index, and the next call to pagevec_lookup_tag() resulted in skipping all of the pages it previously returned, even though cifs_writepages() did nothing with them. This can result in data loss when the file descriptor is about to be closed. This patch ensures that index gets set back to the next returned page so that none get skipped.

This patch makes profile_nop function inline and fixes the following warning: WARNING: vmlinux.o(.text+0x6ebb6): Section mismatch in reference from the function create_hash_tables() to the function .init.text:profile_nop() The function create_hash_tables() references the function __init profile_nop(). This is often because create_hash_tables lacks a __init annotation or the annotation of profile_nop is wrong.

We found it on a couple of machines, including T61 notebook, nehalem machine, and another HPC NX6325 notebook. All the machines use FedoraCore 8 or FedoraCore 9. With kernel prior to 2.6.28-rc, system boot doesn't fail. I debug it and locate the root cause. Pls. see http://bugzilla.kernel.org/show_bug.cgi?id=11899 https://bugzilla.redhat.com/show_bug.cgi?id=471517 As a matter of fact, there are 2 bugs. 1)root=/dev/sda1, system boot randomly fails. Mostly, boot for 5 times and fails once. nash has a bug. Some of its functions misuse return value 0. Sometimes, 0 means timeout and no uevent available. Sometimes, 0 means nash gets an uevent, but the uevent isn't block-related (for exmaple, usb). If by coincidence, kernel tells nash that uevents are available, but kernel also set timeout, nash might stops collecting other uevents in queue if current uevent isn't block-related. I work out a patch for nash to fix it. http://bugzilla.kernel.org/attachment.cgi?id=18858 2) root=LABEL=/, system always can't boot. initrd init reports switchroot fails. Here is an executation branch of nash when booting: (1) nash read /sys/block/sda/dev; Assume major is 8 (on my desktop) (2) nash query /proc/devices with the major number; It found line "8 sd"; (3) nash use 'sd' to search its own probe table to find device (DISK) type for the device and add it to its own list; (4) Later on, it probes all devices in its list to get filesystem labels; scsi register "8 sd" always. When major is 259, nash fails to find the device(DISK) type. I enables CONFIG_DEBUG_BLOCK_EXT_DEVT=y when compiling kernel, so 259 is picked up for device /dev/sda1, which causes nash to fail to find device (DISK) type. To fixing issue 2), I create a patch for nash and another patch for kernel. http://bugzilla.kernel.org/attachment.cgi?id=18859 http://bugzilla.kernel.org/attachment.cgi?id=18837 Below is the patch for kernel 2.6.28-rc4. It registers blkext, a new block device in proc/devices. With 2 patches on nash and 1 patch on kernel, I boot my machines for dozens of times without failure.

Since then, it has also been used by iwlwifi to (slightly) speed up re-association after resume, a workaround around the fact that mac80211 has no suspend/resume handling yet. It is also not used by any other drivers, so clearly it cannot be necessary for "good enough" suspend/resume. Unfortunately, the callback suffers from a severe problem: It only works for station mode. If suspend/resume happens while in IBSS or any other mode (but station), then the callback is pointless. Recently, it has created a number of locking issues, first because it required rtnl locking rather than RCU due to calling sleeping functions within the critical section, and now because it's called by iwlwifi from the mac80211 workqueue that may not use the rtnl because it is flushed under rtnl. (cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046) I think, therefore, that we should take a step back, remove it entirely for now and add the small feature it provided properly. For suspend and resume we will need to introduce new hooks, and for the case where the firmware was reset the driver will probably simply just pretend it has done a suspend/resume cycle to get mac80211 to reprogram the hardware completely, not just try to connect to the current AP again in station mode. When doing so, we will need to take into account locking issues and possibly defer to schedule_work from within mac80211 for the resume operation, while the suspend operation must be done directly. Proper suspend/resume should also not necessarily try to reconnect to the current AP, the time spent in suspend may have been short enough to not be disconnected from the AP, mac80211 will detect that the AP went out of range quickly if it did, and if the association is lost then the AP will disassoc as soon as a data frame is sent. We might also take into account WWOL then, and have mac80211 program the hardware into such a mode where it is available and requested. Signed-off-by: Johannes Berg Signed-off-by: John W.

Since there's 8KB A-MPDU support, crossing 4k boundaries didn't seem like something the device would fail with, but when I looked into the function for a minute anyway I stumbled over this little gem: BUG_ON(rxb->dma_addr & (~DMA_BIT_MASK(36) & 0xff)); Clearly, that is a totally bogus check, one would hope the compiler removes it entirely. (Think about it) After fixing it, I obviously ran into it, nothing guarantees the alignment the way you want it, because of the way skbs and their headroom are allocated. I won't explain that here nor double-check that I'm right, that goes beyond what most of the CC'ed people care about. So then I came up with the patch below, and so far my system has survived minutes with 64K pages, when it would previously fail in seconds. And I haven't seen a single instance of the TX bug either. But when you see the patch it'll be pretty obvious to you why. This should fix the following reported kernel bugs: http://bugzilla.kernel.org/show_bug.cgi?id=11596 http://bugzilla.kernel.org/show_bug.cgi?id=11393 http://bugzilla.kernel.org/show_bug.cgi?id=11983 I haven't checked if there are any elsewhere, but I suppose RHBZ will have a few instances too... I'd like to ask anyone who is CC'ed (those are people I know ran into the bug) to try this patch. I am convinced that this patch is correct in spirit, but I haven't understood why, for example, there are so many unmap calls. I'm not entirely convinced that this is the only bug leading to the TX reply errors. Signed-off-by: Johannes Berg Signed-off-by: John W.

This patch simplifies the code and corrects the usage. This simplification also makes the code more robust. Here is the correct logic: Given a function that can be traced by dynamic ftrace: If the function is not to be traced, disable it if it was enabled. (this is if the function is in the set_ftrace_notrace file) (filter is on if there exists any functions in set_ftrace_filter file) If the filter is on, and we are enabling functions: If the function is in set_ftrace_filter, enable it if it is not already enabled. If the function is not in set_ftrace_filter, disable it if it is not already disabled. Otherwise, if the filter is off and we are enabling function tracing: Enable the function if it is not already enabled. Otherwise, if we are disabling function tracing: Disable the function if it is not already disabled. This code now sets or clears the ENABLED flag in the record, and at the end it will enable the function if the flag is set, or disable the function if the flag is cleared. The parameters for the function that does the above logic is also simplified. Instead of passing in confusing "new" and "old" where they might be swapped if the "enabled" flag is not set. The old logic even had one of the above always NULL and had to be filled in. The new logic simply passes in one parameter called "nop". A "call" is calculated in the code, and at the end of the logic, when we know we need to either disable or enable the function, we can then use the "nop" and "call" properly. This code is more robust than the previous version.

But, genphy_restart_aneg() doesn't just restart aneg, it may also *enable* aneg or un-isolate the PHY from the MII (those functions are controlled by the same register). The code to avoid calling genphy_restart_aneg() didn't consider this. So, modify genphy_config_aneg() to also check if the PHY needs to have aneg enabled or be un-isolated before deciding not to restart aneg. This caused a problem with certain Davicom PHYs, as that driver isolates the PHY (why?) before calling genphy_config_aneg() and expects the PHY to be un-isolated by that function.

In ipc_addid(), the newly allocated ipc structure is inserted into the ipcs tree (i.e made visible to readers) without locking it. This is not correct since its initialization continues after it has been inserted in the tree. This patch moves the ipc structure lock initialization + locking before the actual insertion.

The addition of this system call matches analogous changes in 2.6.27 (dup3(), evenfd2(), signalfd4(), inotify_init1(), epoll_create1(), pipe2()) which added new system calls that differed from analogous traditional system calls in adding a flags argument that can be used to access additional functionality. The accept4() system call is exactly the same as accept(), except that it adds a flags bit-mask argument. Two flags are initially implemented. (Most of the new system calls in 2.6.27 also had both of these flags.) SOCK_CLOEXEC causes the close-on-exec (FD_CLOEXEC) flag to be enabled for the new file descriptor returned by accept4(). This is a useful security feature to avoid leaking information in a multithreaded program where one thread is doing an accept() at the same time as another thread is doing a fork() plus exec(). More details here: http://udrepper.livejournal.com/20407.html "Secure File Descriptor Handling", Ulrich Drepper). The other flag is SOCK_NONBLOCK, which causes the O_NONBLOCK flag to be enabled on the new open file description created by accept4(). (This flag is merely a convenience, saving the use of additional calls fcntl(F_GETFL) and fcntl (F_SETFL) to achieve the same result. Here's a test program. Works on x86-32. Should work on x86-64, but I (mtk) don't have a system to hand to test with. It tests accept4() with each of the four possible combinations of SOCK_CLOEXEC and SOCK_NONBLOCK set/clear in 'flags', and verifies that the appropriate flags are set on the file descriptor/open file description returned by accept4(). I tested Ulrich's patch in this thread by applying against 2.6.28-rc2, and it passes according to my test program. /* test_accept4.c Copyright (C) 2008, Linux Foundation, written by Michael Kerrisk Licensed under the GNU GPLv2 or later. */ #define _GNU_SOURCE #include #include #include #include #include #include #include #include #define PORT_NUM 33333 #define die(msg) do { perror(msg); exit(EXIT_FAILURE); } while (0) /**********************************************************************/ /* The following is what we need until glibc gets a wrapper for accept4() */ /* Flags for socket(), socketpair(), accept4() */ #ifndef SOCK_CLOEXEC #define SOCK_CLOEXEC O_CLOEXEC #endif #ifndef SOCK_NONBLOCK #define SOCK_NONBLOCK O_NONBLOCK #endif #ifdef __x86_64__ #define SYS_accept4 288 #elif __i386__ #define USE_SOCKETCALL 1 #define SYS_ACCEPT4 18 #else #error "Sorry -- don't know the syscall # on this architecture" #endif static int accept4(int fd, struct sockaddr *sockaddr, socklen_t *addrlen, int flags) { printf("Calling accept4(): flags = %x", flags); if (flags != 0) { printf(" ("); if (flags & SOCK_CLOEXEC) printf("SOCK_CLOEXEC"); if ((flags & SOCK_CLOEXEC) && (flags & SOCK_NONBLOCK)) printf(" "); if (flags & SOCK_NONBLOCK) printf("SOCK_NONBLOCK"); printf(")"); } printf("\n"); #if USE_SOCKETCALL long args[6]; args[0] = fd; args[1] = (long) sockaddr; args[2] = (long) addrlen; args[3] = flags; return syscall(SYS_socketcall, SYS_ACCEPT4, args); #else return syscall(SYS_accept4, fd, sockaddr, addrlen, flags); #endif } /**********************************************************************/ static int do_test(int lfd, struct sockaddr_in *conn_addr, int closeonexec_flag, int nonblock_flag) { int connfd, acceptfd; int fdf, flf, fdf_pass, flf_pass; struct sockaddr_in claddr; socklen_t addrlen; printf("=======================================\n"); connfd = socket(AF_INET, SOCK_STREAM, 0); if (connfd == -1) die("socket"); if (connect(connfd, (struct sockaddr *) conn_addr, sizeof(struct sockaddr_in)) == -1) die("connect"); addrlen = sizeof(struct sockaddr_in); acceptfd = accept4(lfd, (struct sockaddr *) &claddr, &addrlen, closeonexec_flag | nonblock_flag); if (acceptfd == -1) { perror("accept4()"); close(connfd); return 0; } fdf = fcntl(acceptfd, F_GETFD); if (fdf == -1) die("fcntl:F_GETFD"); fdf_pass = ((fdf & FD_CLOEXEC) != 0) == ((closeonexec_flag & SOCK_CLOEXEC) != 0); printf("Close-on-exec flag is %sset (%s); ", (fdf & FD_CLOEXEC) ?

SPI transmit and receive buffers are allowed to be the same or to overlap. However, this driver fails if such overlap is attempted in DMA mode because it maps the rx and tx buffers in the wrong order. By mapping DMA_FROM_DEVICE (read) before DMA_TO_DEVICE (write), it invalidates the cache before flushing it, thus discarding data which should have been transmitted. The patch corrects the order of mapping. This bug exists in all versions of pxa2xx_spi.c; similar bugs are in the drivers for two other SPI controllers (au1500, imx). A version of this patch has been tested on kernel 2.6.20 using verification of loopback data with: random transfer length, random bits-per-word, random positive offsets (both larger and smaller than transfer length) between the start of the rx and tx buffers, and varying clock rates.

These errors are what I would expect to see if crypt_stat->key were split between two separate pages. eCryptfs should not assume that any of the memory sent through virt_to_scatterlist() is all contained in a single page, and so this patch allocates two scatterlist structs instead of one when processing keys. I have received confirmation from one person affected by this bug that this patch resolves the issue for him, and so I am submitting it for inclusion in a future stable release. Note that virt_to_scatterlist() runs sg_init_table() on the scatterlist structs passed to it, so the calls to sg_init_table() in decrypt_passphrase_encrypted_session_key() are redundant.

The reason is there are areas which are lazily freed, and could be possibly freed now. However, current implementation start searching the tree from the last failing address, which is pretty much by definition at the end of address space. So, we fail. The proposal of this patch is to restart the search from the beginning of the requested vstart address. This fixes the regression in running KVM virtual machines for me, described in http://lkml.org/lkml/2008/10/28/349, caused by commit db64fe02258f1507e13fe5212a989922323685ce.

It has following lock sequence. cgroup_mutex (cgroup_rmdir) -> pre_destroy -> mem_cgroup_pre_destroy-> force_empty -> cpu_hotplug.lock. (lru_add_drain_all-> schedule_work-> get_online_cpus) But, cpuset has following. cpu_hotplug.lock (call notifier) -> cgroup_mutex. (within notifier) Then, this lock sequence should be fixed. Considering how pre_destroy works, it's not necessary to holding cgroup_mutex() while calling it. As a side effect, we don't have to wait at this mutex while memcg's force_empty works.(it can be long when there are tons of pages.)

The USB subsystem hang symptom is observed when the system has multiple USB devices connected to it. In some cases a USB hub may be required to observe this symptom. This patch works around the problem by correcting the internal register setting that will help by changing the behavior of the internal logic to avoid the USB subsystem hang issue. The change in the behavior of the logic does not impact the normal operation of the USB subsystem.

But since translate_usr_offset() returns -1 for invalid offsets, addr can now get the value 0xffffffff which then fails the next return-value sanity check and thus the kernel tries to access invalid memory: if (addr < 0) break; Fix this bug by modifying translate_usr_offset() to take and return values of type compat_ulong_t, and by returning the value "sizeof(struct pt_regs)" as an error indicator. Additionally change the sanity check to check for return values for >= sizeof(struct pt_regs). This patch survived my compile and run-tests.

Eg: alarm(1); write(fd, some_spu_psmap_register_address, 4); - the write's copy_from_user will fault on the ps mapping, and signal_pending will be non-zero. Because returning from the fault handler will never clear TIF_SIGPENDING, so we'll just keep faulting, resulting in an unkillable process using 100% of CPU.

When printing records with seq_printf in t_show, if the read buffer has overruned by the current record, then this record won't be printed to user space through read buffer, it will just be dropped in this printing. When next printing, t_start should return the "*pos"th record, which is the one dropped by previous printing, but it just returns (m->private + *pos)th record. Here we use a more sane method to implement seq_operations which can be found in kernel code. Thus we needn't initialize m->private. About testing, it's not easy to overrun read buffer, but we can use seq_printf to print more padding bytes in t_show, then it's easy to check whether or not records are lost. This commit has been tested on both condition of overrun and non overrun.

But because bulk-read is just an optimization, UBIFS keeps working fine. Supress the warning by passing __GFP_NOWARN option to 'kmalloc()'. This patch also introduces a macro for the magic 128KiB constant. This is just neater. Note, this is not really fixes the problem we had, but just hides the warnings.

The allocation starts failing often when the memory gets fragmented. UBIFS still works fine in this case, because it falls-back to standard (non-optimized) read method, though. This patch teaches bulk-read to allocate exactly the amount of memory it needs, instead of allocating 128KiB every time. This patch is also a preparation to the further fix where we'll have a pre-allocated bulk-read buffer as well. For example, now the @bu object is prepared in 'ubifs_bulk_read()', so we could path either pre-allocated or allocated information to 'ubifs_do_bulk_read()' later. Or teaching 'ubifs_do_bulk_read()' not to allocate 'bu->buf' if it is already there.

I compiled a kernel with the PCMCIA-ID for the netgear card moved to axnet_cs from pcnet_cs which worked. I then contacted sidux-kernel maintainer Stefan Lippers-Hollmann who turned the info into this patch and integrated it into the kernel: This works for me and AFAIK there were no reports of any breakage for other devices on sidux-support. This looks like a trivial patch, but since I have very limited experience with kernel modifications I might be woefully wrong there. But if there are no side effects of this patch, is it possible to get it into the official kernel?

Looking at tcp_current_mss (and the preceding comment) I even think this was the original intention. However, this approach is insufficient, because TSO/GSO is turned off only for newly created frames, not for frames which were already pending at the arrival of a message with MSG_OOB set. These frames were created when TSO/GSO was enabled, so they may be large, and they will have the urgent pointer set in tcp_transmit_skb(). With this patch, such large packets will be fragmented again before going to the transmit routine. As a side note, at least the following NICs are known to screw up the urgent pointer in the TCP header when doing TSO: Intel 82566MM (PCI ID 8086:1049) Intel 82566DC (PCI ID 8086:104b) Intel 82541GI (PCI ID 8086:1076) Broadcom NetXtreme II BCM5708 (PCI ID 14e4:164c) Signed-off-by: Petr Tesarik Signed-off-by: David S.

The detection is now fixed by using the ring buffer API. When mmiotrace detects a buffer overrun, it will report the number of lost events.

Often we do things like put BUG() in the default clause of a case statement. Since it was not declared __noreturn, this could sometimes lead to bogus compiler warnings that variables were used uninitialized. There is a small problem in that we have to put a magic while(1); loop to fool GCC into really thinking it is noreturn. This makes the new BUG() function 3 instructions long instead of just 1, but I think it is worth it as it is now unnecessary to do extra work to silence the 'used uninitialized' warnings. I also re-wrote BUG_ON so that if it is given a constant condition, it just does BUG() instead of loading a constant value in to a register and testing it.

Bruce Fields" Date: Mon, 24 Nov 2008 10:32:46 -0600 Subject: nfsd: use of unitialized list head on error exit in nfs4recover.c Thanks to Matthew Dodd for this bug report: A file label issue while running SELinux in MLS mode provoked the following bug, which is a result of use before init on a 'struct list_head'. In nfsd4_list_rec_dir() if the call to dentry_open() fails the 'goto out' skips INIT_LIST_HEAD() which results in the normally improbable case where list_entry() returns NULL. Trace follows.

For client-side nlm_host entries, both are always AF_UNSPEC, so this check is unnecessary. Since commit 781b61a6, which added support for AF_INET6 addresses to nlm_cmp_addr(), nlm_cmp_addr() now returns FALSE for AF_UNSPEC addresses, which causes nlm_lookup_host() to create a fresh nlm_host entry every time it is called on the client. These extra entries will eventually expire once the server is unmounted, so the impact of this regression, introduced with lockd IPv6 support in 2.6.28, should be minor. We could fix this by adding an arm in nlm_cmp_addr() for AF_UNSPEC addresses, but really, nlm_lookup_host() shouldn't be matching on the srcaddr field for client-side nlm_host lookups.

The pipestat fields affect reporting of all vblank-related interrupts, so we have to reset them during the irq_handler, and while enabling vblank interrupts. Otherwise, if a pipe status field had been set to non-zero before enabling reporting, we would never see an interrupt again. This patch adds i915_enable_pipestat and i915_disable_pipestat to abstract out the steps needed to change the reported interrupts.

The IMR masking was a technique recommended for avoiding getting stuck with no interrupts generated again in MSI mode. It kept new IIR bits from getting set between the IIR read and the IIR write, which would have otherwise prevented an MSI from ever getting generated again. However, this caused a problem for vblank as the IMR mask would keep the pipe event interrupt from getting reflected in IIR, even after the IMR mask was brought back down. Instead, just check the state of IIR after we ack the interrupts we're going to handle, and restart if we didn't get IIR all the way to zero.

Miller, empty packet can be transmitted on connected socket for datagram protocols. However, this patch broke a high level application using ROSE network protocol with connected datagram. Bulletin Board Stations perform bulletins forwarding between BBS stations via ROSE network using a forward protocol. Now, if for some reason, a buffer in the application software happens to be empty at a specific moment, ROSE sends an empty packet via unfiltered packet socket. When received, this ROSE packet introduces perturbations of data exchange of BBS forwarding, for the application message forwarding protocol is waiting for something else. We agree that a more careful programming of the application protocol would avoid this situation and we are willing to debug it. But, as an empty frame is no use and does not have any meaning for ROSE protocol, we may consider filtering zero length data both when sending and receiving socket data. The proposed patch repaired BBS data exchange through ROSE network that were broken since 2.6.22.11 kernel. Signed-off-by: Bernard Pidoux Signed-off-by: David S.

As a consequence this can cause a panic during boot (potentially with all recent kernel versions -- at least I have reproduced it with various 2.6.27 kernels and with the current .28 series), as an example: powernow-k8: Found 1 AMD Turion(tm)X2 Ultra DualCore Mobile ZM-82 processors (2 \ ) powernow-k8: 0 : pstate 0 (2200 MHz) powernow-k8: 1 : pstate 1 (1100 MHz) powernow-k8: 2 : pstate 2 (600 MHz) BUG: unable to handle kernel paging request at ffff88086e7528b8 IP: [] cpufreq_stats_update+0x4a/0x5f PGD 202063 PUD 0 Oops: 0002 [#1] SMP last sysfs file: CPU 1 Modules linked in: Pid: 1, comm: swapper Not tainted 2.6.28-rc3-dirty #16 RIP: 0010:[] [] cpufreq_stats_update+0x4a/0\ f Synaptics claims to have extended capabilities, but I'm not able to read them.<6\ 6 RAX: 0000000000000000 RBX: 0000000000000001 RCX: ffff88006e7528c0 RDX: 00000000ffffffff RSI: ffff88006e54af00 RDI: ffffffff808f056c RBP: 00000000fffee697 R08: 0000000000000003 R09: ffff88006e73f080 R10: 0000000000000001 R11: 00000000002191c0 R12: ffff88006fb83c10 R13: 00000000ffffffff R14: 0000000000000001 R15: 0000000000000000 FS: 0000000000000000(0000) GS:ffff88006fb50740(0000) knlGS:0000000000000000 Unable to initialize Synaptics hardware.

In short, aftereffect of the wrong P-state is that cpufreq_stats_update() uses "-1" as index for some array in cpufreq_stats_update (unsigned int cpu) { ... if (stat->time_in_state) stat->time_in_state[stat->last_index] = cputime64_add(stat->time_in_state[stat->last_index], cputime_sub(cur_time, stat->last_time)); ... } Fortunately, the wrong P-state value is returned only if the core is in P-state 0. This fix solves the problem by detecting the out-of-range P-state, ignoring it, and using "0" instead.

I asked around, and he's right, there may be platforms that do not allow passing such such an address to the DMA API functions.

We were pci_unmap_single()'ing less bytes than what we called for with pci_map_single() and as such we were starving the swiotlb from its 64MB amount of bounce buffers. We remain consistent and now always use sc->rxbufsize for RX. While at it we update the beacon DMA maps as well to only use the data portion of the skb, previous to this we were pci_map_single()'ing more data for beaconing than what we tell the hardware it can use, therefore pushing more iotlb abuse. Still not sure why this is so easily triggerable on MacBook Pro 3.1, it may be the hardware configuration tends to use more memory > 3GB mark for DMA.

When zapping a high level table, kvm_mmu_page_unlink_children fails to remove the parent_pte link. For that to happen, the child must be unreachable via the shadow tree, which can happen in shadow_walk_entry if the guest pte was modified in between walk() and fetch().

Rather than passing the page offset of the start of the write, we needed to pass the offset of the beginning of the page. This was reliably showing up as data corruption in the fsx-linux test from LTP. It also became evident that this code was occasionally doing unnecessary read calls. Optimize those away by using the PG_checked flag to indicate that the unwritten part of the page has been initialized.

A simple testcase is available here: http://gsyprf10.external.hp.com/~deller/crash.tgz The problem is introduced by the fact, that the handle_interruption() crash handler calls the show_regs() function, which in turn tries to unwind the stack by calling parisc_show_stack(). Since the stack contains userspace addresses, a try to unwind the stack is dangerous and useless and leads to the crash. The fix is trivial: For userspace processes a) avoid to unwind the stack, and b) avoid to resolve userspace addresses to kernel symbol names. While touching this code, I converted print_symbol() to %pS printk formats and made parisc_show_stack() static. An initial patch for this was written by Kyle McMartin back in August: http://marc.info/?l=linux-parisc&m=121805168830283&w=2 Compile and run-tested with a 64bit parisc kernel.

The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

Wysocki" Date: Wed, 26 Nov 2008 17:53:13 -0500 Subject: ACPI suspend: Blacklist boxes that require us to set SCI_EN directly on resume Some Apple boxes evidently require us to set SCI_EN on resume directly, because if we don't do that, they hung somewhere in the resume code path. Moreover, on these boxes it is not sufficient to use acpi_enable() to turn ACPI on during resume. All of this is against the ACPI specification which states that (1) the BIOS is supposed to return from the S3 sleep state with ACPI enabled (SCI_EN set) and (2) the SCI_EN bit is owned by the hardware and we are not supposed to change it. For this reason, blacklist the affected systems so that the SCI_EN bit is set during resume on them. [NOTE: Unconditional setting SCI_EN for all system on resume doesn't work, because it makes some other systems crash (that's to be expected). Also, it is not entirely clear right now if all of the Apple boxes require this workaround.] This patch fixes the recent regression tracked as http://bugzilla.kernel.org/show_bug.cgi?id=12038 Signed-off-by: Rafael J.

It is possible for fan_suspend() to fail to properly initialize fan_control_desired_level as required by fan_resume(), resulting on the fan always being set to level 7 on resume if the user didn't touch the fan controller. In order to get fan sleep/resume handling to work right: 1. Fix the fan_suspend handling of the T43 firmware quirk. If it is still undefined, we didn't touch the fan yet and that means we have no business doing it on resume. 2. Store the fan level on its own variable to avoid any possible issues with hijacking fan_control_desired_level (which isn't supposed to have anything other than 0-7 in it, anyway). 3. Change the fan_resume code to me more straightforward to understand (although we DO optimize the boolean logic there, otherwise it looks disgusting). 4. Add comments to help understand what the code is supposed to be doing. 5. Change fan_set_level to be less strict about how auto and full-speed modes are requested. http://bugzilla.kernel.org/show_bug.cgi?id=11982 Signed-off-by: Henrique de Moraes Holschuh Reported-by: Tino Keitel Signed-off-by: Len Brown --- drivers/misc/thinkpad_acpi.c | 57 ++++++++++++++++++++++++++++++++++---------- 1 file changed, 45 insertions(+), 12 deletions(-) diff --git a/drivers/misc/thinkpad_acpi.c b/drivers/misc/thinkpad_acpi.c index 7a4a26b0edd..899766e16fa 100644 --- a/drivers/misc/thinkpad_acpi.c +++ b/drivers/misc/thinkpad_acpi.c @@ -5318,6 +5318,7 @@ static enum fan_control_commands fan_control_commands; static u8 fan_control_initial_status; static u8 fan_control_desired_level; +static u8 fan_control_resume_level; static int fan_watchdog_maxinterval; static struct mutex fan_mutex; @@ -5440,8 +5441,8 @@ static int fan_set_level(int level) case TPACPI_FAN_WR_ACPI_FANS: case TPACPI_FAN_WR_TPEC: - if ((level != TP_EC_FAN_AUTO) && - (level != TP_EC_FAN_FULLSPEED) && + if (!(level & TP_EC_FAN_AUTO) && + !(level & TP_EC_FAN_FULLSPEED) && ((level < 0) || (level > 7))) return -EINVAL; @@ -6005,38 +6006,67 @@ static void fan_exit(void) static void fan_suspend(pm_message_t state) { + int rc; + if (!fan_control_allowed) return; /* Store fan status in cache */ - fan_get_status_safe(NULL); + fan_control_resume_level = 0; + rc = fan_get_status_safe(&fan_control_resume_level); + if (rc < 0) + printk(TPACPI_NOTICE + "failed to read fan level for later " + "restore during resume: %d\n", rc); + + /* if it is undefined, don't attempt to restore it. + * KEEP THIS LAST */ if (tp_features.fan_ctrl_status_undef) - fan_control_desired_level = TP_EC_FAN_AUTO; + fan_control_resume_level = 0; } static void fan_resume(void) { - u8 saved_fan_level; u8 current_level = 7; bool do_set = false; + int rc; /* DSDT *always* updates status on resume */ tp_features.fan_ctrl_status_undef = 0; - saved_fan_level = fan_control_desired_level; if (!fan_control_allowed || + !fan_control_resume_level || (fan_get_status_safe(¤t_level) < 0)) return; switch (fan_control_access_mode) { case TPACPI_FAN_WR_ACPI_SFAN: - do_set = (saved_fan_level > current_level); + /* never decrease fan level */ + do_set = (fan_control_resume_level > current_level); break; case TPACPI_FAN_WR_ACPI_FANS: case TPACPI_FAN_WR_TPEC: - do_set = ((saved_fan_level & TP_EC_FAN_FULLSPEED) || - (saved_fan_level == 7 && - !(current_level & TP_EC_FAN_FULLSPEED))); + /* never decrease fan level, scale is: + * TP_EC_FAN_FULLSPEED > 7 >= TP_EC_FAN_AUTO + * + * We expect the firmware to set either 7 or AUTO, but we + * handle FULLSPEED out of paranoia. + * + * So, we can safely only restore FULLSPEED or 7, anything + * else could slow the fan.

But collect_syscall() can be called for any sleeping task, the result of syscall_get_nr() in general is completely bogus. To make syscall_get_nr() work for any sleeping task the traps field in pt_regs is replace with svcnr - the system call number the process is executing. If svcnr == 0 the process is not on a system call path. The syscall_get_arguments and syscall_set_arguments use regs->gprs[2] for the first system call parameter. This is incorrect since gprs[2] may have been overwritten with the system call number if the call chain includes do_syscall_trace_enter. Use regs->orig_gprs2 instead.

The s390 implementation of sched_clock uses the store clock instruction and subtracts jiffies_timer_cc. jiffies_timer_cc is a local variable in arch/s390/kernel/time.c and only used for sched_clock and monotonic clock. For historical reasons there is an offset on that value. With todays code this offset is unnecessary. By removing that offset we can get a sched_clock which returns the nanoseconds after time_init. This improves CONFIG_PRINTK_TIME. Since sched_clock is the only user, I have also renamed jiffies_timer_cc to sched_clock_base_cc. In addition, the local variable init_timer_cc is redundant and can be romved as well.

But we also need these macros when we have SWIOTLB, VT-d or AMD IOMMU in the kernel. Since we always compile at least with SWIOTLB we can define these macros always. This patch is also for stable backport for the same reason the SWIOTLB default selection patch is.

Call invalidate_inode_buffers() so that the list is properly cleaned-up before we return from udf_clear_inode(). This is ugly and suggest that we should cleanup preallocation earlier than in clear_inode() but currently there's no such call available since drop_inode() is called under inode lock and thus is unusable for disk operations.

This avoids having to consider any userspace aliases from this operation. However, when highmem is enabled, kmap_atomic() have to setup mappings. The copy_user_highpage() and clear_user_highpage() call these functions before delegating the copies to copy_user_page() and clear_user_page(). The effect of this is that each of the *_user_highpage() functions setup their own kmap mapping, followed by the *_user_page() functions setting up another mapping. This is rather wasteful. Thankfully, copy_user_highpage() can be overriden by architectures by defining __HAVE_ARCH_COPY_USER_HIGHPAGE. However, replacement of clear_user_highpage() is more difficult because its inline definition is not conditional. It seems that you're expected to define __HAVE_ARCH_ALLOC_ZEROED_USER_HIGHPAGE and provide a replacement __alloc_zeroed_user_highpage() implementation instead. The allocation itself is fine, so we don't want to override that. What we really want to do is to override clear_user_highpage() with our own version which doesn't kmap_atomic() unnecessarily. Other VIPT architectures (PARISC and SH) would also like to override this function as well.

More interesting, in the same failure case handling, it calls the exit function, which also frees the rfkill state, but after stopping the polling. If the race happens, a NULL pointer is passed to rfkill_force_state() which then causes a nice dereference. Fix the race by just not doing the too-early freeing of the rfkill state. This appears to be the cause of a hot issue on kerneloops.org; while I have no solid evidence of that this patch will fix the issue, the race appears rather real.

As part of that support, SET_PORT is invoked to set the port type during driver startup. However, as a side-effect, for IB ports the invocation of this command also sets the port's capability mask to zero (losing the default value set by FW). To fix this, get the default ib port capabilities (via a MAD_IFC Port Info query) during driver startup, and save them for use in the mlx4_SET_PORT command when setting the port-type to Infiniband. This patch fixes problems with subnet manager (SM) failover such as , which occurred because the IsTrapSupported bit in the capability mask was zeroed.

It is caused by commit 8f64e1f2d1e09267ac926e15090fd505c1c0cbcb ("powerpc: Reserve in bootmem lmb reserved regions that cross NUMA nodes"). The problem is that Jon took a loop which was (in pseudocode): for_each_node(nid) NODE_DATA(nid) = careful_alloc(nid); setup_bootmem(nid); reserve_node_bootmem(nid); and broke it up into: for_each_node(nid) NODE_DATA(nid) = careful_alloc(nid); setup_bootmem(nid); for_each_node(nid) reserve_node_bootmem(nid); The issue comes in when the 'careful_alloc()' is called on a node with no memory. It falls back to using bootmem from a previously-initialized node. But, bootmem has not yet been reserved when Jon's patch is applied. It gives back bogus memory (0xc000000000000000) and pukes later in boot. The following patch collapses the loop back together. It also breaks the mark_reserved_regions_for_nid() code out into a function and adds some comments. I think a huge part of introducing this bug is because for loop was too long and hard to read.

Each MSI vector gets written into a FIFO buffer in main memory using DMA, and that DMA access is normally flushed by the actual interrupt packet on the IOIF. An MMIO register in the MSIC holds the position of the last entry in the FIFO buffer that was written. However, reading that position does not flush the DMA, so that we can observe stale data in the buffer. In a stress test, we have observed the DMA to arrive up to 14 microseconds after reading the register. This patch works around this problem by retrying the access to the FIFO buffer. We can reliably detect the conditioning by writing an invalid MSI vector into the FIFO buffer after reading from it, assuming that all MSIs we get are valid. After detecting an invalid MSI vector, we udelay(1) in the interrupt cascade for up to 100 times before giving up.

It turns out that this is the result of mpic_init trying to set affinity of each interrupt vector to the current boot CPU. As far as I can tell, the same problem is likely to exist on any secondary MPIC, because they have to deliver interrupts to the first output all the time. There are two potential solutions for this: either not set up affinity at all for secondary MPICs, or assume that a single CPU output is connected to the upstream interrupt controller and hardcode affinity to that per architecture. This patch implements the second approach, defaulting to the first output. Currently, all known secondary MPICs are routed to their upstream port using the first destination, so we hardcode that.

Since CR0.SO is used as the error indication from the system call, this means that all system calls appear to fail. The reason is that the workaround for the timebase bug on Cell uses a compare instruction. With CONFIG_VIRT_CPU_ACCOUNTING = y, the ACCOUNT_CPU_USER_ENTRY macro reads the timebase, so we end up doing a compare instruction, which copies XER.SO to CR0.SO. Since we were doing this in the system call entry patch after clearing CR0.SO but before saving the CR, this meant that the saved CR image had CR0.SO set if XER.SO was set on entry. This fixes it by moving the clearing of CR0.SO to after the ACCOUNT_CPU_USER_ENTRY call in the system call entry path.

The panic kernel either does not start at all or crash in various places. The problem is that hpwdt_pretimeout is registered with register_die_notifier() with the highest possible priority. Because it returns NOTIFY_STOP, the crash_nmi_callback which is also registered with register_die_notifier() is never executed. This causes the shutdown of other CPUs to fail. Reverting the order is no option: The crash_nmi_callback executes HLT and so never returns normally. Because of that, it must be executed as last notifier, which currently is done. So, that patch returns NOTIFY_OK to keep the crash_nmi_callback executed.

As a result, if any app used resize CQ repeatedly, all MTTs were eventually exhausted, which led to all memory registration operations failing until the driver is reloaded. Once the RESIZE_CQ command returns successfully from FW, FW no longer accesses the old CQ buffer, so it is safe to deallocate the MTT entries used by the old CQ buffer. Finally, if the RESIZE_CQ command fails, the MTTs allocated for the new CQEs buffer also need to be de-allocated. This fixes .

We determined that the problem was most likely due to a cache aliasing issue. flush_cache_vunmap was only being called at the moment the page tables were to be taken down, however with lazy unmapping, this can happen after the page has subsequently been freed and allocated for something else. The dangling alias may still have dirty data attached to it. The fix for this problem is to do the cache flushing when the caller has called vunmap -- it would be a bug for them to write anything else to the mapping at that point. That appeared to solve Jim's problems.

While memory hotplug allocate/free memmap, page_cgroup doesn't free page_cgroup at OFFLINE when page_cgroup is allocated via bootomem. (Because freeing bootmem requires special care.) Then, if page_cgroup is allocated by bootmem and memmap is freed/allocated by memory hotplug, page_cgroup->page == page is no longer true. But current MEM_ONLINE handler doesn't check it and update page_cgroup->page if it's not necessary to allocate page_cgroup. (This was not found because memmap is not freed if SPARSEMEM_VMEMMAP is y.) And I noticed that MEM_ONLINE can be called against "part of section". So, freeing page_cgroup at CANCEL_ONLINE will cause trouble. (freeing used page_cgroup) Don't rollback at CANCEL. One more, current memory hotplug notifier is stopped by slub because it sets NOTIFY_STOP_MASK to return vaule. So, page_cgroup's callback never be called. (low priority than slub now.) I think this slub's behavior is not intentional(BUG). and fixes it. Another way to be considered about page_cgroup allocation: - free page_cgroup at OFFLINE even if it's from bootmem and remove specieal handler. But it requires more changes.

Vegard Nossum reported a very simple program (a modified version attached) that can make a normal user to request a pretty large amount of kernel memory, well within the its maximum number of fds. To solve such problem, default limits are now imposed, and /proc based configuration has been introduced. A new directory has been created, named /proc/sys/fs/epoll/ and inside there, there are two configuration points: max_user_instances = Maximum number of devices - per user max_user_watches = Maximum number of "watched" fds - per user The current default for "max_user_watches" limits the memory used by epoll to store "watches", to 1/32 of the amount of the low RAM. As example, a 256MB 32bit machine, will have "max_user_watches" set to roughly 90000. That should be enough to not break existing heavy epoll users. The default value for "max_user_instances" is set to 128, that should be enough too. This also changes the userspace, because a new error code can now come out from EPOLL_CTL_ADD (-ENOSPC). The EMFILE from epoll_create() was already listed, so that should be ok.

However this broke the fbcon timeout blanking. If you use a driver that defines ->fb_blank operation and at the same time that driver relies on other driver (e.g. backlight or lcd class) to blank the screen, when the fbcon times out and tries to blank the fb, it will call only fb driver blanker and won't notify the other driver. Thus FB output is disabled, but the screen isn't blanked. Restore fbcon blanking and at the same time apply the proper fix for the above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are already called through notification from fb_blank, thus we don't have to blank the fb again.

Also i82975x_edac code seems to have the same module removal bugs as in i82875p_edac. The problems were: 1. In module removal i82875p_remove_one() is never called. Variable i82875p_registered is newer changed from 1, which guarantees i82875p_remove_one() is not called (and even if it were called, it would be called in wrong order). As a result, the edac_mc workque is not stopped and keeps probing.

The kobject refcount of mci drops to 0 and mci is freed. After this mci is accessed via debug print and i82875p_remove_one() still uses mci->pvt and tries to free mci again with edac_mc_free(). The fix for this is add kobject_get(&mci->edac_mci_kobj) after edac_mc_alloc(). Then the mci is still available after returning from edac_mc_del_mc() with refcount 1, and mci->pvt is still available. When i82875p_remove_one() finally calls edac_mc_free(), this will cause kobject_put() and mci is released properly.

In order to achieve this: * Add ide_pci_is_in_compatibility_mode() inline helper to . * Add IDE_HFLAG_BROKEN_ALTSTATUS host flag and set it in amd74xx host driver for nVidia controllers in Compatibility Mode. * Teach actual_try_to_identify() and drive_is_ready() about the new flag. This fixes the regression caused by removal of CONFIG_IDEPCI_SHARE_IRQ config option in 2.6.25 and using AltStatus register unconditionally when available (kernel.org bugs #11659 and #10216). [ Moreover for CONFIG_IDEPCI_SHARE_IRQ=y (which is what most people and distributions use) it never worked correctly. ] Thanks to Remy LABENE and Lars Winterfeld for help with debugging the problem.

This means streaming file IO will increment the recent scanned file statistic, while leaving the recent rotated file statistic alone, driving pageout scanning to the file LRUs.

The bnx2 chips do not support per MSI vector masking. On 5706/5708, new MSI address/data are stored only when the MSI enable bit is toggled. As a result, SMP affinity no longer works in the latest kernel. A more serious problem is that the driver will no longer receive interrupts when the MSI receiving CPU goes offline. The workaround in this patch only addresses the problem of CPU going offline. When that happens, the driver's timer function will detect that it is making no forward progress on pending interrupt events and will recover from it. Eric Dumazet reported the problem.

Barrier code dequeues the original barrier request but doesn't passes the request itself to lower level driver, only broken down proxy requests; however, as the original barrier code goes through the same dequeue path and timeout timer is started on it. If barrier sequence takes long enough, this timer expires but the low level driver has no idea about this request and oops follows. Timeout timer shouldn't have been started on the original barrier request as it never goes through actual IO. This patch unexports elv_dequeue_request(), which has no external user anyway, and makes it operate on elevator proper w/o adding the timer and make blkdev_dequeue_request() call elv_dequeue_request() and add timer.

When stacking devices (LVM over MD over SCSI) some of the request queue parameters are not set up correctly in some cases by default, namely max_segment_size and and seg_boundary mask. If you create MD device over SCSI, these attributes are zeroed. Problem become when there is over this mapping next device-mapper mapping - queue attributes are set in DM this way: request_queue max_segment_size seg_boundary_mask SCSI 65536 0xffffffff MD RAID1 0 0 LVM 65536 -1 (64bit) Unfortunately bio_add_page (resp. bio_phys_segments) calculates number of physical segments according to these parameters. During the generic_make_request() is segment cout recalculated and can increase bio->bi_phys_segments count over the allowed limit. (After bio_clone() in stack operation.) Thi is specially problem in CCISS driver, where it produce OOPS here BUG_ON(creq->nr_phys_segments > MAXSGENTRIES); (MAXSEGENTRIES is 31 by default.) Sometimes even this command is enough to cause oops: dd iflag=direct if=/dev// of=/dev/null bs=128000 count=10 This command generates bios with 250 sectors, allocated in 32 4k-pages (last page uses only 1024 bytes). For LVM layer, it allocates bio with 31 segments (still OK for CCISS), unfortunatelly on lower layer it is recalculated to 32 segments and this violates CCISS restriction and triggers BUG_ON(). The patch tries to fix it by: * initializing attributes above in queue request constructor blk_queue_make_request() * make sure that blk_queue_stack_limits() inherits setting (DM uses its own function to set the limits because it blk_queue_stack_limits() was introduced later. It should probably switch to use generic stack limit function too.) * sets the default seg_boundary value in one place (blkdev.h) * use this mask as default in DM (instead of -1, which differs in 64bit) Bugs related to this: https://bugzilla.redhat.com/show_bug.cgi?id=471639 http://bugzilla.kernel.org/show_bug.cgi?id=8672 Signed-off-by: Milan Broz Reviewed-by: Alasdair G Kergon Cc: Neil Brown Cc: FUJITA Tomonori Cc: Tejun Heo Cc: Mike Miller Signed-off-by: Jens Axboe --- block/blk-core.c | 2 +- block/blk-settings.c | 4 ++++ drivers/md/dm-table.c | 2 +- include/linux/blkdev.h | 2 ++ 4 files changed, 8 insertions(+), 2 deletions(-) diff --git a/block/blk-core.c b/block/blk-core.c index 7a779d7c69c..c36aa98fafa 100644 --- a/block/blk-core.c +++ b/block/blk-core.c @@ -592,7 +592,7 @@ blk_init_queue_node(request_fn_proc *rfn, spinlock_t *lock, int node_id) 1 << QUEUE_FLAG_STACKABLE); q->queue_lock = lock; - blk_queue_segment_boundary(q, 0xffffffff); + blk_queue_segment_boundary(q, BLK_SEG_BOUNDARY_MASK); blk_queue_make_request(q, __make_request); blk_queue_max_segment_size(q, MAX_SEGMENT_SIZE); diff --git a/block/blk-settings.c b/block/blk-settings.c index 41392fbe19f..afa55e14e27 100644 --- a/block/blk-settings.c +++ b/block/blk-settings.c @@ -125,6 +125,9 @@ void blk_queue_make_request(struct request_queue *q, make_request_fn *mfn) q->nr_requests = BLKDEV_MAX_RQ; blk_queue_max_phys_segments(q, MAX_PHYS_SEGMENTS); blk_queue_max_hw_segments(q, MAX_HW_SEGMENTS); + blk_queue_segment_boundary(q, BLK_SEG_BOUNDARY_MASK); + blk_queue_max_segment_size(q, MAX_SEGMENT_SIZE); + q->make_request_fn = mfn; q->backing_dev_info.ra_pages = (VM_MAX_READAHEAD * 1024) / PAGE_CACHE_SIZE; @@ -314,6 +317,7 @@ void blk_queue_stack_limits(struct request_queue *t, struct request_queue *b) /* zero is "infinity" */ t->max_sectors = min_not_zero(t->max_sectors, b->max_sectors); t->max_hw_sectors = min_not_zero(t->max_hw_sectors, b->max_hw_sectors); + t->seg_boundary_mask = min_not_zero(t->seg_boundary_mask, b->seg_boundary_mask); t->max_phys_segments = min(t->max_phys_segments, b->max_phys_segments); t->max_hw_segments = min(t->max_hw_segments, b->max_hw_segments); diff --git a/drivers/md/dm-table.c b/drivers/md/dm-table.c index a63161aec48..04e5fd742c2 100644 --- a/drivers/md/dm-table.c +++ b/drivers/md/dm-table.c @@ -668,7 +668,7 @@ static void check_for_valid_limits(struct io_restrictions *rs) if (!rs->max_segment_size) rs->max_segment_size = MAX_SEGMENT_SIZE; if (!rs->seg_boundary_mask) - rs->seg_boundary_mask = -1; + rs->seg_boundary_mask = BLK_SEG_BOUNDARY_MASK; if (!rs->bounce_pfn) rs->bounce_pfn = -1; } diff --git a/include/linux/blkdev.h b/include/linux/blkdev.h index 9cc7cc5fdce..6dcd30d806c 100644 --- a/include/linux/blkdev.h +++ b/include/linux/blkdev.h @@ -918,6 +918,8 @@ extern void blk_set_cmd_filter_defaults(struct blk_cmd_filter *filter); #define MAX_SEGMENT_SIZE 65536 +#define BLK_SEG_BOUNDARY_MASK 0xFFFFFFFFUL + #define blkdev_entry_to_request(entry) list_entry((entry), struct request, queuelist) static inline int queue_hardsect_size(struct request_queue *q) -- cgit v1.2.3 From 9ea84ad77d635bdb76c9a08f44f21a9af98359ee Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 2 Dec 2008 07:21:21 +0100 Subject: oprofile: fix CPU unplug panic in ppro_stop() If oprofile statically compiled in kernel, a cpu unplug triggers a panic in ppro_stop(), because a NULL pointer is dereferenced.

However, looking at the user-space oprofile code there isn't the matching entry in libop/op_cpu_type.c or the events/unit_mask files in events/i386 directory. The Intel AP-485 says this is a "Intel Pentium M processor model D". Seems like the oprofile kernel driver should be identifying the processor as "i386/p6_mobile" The driver identification code doesn't look quite right in nmi_init.c http://git.kernel.org/?p=linux/kernel/git/sfr/linux-next.git;a=blob;f=arch/x86/oprofile/nmi_int.c;h=022cd41ea9b4106e5884277096e80e9088a7c7a9;hb=HEAD has: 409 case 10 ... 13: 410 *cpu_type = "i386/p6"; 411 break; Referring to the Intel AP-485: case 10 and 11 should produce "i386/piii" case 13 should produce "i386/p6_mobile" I didn't see anything for case 12. Something like the attached patch. I don't have a celeron machine to verify that changes in this area of the kernel fix thing. -Will Signed-off-by: William Cohen Tested-by: Alan Jenkins Acked-by: Andi Kleen Signed-off-by: Robert Richter --- arch/x86/oprofile/nmi_int.c | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/arch/x86/oprofile/nmi_int.c b/arch/x86/oprofile/nmi_int.c index 022cd41ea9b..202864ad49a 100644 --- a/arch/x86/oprofile/nmi_int.c +++ b/arch/x86/oprofile/nmi_int.c @@ -401,14 +401,13 @@ static int __init ppro_init(char **cpu_type) *cpu_type = "i386/pii"; break; case 6 ... 8: + case 10 ... 11: *cpu_type = "i386/piii"; break; case 9: + case 13: *cpu_type = "i386/p6_mobile"; break; - case 10 ... 13: - *cpu_type = "i386/p6"; - break; case 14: *cpu_type = "i386/core"; break; -- cgit v1.2.3 From bd7df219202f44e71e2e975a0fb5f76f946c1aef Mon Sep 17 00:00:00 2001 From: "remi.denis-courmont@nokia" Date: Mon, 1 Dec 2008 02:37:20 +0000 Subject: Phonet: do not dump addresses from other namespaces MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Signed-off-by: Rémi Denis-Courmont Signed-off-by: David S.

This bug seemingly caused various random behavior, with Frans Pop reporting that X.org just silently hung at startup and Rafael Wysocki reports the fan spinning with full speed. See http://lkml.org/lkml/2008/12/3/178 http://bugzilla.kernel.org/show_bug.cgi?id=12162 The problem seems to have been triggered by "[WATCHDOG] iTCO_wdt : problem with rebooting on new ICH9 based motherboards" (commit 7cd5b08be3c489df11b559fef210b81133764ad4), but the bogus code existed before that too (in the "supermicro_old_pre_stop()" function), it just apparently never showed up due to different logic.

The emulation code for the pdist instruction uses RS1(insn) for both source registers rs1 and rs2, which is obviously wrong and leads to the instruction doing nothing (the observed problem), and further inspection of the code shows that RS1 uses a shift of 24 and RD a shift of 25, which clearly cannot both be right; examining SPARC documentation indicates the correct shift for RS1 is 14. This patch fixes the bug if single-stepping over the affected instruction in the debugger, but not if the testcase is run standalone. For that, Wind River has another patch I hope they will send as a followup to this patch submission. Signed-off-by: Joseph Myers Signed-off-by: David S.

Basically this reverts "tcp: Do not use TSO/GSO when there is urgent data" (33cf71cee1). It also removes some unnecessary code from tcp_current_mss that didn't work as intented either (could be that something was changed down the road, or it might have been broken since the dawn of time) because it only works once urg is already written while this bug shows up starting from ~64k before the urg point. The retransmissions already are split to mss sized chunks, so only new data sending paths need splitting in case they have a segment otherwise suitable for gso/tso.

Through their great diagnosis, they found that the xtime_nsec value used in update_wall_time was occasionally going negative. After looking through the code for awhile, I realized we have the possibility for an underflow when three conditions are met in update_wall_time(): 1) We have accumulated a second's worth of nanoseconds, so we incremented xtime.tv_sec and appropriately decrement xtime_nsec. (This doesn't cause xtime_nsec to go negative, but it can cause it to be small). 2) The remaining offset value is large, but just slightly less then cycle_interval. 3) clocksource_adjust() is speeding up the clock, causing a corrective amount (compensating for the increase in the multiplier being multiplied against the unaccumulated offset value) to be subtracted from xtime_nsec. This can cause xtime_nsec to underflow. Unfortunately, since we notify the NTP subsystem via second_overflow() whenever we accumulate a full second, and this effects the error accumulation that has already occured, we cannot simply revert the accumulated second from xtime nor move the second accumulation to after the clocksource_adjust call without a change in behavior. This leaves us with (at least) two options: 1) Simply return from clocksource_adjust() without making a change if we notice the adjustment would cause xtime_nsec to go negative. This would work, but I'm concerned that if a large adjustment was needed (due to the error being large), it may be possible to get stuck with an ever increasing error that becomes too large to correct (since it may always force xtime_nsec negative). This may just be paranoia on my part. 2) Catch xtime_nsec if it is negative, then add back the amount its negative to both xtime_nsec and the error. This second method is consistent with how we've handled earlier rounding issues, and also has the benefit that the error being added is always in the oposite direction also always equal or smaller then the correction being applied. So the risk of a corner case where things get out of control is lessened.

Let's move the __fls() code into fls() function directly, and redefine __fls() with the appropriate semantics. While at it, bring a generic __fls() definition for pre ARMv5 too.

At the moment this code leaves ssthresh untouched. However, this means that the vegas congestion control algorithm is effectively unable to reduce cwnd below the ssthresh value (if the vegas update lowers the cwnd below ssthresh, then slow start is activated to raise it back up). One example where this matters is when during slow start cwnd overshoots the link capacity and a flow then exits slow start with ssthresh set to a value above where congestion avoidance would like to adjust it.

One of the things it does is to make READ_IMPLIES_EXEC be set in ->personality if we are running on a CPU that doesn't support the XN ("Execute Never") page table bit or if we are running a binary that needs an executable stack. This exposed a latent bug in ARM's asm/processor.h due to which we'll end up placing the stack at a very low address, where it will bump into the heap on any application that uses significant amount of stack or heap or both, causing many interesting crashes. Fix this by testing the ADDR_LIMIT_32BIT bit in ->personality instead of testing for equality against PER_LINUX_32BIT.

Since the destination may be reused as a source, ensure that it is only mapped once and that it is mapped bidirectionally. This appears to add ugliness on the unmap side in that it always reads back the destination address from the descriptor, but gcc can determine that dma_unmap is a nop and not emit the code that calculates its arguments.

Thus it was a mistake for that commit to remove the handling of NULL returns in the callers. Revert those parts of 440037287c5 which removed the NULL handling. (We could, alternatively, modify all implementations to return -ESTALE instead of NULL, but that proves to require fixing a number of filesystems, and in some cases it's arguably more natural to return NULL.)

Since applying the fix suggested by the errata (disabling MSI), we've had issues with interrupts being stuck on despite IIR being 0 on GM965 hardware. Most reporters of the issue have confirmed that turning MSI back on fixes things, and given the difficulties experienced in getting reliable MSI working on Linux, it's believable that the errata was about software issues and not actual hardware issues.

Miller" Date: Tue, 9 Dec 2008 00:10:11 -0800 Subject: sungem: Make PCS PHY support partially work again. As reported by Hermann Lauer, PCS PHY support in the sungem driver simply doesn't work. When the chip is reset due to open, or some other similar operation, the PCS is reset too but we don't program it back into a running state. The result is no link when the device is brought up. This partially rectifies the situation for the moment, by kicking the PCS after a sungem chip reset so that it will renegotiate and be re-enabled again. The behavior is still a little bit dodgy as the added renegotiate make the link take some time after bringing the interface up, but this is a significant improvement in that things actually work now :-) Based almost entirely upon an initial patch by Hermann.

At present tcp_vegas does separate book-keeping of cwnd based on packet sequence numbers. A mismatch can develop between this book-keeping and tp->snd_cwnd due, for example, to delayed acks acking multiple packets. When vegas transitions to reno operation (e.g. following loss), then this mismatch leads to incorrect behaviour (akin to a cwnd backoff). This seems mostly to affect operation at low cwnds where delayed acking can lead to a significant fraction of cwnd being covered by a single ack, leading to the book-keeping mismatch. This patch modifies the congestion avoidance update to avoid the need for separate book-keeping while leaving vegas congestion avoidance functionally unchanged. A secondary advantage of this modification is that the use of fixed-point (via V_PARAM_SHIFT) and 64 bit arithmetic is no longer necessary, simplifying the code. Some example test measurements with the patched code (confirming no functional change in the congestion avoidance algorithm) can be seen at: http://www.hamilton.ie/doug/vegaspatch/ Signed-off-by: Doug Leith Signed-off-by: David S.

The AUTOFS=y and AUTOFS4=y causes problems with some distros versions of automount. I turned both of those to =m and then followed the default prompts for everything else. I did notice that CONFIG_PNP_DEBUG got changed to CONFIG_PNP_DEBUG_MESSAGES and the default was a =y so I turned that back to a =n.

When starting a cycle post-boot, this doesn't seem to bite, but it is causing a noticeable delay at boot time, when freezing processes prior to starting to read the image. The following patch adds invocation of try_to_freeze to the subloops that are used in the body of this function. With these additions, the time to freeze when starting to resume at boot time is virtually zero. I'm no expert on firewire, and so don't know that we shouldn't check the return value and jump back to the top of the loop or such like after being frozen, but I submit it for your consideration. Signed-off-by: Nigel Cunningham The delay until nodemgr freezes was up to 0.25s (plus time for node probes) in Linux 2.6.27 and older and up to 3.25s (plus ~) since Linux 2.6.28-rc1, hence much more noticeable. try_to_freeze() without any jump is correct. The surrounding code in the respective loops will catch whether another bus reset happens during the freeze and handle it.

Since the reporting is now done in the common search_binary_handler() function, an exec of a misc binary will result in two (or possibly multiple) exec events being reported, instead of just a single one, because the misc handler contains a recursive call to search_binary_handler. To add to the confusion, if PTRACE_O_TRACEEXEC is not active, the multiple SIGTRAP signals will in fact cause only a single ptrace intercept, as the signals are not queued. However, if PTRACE_O_TRACEEXEC is on, the debugger will actually see multiple ptrace intercepts (PTRACE_EVENT_EXEC). The test program included below demonstrates the problem. This change fixes the bug by calling tracehook_report_exec() only in the outermost search_binary_handler() call (bprm->recursion_depth == 0). The additional change to restore bprm->recursion_depth after each binfmt load_binary call is actually superfluous for this bug, since we test the value saved on entry to search_binary_handler(). But it keeps the use of of the depth count to its most obvious expected meaning. Depending on what binfmt handlers do in certain cases, there could have been false-positive tests for recursion limits before this change. /* Test program using PTRACE_O_TRACEEXEC.

Consider the following scenario: INITIAL STATE CPU0 has one napi_struct A on its poll_list CPU1 is calling netpoll_send_skb and needs to call poll_napi on the same napi_struct A that CPU0 has on its list CPU0 CPU1 net_rx_action poll_napi !list_empty (returns true) locks poll_lock for A poll_one_napi napi->poll netif_rx_complete __napi_complete (removes A from poll_list) list_entry(list->next) In the above scenario, net_rx_action assumes that the per-cpu poll_list is exclusive to that cpu. netpoll of course violates that, and because the netpoll path can dequeue from the poll list, its possible for CPU0 to detect a non-empty list at the top of the while loop in net_rx_action, but have it become empty by the time it calls list_entry. Since the poll_list isn't surrounded by any other structure, the returned data from that list_entry call in this situation is garbage, and any number of crashes can result based on what exactly that garbage is. Given that its not fasible for performance reasons to place exclusive locks arround each cpus poll list to provide that mutal exclusion, I think the best solution is modify the netpoll path in such a way that we continue to guarantee that the poll_list for a cpu is in fact exclusive to that cpu. To do this I've implemented the patch below. It adds an additional bit to the state field in the napi_struct. When executing napi->poll from the netpoll_path, this bit will be set. When a driver calls netif_rx_complete, if that bit is set, it will not remove the napi_struct from the poll_list. That work will be saved for the next iteration of net_rx_action. I've tested this and it seems to work well. About the biggest drawback I can see to it is the fact that it might result in an extra loop through net_rx_action in the event that the device is actually contended for (i.e. the netpoll path actually preforms all the needed work no the device, and the call to net_rx_action winds up doing nothing, except removing the napi_struct from the poll_list. However I think this is probably a small price to pay, given that the alternative is a crash. Signed-off-by: Neil Horman Signed-off-by: David S.

After this patch, percpu_counter_sum_and_set() has gone, and percpu_counter_sum() gets the old percpu_counter_sum_and_set() functionality. Problem is, as Eric points out, the old percpu_counter_sum_and_set() functionality was racy and wrong. It zeroes out counters on "other" cpus, without holding any locks which will prevent races agaist updates from those other CPUS. This patch reverts 1f7c14c62ce63805f9574664a6c6de3633d4a354. This means that percpu_counter_sum_and_set() still has the race, but percpu_counter_sum() does not. Note that this is not a simple revert - ext4 has since started using percpu_counter_sum() for its dirty_blocks counter as well. Note that this revert patch changes percpu_counter_sum() semantics. Before the patch, a call to percpu_counter_sum() will bring the counter's central counter mostly up-to-date, so a following percpu_counter_read() will return a close value. After this patch, a call to percpu_counter_sum() will leave the counter's central accumulator unaltered, so a subsequent call to percpu_counter_read() can now return a significantly inaccurate result. If there is any code in the tree which was introduced after e8ced39d5e8911c662d4d69a342b9d053eaaac4e was merged, and which depends upon the new percpu_counter_sum() semantics, that code will break.

While drain_all_pages() works on each cpu, lru_add_drain_all() only runs on the current cpu for architectures w/o CONFIG_NUMA. This let us run into the BUG_ON(!PageBuddy(page)) in __offline_isolated_pages() during memory hotplug stress test on s390. The page in question was still on the pcp list, because of a race with lru_add_drain_all() and drain_all_pages() on different cpus. Actually, Almost machine has CONFIG_UNEVICTABLE_LRU=y.

The current implementation of fbcon_exit() sets the fbcon workqueue function info->queue.func to NULL, but does not assure that there is no work pending when it does so. On occasion, depending on system timing, there will still be pending work in the queue when fbcon_exit() is called. This results in a null pointer deference when run_workqueue() tries to call the queue's work function.

Since commit 2f007e74bb85b9fc4eab28524052161703300f1a, do_pages_stat() gets the page address from user-space and puts the corresponding status back while holding the mmap_sem for read. There is no need to hold mmap_sem there while some page-faults may occur. This patch adds a temporary address and status buffer so as to only hold mmap_sem while working on these kernel buffers.

The MN10300 on-chip serial port uses three interrupts to manage its serial ports: (1) A very high priority interrupt that drives virtual DMA for Rx. (2) A very high priority interrupt that drives virtual DMA for Tx. (3) A normal priority virtual interrupt that does the normal UART interrupt stuff and is shared between Rx and Tx. mn10300_serial_stop_tx() only disables the high priority Tx interrupt. It doesn't also disable the normal priority one because it is shared with Rx. However, the high priority interrupt may interrupt local_irq_disabled() sections, and so may have queued up a low priority virtual interrupt whilst the UART driver is asking for the Tx interrupt to be disabled. The result of this can be an oops when we try to process the interrupt in mn10300_serial_transmit_interrupt() as port->uart.info and port->uart.info->tty may have gone away. To deal with this, if either of those pointers is NULL, we make sure the high-priority Tx interrupt is disabled and discard the interrupt. The low priority interrupt is disabled by the mn10300_serial_pic irq_chip table.

Bad bad bug, good good find. The i_mmap_writable count must be incremented for VM_SHARED (just as i_writecount is for VM_DENYWRITE, but while holding the i_mmap_lock) when dup_mmap() copies the vma for fork: it has its own more optimal version of __vma_link_file(), and I missed this out. So the count was later going down to 0 (dangerous) when one end unmapped, then wrapping negative (inefficient) when the other end unmapped. The only impact on x86 would have been that setting a mandatory lock on a file which has at some time been opened O_RDWR and mapped MAP_SHARED (but not necessarily PROT_WRITE) across a fork, might fail with -EAGAIN when it should succeed, or succeed when it should fail. But those architectures which rely on flush_dcache_page() to flush userspace modifications back into the page before the kernel reads it, may in some cases have skipped the flush after such a fork - though any repetitive test will soon wrap the count negative, in which case it will flush_dcache_page() unnecessarily.

Char 0x7c is mapped to U+00a5 which is the Yen sign and wrong. The right mapping is U+00a6 (broken bar). Furthermore, a mapping for U+00b4 (a widely used character) is missing even though easily possible. The patch fixes these, as well as it provides a few other useful mappings. The changes are as follows: 0x0f (enhancement) enables a sort of currency symbol 0x27 (bug) enables a sort of acute accent which is a widely used character 0x44 (enhancement) enables a sort of icelandic capital letter eth 0x7c (major bug) corrects mapping 0xeb (enhancement) enables a sort of icelandic small letter eth 0xee (enhancement) enables a sort of math 'element of' Signed-off-by: Ingo Brueckl Acked-by: H.

This seems to be meant as a kind of 'emergency fallback' for fonts without unicode mapping which otherwise would display nothing readable on the screen. At the moment it affects all chars for which no substitution character is defined. In particular this means that for all chars (>= 128) where there is no iso88591-1/unicode character (e.g. control character area) you'll get the very strange 1:1 mapping of the (cp437) graphics card glyphs. I'm pretty sure that the 1:1 mapping should only affect strict ASCII code characters, i.e. chars < 128. The patch limits the mapping as it probably was meant anyway.

Currently rebind_subsystems checks for the top cgroup's child list being empty in order to rebind subsystems into or out of a hierarchy - this can result in the set of subsystems bound to a hierarchy being removed-but-not-freed cgroup. The simplest fix for this is to forbid remounts that change the set of subsystems on a hierarchy that has removed-but-not-freed cgroups. This bug can be reproduced via: mkdir /mnt/cg mount -t cgroup -o ns,freezer cgroup /mnt/cg mkdir /mnt/cg/foo sleep 1h < /mnt/cg/foo & rmdir /mnt/cg/foo mount -t cgroup -o remount,ns,devices,freezer cgroup /mnt/cg kill $!

That changed the code ordering. I think this bug is triggered by having reserved areas for a node which are spanned by another node's contents. In the mark_reserved_regions_for_nid() code, we attempt to reserve the area for a node before we have allocated the NODE_DATA() for that nid. We do this since I reordered that loop. I suck. This is causing crashes at bootup on some systems, as reported by Jon Tollefson. This may only present on some systems that have 16GB pages reserved. But, it can probably happen on any system that is trying to reserve large swaths of memory that happen to span other nodes' contents. This commit ensures that we do not touch bootmem for any node which has not been initialized, and also removes a compile warning about an unused variable.

The problem is that after a kexec, the MSIC hardware still points into the middle of the old ring buffer. We set up the ring buffer during reboot, but not the offset into it. On older kernels, this would cause a storm of thousands of spurious interrupts after a kexec, which would most of the time get dropped silently. With the new code, we time out on each interrupt, waiting for it to become valid. If more interrupts come in that we time out on, this goes on indefinitely, which eventually leads to a hard crash. The solution in this commit is to read the current offset from the MSIC when reinitializing it. This now works correctly, as expected.

This inconsistency may lead to problems in the message parsing in userspace (if the message contains the CTA_NAT_SEQ_* attributes, of course). This patch breaks backward compatibility, however, the only known client of this code is libnetfilter_conntrack which indeed crashes because it assumes the existence of CTA_NAT_SEQ_UNSPEC to do the parsing.
