This was done by introduction of the pxa2xx_udc_mach_info member "gpio_pullup" which, if initialized, is now used in (almost) all places where udc_command used to be called.

It doesn't keep track of which interface (control or data) the sysfs attributes get registered for, and as a result, during disconnect it will sometimes attempt to remove the attributes from the wrong interface. The left-over attributes can cause a crash later on, particularly if the driver module has been unloaded.

Because the close function sends the 'abort' command, a parameter is added that allows the caller of garmin_write_bulk to specify, if the 'ack' should be propagated to the serial link or dimissed. This fixes the problem with gpsbabel, it has sent several packets that were acknowledged before they were sent to the GPS and GpsBabel closed the device - thus effectively cancelled all outstanding requests in the queue. - removed the APP_RESP_SEEN and APP_REQ_SEEN flags and changed them into counters. It evades USB reset of the gps on every device close.

The first problem, which apparently has been around for a while although nobody noticed it, shows up when an aborted command is still pending when a disconnect occurs. The SCSI error-handler will continue to wait in command_abort() until the us->notify completion is signalled. Thus quiesce_and_remove_host() needs to signal it. The second problem was introduced recently along with autosuspend support. Since usb_stor_scan_thread() now calls usb_autopm_put_interface() before exiting, we can't simply leave the scanning thread running after a disconnect; we must wait until the thread exits. This is solved by adding a new struct completion to the private data structure. Fortuitously, it allows the removal of the rather clunky mechanism used in the past to insure that all threads have finished before the module is unloaded.

Ok, lets kill the message. As Alois Nešpor also saw, that's fixed up by Yenta, so PCI does not have to warn about it. PCI could still warn about it if is_cardbus is 0 in that instance of pci_scan_bridge(), but so far I have not seen a report where this would have been the case so I think we can spare the kernel of that check (removes ~300 lines of asm) unless debugging is done. History: The whole check was added in the days before we had the fixup for this in Yenta and pci=assign-busses was the only way to get CardBus cards detected on many (not all) of the machines which give this warning. In theory, there could be cases when this warning would be triggered and it's not cardbus, then the warning should still apply, but I think this should only be the case when working on a completely broken PCI setup, but one may have already enabled the debug code in drivers/pci and the patched check would then trigger. I do not sign this off yet because it's completely untested so far, but everyone is free to test it (with the #ifdef DEBUG replaced by #if 1 and pr_debug( changed to printk(. We may also dump the whole check (remove everything within the #ifdef from the source) if that's perferred. On Alois Nešpor's machine this would then (only when debugging) this message: "PCI: Bus #0b (-#0e) is partially hidden behind transparent bridge #0a (-#0b)" "partially" should be in the message on his machine because #0b of #0b-#0e is reachable behind #0a-#0b, but not #0c-#0e. But that differentiation is now moot anyway because the fixup in Yenta takes care of it as far as I could see so far, which means that unless somebody is debugging a totally broken PCI setup, this message is not needed anymore, not even for debugging PCI. Ok, here the patch with the following changes: * Refined to say that the bus is only partially hidden when the parent bus numbers are not totally way off (outside of) the child bus range * remove the reference to pci=assign-busses and the plea to report it We could add a pure source code-only comment to keep a reference to pci=assign-busses the in case when this is triggered by someone who is debugging the cause of this message and looking the way to solve it.

This is followed by a number of errors and speed reduction steps on the affected ports. There are two bugs in pata_pdc2027x's PLL detection code: 1. The PLL counter's start value is read before the chip is put in "test mode". Outside of test mode the counter is halted, and on the PowerMac the counter is zero because the chip hasn't been initialised by its BIOS. The fix is to move the read of the start value to after test mode is started, but before the mdelay() in test mode. This also improves the precision of the PLL detection. 2. The code to compute the number of PLL decrements during the mdelay() in test mode fails to consider that the PLL counter only is 30 bits wide. If there is a wraparound, it will compute an incorrect and much too large value. On the PowerMac, the start count is zero, the end count is a large 30-bit value, so wraparound occurs and an out of bounds PLL clock is detected. The fix is to mask the (start - end) computation to 30 bits. While debugging this I also noticed that pdc_read_counter() reads the two halves of the 30-bit PLL counter as 16-bit values, and then combines them as if the halves only are 15 bits wide. To avoid confusion, the halves should be read as 15-bit values. This patch implements all three changes. It fixes the PLL detection failure on my PowerMac, and doesn't cause any regressions on an x86 with an identical card.

This allows the rq clock to work around TSC-stops-in-C2, TSC-gets-corrupted-in-C3 type of problems. ( Besides the scheduler's statistics this also benefits blktrace and printk-timestamps as well. ) Furthermore, the precise before-C2/C3-sleep and after-C2/C3-wakeup callbacks allow the scheduler to get out the most of the period where the CPU has a reliable TSC.

However, there was a minor difference between the code in lgh06xf and dvb-pll, which caused a regression in b2c2-flexcop devices using the LG-H06xF NIM. dvb-pll will probe for the presence of an i2c pll chip by performing a single byte read, the lgh06xf driver did not do this. Unfortunately, the code in flexcop-i2c.c does not currently support 1 byte or 0 byte reads as a probe. Such probes with the current code will always fail. In order to work around this problem, and restore proper functionality of the Airstar HD5000 device, this hack was created to make the probe appear to succeed. The single byte read in dvb_pll_attach is the only place where such a probe would ever occur, so this change is safe, and will not affect any other devices. Of course, if one knew how to actually perform the read operation, it would be better to go that route. In the meantime, however, we must apply this workaround, in order to prevent the regression that causes tuning to fail on the Airstar HD5000 ATSC device. Thanks to Jarod Wilson, who had originally reported this regression, and to Geoffrey Hausheer, whose original workaround patch led us to find the actual cause of the problem.

ACPI 2.0 adds an XSDT with 32-bit physical addresses. An ACPI 2.0 aware OS is supposed to use the XSDT (when present) instead of the RSDT. However, several systems have failed because the XSDT contains NULL entries -- while it is missing pointers to needed tables, such as SSDTs. When we find an XSDT with NULL entries, discard it and use the ACPI 1.0 RSDT instead. http://bugzilla.kernel.org/show_bug.cgi?id=8630 Signed-off-by: Zhao Yakui Signed-off-by: Len Brown --- drivers/acpi/tables/tbutils.c | 71 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 71 insertions(+) (limited to 'drivers') diff --git a/drivers/acpi/tables/tbutils.c b/drivers/acpi/tables/tbutils.c index 1da64b4518c..8cc9492ffbf 100644 --- a/drivers/acpi/tables/tbutils.c +++ b/drivers/acpi/tables/tbutils.c @@ -51,6 +51,65 @@ ACPI_MODULE_NAME("tbutils") static acpi_physical_address acpi_tb_get_root_table_entry(u8 * table_entry, acpi_native_uint table_entry_size); +/******************************************************************************* + * + * FUNCTION: acpi_tb_check_xsdt + * + * PARAMETERS: address - Pointer to the XSDT + * + * RETURN: status + * AE_OK - XSDT is okay + * AE_NO_MEMORY - can't map XSDT + * AE_INVALID_TABLE_LENGTH - invalid table length + * AE_NULL_ENTRY - XSDT has NULL entry + * + * DESCRIPTION: validate XSDT +******************************************************************************/ + +static acpi_status +acpi_tb_check_xsdt(acpi_physical_address address) +{ + struct acpi_table_header *table; + u32 length; + u64 xsdt_entry_address; + u8 *table_entry; + u32 table_count; + int i; + + table = acpi_os_map_memory(address, sizeof(struct acpi_table_header)); + if (!table) + return AE_NO_MEMORY; + + length = table->length; + acpi_os_unmap_memory(table, sizeof(struct acpi_table_header)); + if (length < sizeof(struct acpi_table_header)) + return AE_INVALID_TABLE_LENGTH; + + table = acpi_os_map_memory(address, length); + if (!table) + return AE_NO_MEMORY; + + /* Calculate the number of tables described in XSDT */ + table_count = + (u32) ((table->length - + sizeof(struct acpi_table_header)) / sizeof(u64)); + table_entry = + ACPI_CAST_PTR(u8, table) + sizeof(struct acpi_table_header); + for (i = 0; i < table_count; i++) { + ACPI_MOVE_64_TO_64(&xsdt_entry_address, table_entry); + if (!xsdt_entry_address) { + /* XSDT has NULL entry */ + break; + } + table_entry += sizeof(u64); + } + acpi_os_unmap_memory(table, length); + + if (i < table_count) + return AE_NULL_ENTRY; + else + return AE_OK; +} /******************************************************************************* * @@ -341,6 +400,7 @@ acpi_tb_parse_root_table(acpi_physical_address rsdp_address, u8 flags) u32 table_count; struct acpi_table_header *table; acpi_physical_address address; + acpi_physical_address rsdt_address; u32 length; u8 *table_entry; acpi_status status; @@ -369,6 +429,8 @@ acpi_tb_parse_root_table(acpi_physical_address rsdp_address, u8 flags) */ address = (acpi_physical_address) rsdp->xsdt_physical_address; table_entry_size = sizeof(u64); + rsdt_address = (acpi_physical_address) + rsdp->rsdt_physical_address; } else { /* Root table is an RSDT (32-bit physical addresses) */ @@ -382,6 +444,15 @@ acpi_tb_parse_root_table(acpi_physical_address rsdp_address, u8 flags) */ acpi_os_unmap_memory(rsdp, sizeof(struct acpi_table_rsdp)); + if (table_entry_size == sizeof(u64)) { + if (acpi_tb_check_xsdt(address) == AE_NULL_ENTRY) { + /* XSDT has NULL entry, RSDT is used */ + address = rsdt_address; + table_entry_size = sizeof(u32); + ACPI_WARNING((AE_INFO, "BIOS XSDT has NULL entry," + "using RSDT")); + } + } /* Map the RSDT/XSDT table header to get the full table length */ table = acpi_os_map_memory(address, sizeof(struct acpi_table_header)); -- cgit v1.2.3 From 6e106b0d97e79f1abb60cc49a53af760950c3384 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Fri, 24 Aug 2007 15:35:15 -0700 Subject: DM_MULTIPATH_RDAC: "scsi_normalize_sense" undefined DM_MULTIPATH_RDAC uses SCSI API(s) and is for a SCSI device, so add SCSI to its depends on to prevent build errors.

In this case, all the relevant drivers are platform drivers, and this patch either (a) Changes the driver name, if no in-tree code would break; this is simpler and thus preferable in the long term. (b) Adds MODULE_ALIAS directives, when in-tree platforms declare devices using the current driver name; less desirable. Most systems will link SPI controller drivers statically, but there's no point in being needlessly broken.

The IOC3 driver's UART detection bits used to rely on the the firmware setting the UART pre-divider in a way that's apropriate for the 8250 driver which doesn't currently program this register.

While at it, also program the UART to RS-232 PIO mode; it the UART might have been in mac-serial and/or DMA mode though that hasn't actually been observed in practice.

In qeth_remove_device() an interruptible wait operation is used to wait until a qeth recovery thread is finished. If a user really interrupts the ungroup operation of a qeth device while a recovery is running, cio and qeth are out of sync (device already removed from cio, but kept in qeth). A following module unload of qeth results in a kernel OOPS here. Solution: Do not allow interruption of ungroup operation to guarantee finishing of a potentially running qeth recovery thread.

On x86[-64], trying to register this clocksource results in potentially multiple hpet-based clocksources being registered, and if the ia64 one is chosen on x86_64 some users have experienced hangs.

Previously, in the absence of PEC (rarely used!) it would NAK the "length" byte: S addr Rd [A] [length] NA That prevents the subsequent data bytes from being read: S addr Rd [A] [length] { A [data] }* NA The primary fix just reorders two code blocks, so the length used in the "should I NAK now?" check incorporates the data which it just read from the slave device. However, that move also highlighted other fault handling glitches. This fixes those by abstracting the RX path ack/nak logic, so it can be used in more than one location. Also, a few CodingStyle issues were also resolved.

A hardware bug was revealed after a recent PCI MSI patch was made to always disable legacy INTX when enabling MSI. The 5714/5780 chips will not generate MSI when INTX is disabled, causing MSI failure messages to be reported, and another patch was made to workaround the problem by disabling MSI on ServerWorks HT1000 bridge chips commonly found with the 5714. We workaround this chip bug by enabling INTX after we enable MSI and after we resume from suspend. Update version to 3.81. This problem was discovered by David Miller.

The problem happens because, - In Cell architecture, interrupts may arrive at an interrupt controller, even if they are masked by the setting on registers of devices. It happens when interrupt packets are sent just before the interrupts are masked. - spidernet interrupt handler compares interrupt reasons with interrupt masks, so when such interrupts occurs, spidernet interrupt handler returns IRQ_NONE. - When all of interrupt handler return IRQ_NONE, linux kernel disables the IRQ and it no longer delivers interrupts to the interrupt handlers. spidernet doesn't work after above sequence, because it can't receive interrupts. This patch changes spidernet interrupt handler that it compares interrupt reason with SPIDER_NET_INTX_MASK_VALUE.

This fix modifies the shutdown of work queues and prevents periodic work from being requeued during shutdown. With this patch, no more crashes on reboot were observed by the original reporter. I do not get that particular failure on my system; however, when running a large number of ifdown/ifup sequences, my system would kernel panic with the 'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT' errors. With this patch, no more of the first type of failure occur, and incidence of the second type is greatly reduced.

CONFIG_THINKPAD_ACPI_INPUT_ENABLED was added to try to fix an issue that is now moot with the addition of the netlink ACPI event report interface to the ACPI core. Now that ACPI core can send events over netlink, we can use a different strategy to keep backwards compatibility with older userspace, without the need for the CONFIG_THINKPAD_ACPI_INPUT_ENABLED games. And it arrived before CONFIG_THINKPAD_ACPI_INPUT_ENABLED made it to a stable mainline kernel, even, which is Good. This patch is in sync with some changes to thinkpad-acpi backports, that will keep things sane for userspace across different combinations of kernel versions, thinkpad-acpi backports (or the lack thereof), and userspace capabilities: Unless a module parameter is used, thinkpad-acpi will now behave in such a way that it will work well (by default) with userspace that still uses only the old ACPI procfs event interface and doesn't care for thinkpad-acpi input devices. It will also always work well with userspace that has been updated to use both the thinkpad-acpi input devices, and ACPI core netlink event interface, regardless of any module parameter. The module parameter was added to allow thinkpad-acpi to work with userspace that has been partially updated to use thinkpad-acpi input devices, but not the new ACPI core netlink event interface. To use this mode of hot key reporting, one has to specify the hotkey_report_mode=2 module parameter. The thinkpad-acpi driver exports the value of hotkey_report_mode through sysfs, as well. thinkpad-acpi backports to older kernels, that do not support the new ACPI core netlink interface, have code to allow userspace to switch hotkey_report_mode at runtime through sysfs. This capability will not be provided in mainline thinkpad-acpi as it is not needed there. Signed-off-by: Henrique de Moraes Holschuh Cc: Michael S.

But this conflicts with Linux native graphics drivers, and can cause all sorts of issues, including hanging the system. http://bugzilla.kernel.org/show_bug.cgi?id=6001 Here we change the Linux default to evaluate _DOS=0, which tells the BIOS to simply send us a hotkey event and not touch the graphics hardware. The acpi video driver sends the display switch hotkey event up through the intput layer, and X can interpret that and use its native graphics driver to switch the display. For the case where Linux has no native graphics driver running, or the graphics driver doesn't know how to switch video and the BIOS (safely) does, the previous behaviour can be restored with: # echo 1 > /proc/acpi/video/*/DOS Signed-off-by: Zhang Rui Signed-off-by: Len Brown --- drivers/acpi/video.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers') diff --git a/drivers/acpi/video.c b/drivers/acpi/video.c index 3c9bb85a6a9..6cb3e7b1214 100644 --- a/drivers/acpi/video.c +++ b/drivers/acpi/video.c @@ -1754,7 +1754,7 @@ static int acpi_video_bus_put_devices(struct acpi_video_bus *video) static int acpi_video_bus_start_devices(struct acpi_video_bus *video) { - return acpi_video_bus_DOS(video, 1, 0); + return acpi_video_bus_DOS(video, 0, 0); } static int acpi_video_bus_stop_devices(struct acpi_video_bus *video) -- cgit v1.2.3 From 7f10cc4e838c2b2d7272031954c56c407569d497 Mon Sep 17 00:00:00 2001 From: Maik Broemme Date: Fri, 14 Sep 2007 22:12:34 +0200 Subject: ACPI: video: remove dmesg spam i am actually heavily using the ACPI video extension for my Thinkpad X61 Tablet.

If the mapped size of the vma (vm_area_struct) is very large, mspec allocates a large vma_data structure with vmalloc(). But such a vma can be shrunk by an munmap(2). The current driver uses the current size of each vma to deduce whether its vma_data structure was allocated by kmalloc() or vmalloc(). So if the vma was shrunk it appears to have been allocated by kmalloc(), and mspec attempts to free it with kfree(). This results in a panic. This patch avoids the panic (by preserving the type of the allocation) and also makes mspec work correctly as the vma is split into pieces by the munmap(2)'s. All vma's derived from such a split vma share the same vma_data structure that represents all the pages mapped into this set of vma's. The mpec driver must be made capable of using the right portion of the structure for each member vma. In other words, it must index into the array of page addresses using the portion of the array that represents the current vma. This is enabled by storing the vma group's vm_start in the vma_data structure. The shared vma_data's are not protected by mm->mmap_sem in the fork() case so the reference count is left as atomic_t.

It also gets rid of skb2 we only need to preserve the original skb for congestion notification, which is only applicable for ppp_async and ppp_sync. The other semantic change made here is the removal of socket accounting for data tranmitted out of pppol2tp_xmit. The original code leaked any existing socket skb accounting. We could fix this by dropping the original skb owner. However, this is undesirable as the packet has not physically left the host yet. In fact, all other tunnels in the kernel do not account skb's passing through to their own socket. In partciular, ESP over UDP does not do so and it is the closest tunnel type to PPPoL2TP. So this patch simply removes the socket accounting in pppol2tp_xmit. The accounting still applies to control packets of course. I've also added a reminder that the outgoing checksum here doesn't work. I suppose existing deployments don't actually enable checksums. Signed-off-by: Herbert Xu Signed-off-by: David S.

The problem is that the first test it does is a cable integrity test for wide transfers and if this fails, it turns the wide bit off. The problem is that the next set of tests it does turns wide back on again, with the result that it runs through the entirety of DV with a known bad setting and then hangs the system. The attached patch fixes the problem by physically nailing the wide setting to what it deduces it should be for the whole of Domain Validation.

It took me some time to realize that especially the VAIO BIOSes (both Andrews jinxed UP and my elfstruck SMP one) show this effect. I'm quite sure that other bug reports against suspend/resume about turning the system into a brick have the same root cause. After fishing in the dark for quite some time, I realized that removing the ACPI processor module before suspend (this removes the lower C-state functionality) made the problem disappear. Interestingly enough the propability of having a bricked box is influenced by various factors (interrupts, size of the ram image, ...). Even adding a bunch of printks in the wrong places made the problem go away. The previous periodic tick implementation simply pampered over the problem, which explains why the dyntick / clockevents changes made this more prominent. We avoid complex functionality during the boot process and we have to do the same during suspend/resume. It is a similar scenario and equaly fragile. Add suspend / resume functions to the ACPI processor code and disable the lower idle C-states across suspend/resume. Fall back to the default idle implementation (halt) instead.

We also need to handle prefetch marking properly for S/G segments, or else the HCA may end up processing S/G segments that are not fully written and end up sending the wrong data. This can actually cause data corruption in practice, especially on systems with relatively slow CPUs (where the HCA is more likely to prefetch while the CPU is in the middle of writing a work request into memory). We write S/G segments in reverse order into the WQE, in order to guarantee that the first dword of all cachelines containing S/G segments is written last (overwriting the headroom invalidation pattern). The entire cacheline will thus contain valid data when the invalidation pattern is overwritten.

However the process of determining whether more read requests are pending requires locking the stripe (to block add_stripe_bio from updating dev->toead). ops_complete_biofill can run in tasklet context, so rather than upgrading all the stripe locks from spin_lock to spin_lock_bh this patch just unconditionally reschedules handle_stripe after completing the read request. 2/ ops_complete_biofill needlessly qualified processing R5_Wantfill with dev->toread. The result being that the 'biofill' pending bit is cleared before handling the pending read-completions on dev->read. R5_Wantfill can be unconditionally handled because the 'biofill' pending bit prevents new R5_Wantfill requests from being seen by ops_run_biofill and ops_complete_biofill.

If IRQ pending is cleared after reading IRQ status, there's possibility of lost IRQ. If IRQ pending is cleared before reading IRQ status, spurious IRQs will occur. sata_sil24 till now cleared IRQ pending after reading IRQ status thus losing IRQs on machines where PCIX_IRQ_WOC was used.

Depending on how your kernel is linked and other random factors, you can end up with this driver matched against any other PCI device in your system, possibly crashing at boot. Thanks to Heikki for tracking this down with me, the bug have been there for some time, though it rarely hurts due to luck. In this case, the switch from .22 to .23-rc9 is causing it to show up due to differences in the resulting layout of .data I suppose.
