2008-12-10oprofile: fix lost sample counterRobert Richter
The number of lost samples could be greater than the number of received samples. This patches fixes this. The implementation introduces return values for add_sample() and add_code(). Signed-off-by: Robert Richter <robert.richter@amd.com>
2008-12-10oprofile: remove nr_available_slots()Robert Richter
This function is no longer available after the port to the new ring buffer. Its removal can lead to incomplete sampling sequences since IBS samples and backtraces are transfered in multiple samples. Due to a full buffer, samples could be lost any time. The userspace daemon has to live with such incomplete sampling sequences as long as the data within one sample is consistent. This will be fixed by changing the internal buffer data there all data of one IBS sample or a backtrace is packed in a single ring buffer entry. This is possible since the new ring buffer supports variable data size. Signed-off-by: Robert Richter <robert.richter@amd.com>
2008-12-10oprofile: port to the new ring_bufferRobert Richter
This patch replaces the current oprofile cpu buffer implementation with the ring buffer provided by the tracing framework. The motivation here is to leave the pain of implementing ring buffers to others. Oh, no, there are more advantages. Main reason is the support of different sample sizes that could be stored in the buffer. Use cases for this are IBS and Cell spu profiling. Using the new ring buffer ensures valid and complete samples and allows copying the cpu buffer stateless without knowing its content. Second it will use generic kernel API and also reduce code size. And hopefully, there are less bugs. Since the new tracing ring buffer implementation uses spin locks to protect the buffer during read/write access, it is difficult to use the buffer in an NMI handler. In this case, writing to the buffer by the NMI handler (x86) could occur also during critical sections when reading the buffer. To avoid this, there are 2 buffers for independent read and write access. Read access is in process context only, write access only in the NMI handler. If the read buffer runs empty, both buffers are swapped atomically. There is potentially a small window during swapping where the buffers are disabled and samples could be lost. Using 2 buffers is a little bit overhead, but the solution is clear and does not require changes in the ring buffer implementation. It can be changed to a single buffer solution when the ring buffer access is implemented as non-locking atomic code. The new buffer requires more size to store the same amount of samples because each sample includes an u32 header. Also, there is more code to execute for buffer access. Nonetheless, the buffer implementation is proven in the ftrace environment and worth to use also in oprofile. Patches that changes the internal IBS buffer usage will follow.

2008-12-01i82875p_edac: fix module removeJarkko Lavinen
Fix module removal bugs of i82875p_edac. 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. If kernel debugging options are not enabled, user may not notice anything going wrong. if debugging options are enabled and I do "rmmod i82875p_edac", I get: edac debug: edac_pci_workq_function() checking BUG: unable to handle kernel paging request at f882d16f ... call trace: [<f8834df3>] ? edac_mc_workq_function+0x55/0x7e [edac_core] [<c0233974>] ? run_workqueue+0xd7/0x1a5 [<c023392f>] ? run_workqueue+0x92/0x1a5 [<f8834d9e>] ? edac_mc_workq_function+0x0/0x7e [edac_core] [<c0233af9>] ? worker_thread+0xb7/0xc3 [<c0236a7b>] ? autoremove_wake_function+0x0/0x33 [<c0233a42>] ? worker_thread+0x0/0xc3 [<c0236809>] ? kthread+0x3b/0x61 [<c02367ce>] ? kthread+0x0/0x61 [<c0204587>] ? kernel_thread_helper+0x7/0x10 Fix for this is to get rid of needles variable i82875p_registered altogether and run i82875p_remove_one() *before* pci_unregister_driver(). 2. edac_mc_del_mc() uses mci after freeing mci edac_mc_del_mc() calls calls edac_remove_sysfs_mci_device(). 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.

2008-12-01i82875p_edac: fix overflow device resource setupJarkko Lavinen
When I do "modprobe i82875p_edac" on my Asus P4C800 MB on kernels 2.6.26 or later, the module load fails due to BAR 0 collision. On 2.6.25 the module loads just fine. The overflow device on the MB seems to be hidden and its resources are not allocated at normal PCI bus init. Log shows the missing resource problem: EDAC DEBUG: i82875p_probe1() PCI: 0000:00:06.0 reg 10 32bit mmio: [fecf0000, fecf0fff] pci 0000:00:06.0: device not available because of BAR 0 [0xfecf0000-0xfecf0fff] collisions EDAC i82875p: i82875p_setup_overfl_dev(): Failed to enable overflow device The patch below fixes this by calling pci_bus_assign_resources() after the overflow device is revealed and added to the bus.

2008-12-01fbdev: fix FB console blankingDmitry Baryshkov
The commit aef7db4bd5a3b6068dfa05919a3d685199eed116 fixed the problem with recursive locking in fb blanking code if blank is caused by user setting the /sys/class/graphics/fb*/blank. 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.

Tecra M4 sometimes forget what it is and reports bogus data via DMI which makes the machine evade broken suspend matching and thus fail suspend/resume. This patch updates piix_broken_suspend() such that it can match such case. As the borked DMI data is a bit generic, matching many entries to make the match more specific is necessary. As the usual DMI matching is limited to four entries, this patch uses hard coded manual matching. This is reported by Alexandru Romanescu.

2008-12-01IB/mlx4: Fix MTT leakage in resize CQJack Morgenstein
When resizing a CQ, MTTs associated with the old CQE buffer were not freed. 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 <https://bugs.openfabrics.org/show_bug.cgi?id=1416>.

2008-12-01IB/ehca: Fix problem with generated flush work completionsStefan Roscher
This fix enables ehca device driver to generate flush work completions even if the application doesn't request completions for all work requests. The current implementation of ehca will generate flush work completions for the wrong work requests if an application uses non signaled work completions.

2008-12-01IB/ehca: Change misleading error message on memory hotplugJoachim Fenkes
The error message printed when the eHCA driver prevents memory hotplug is misleading -- the user might think that hot-removing the lhca, hotplugging memory, then hot-adding the lhca again will work, but it actually doesn't.

2008-12-01Add kref to fake tty used by USB consoleKevin Hao
We alloc a fake tty in usb serial console setup function. we should init the tty's kref otherwise we will face WARN_ON after following invoke of tty_port_tty_set --> tty_kref_get.
