| * [SCSI] aic94xx: fix sequencer hang on error recoveryJames Bottomley2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The clear nexus I_T and clear nexus I_T_L functions in the aic94xx specify the SUSPEND_TX flag which causes the sequencer to be suspended until it receives a RESUME_TX. Unfortunately, nothing ever sends the resume, so the sequencer on the link is stopped forever, leading to eventual timeouts and I/O errors. Since clear nexus commands are only executed as part of error recovery, it's perfectly fine to keep the sequencer running on the link ... as soon as the recovery function is completed, we'll send it the commands to retry.

| * [SCSI] stex: stex_internal_copy should be called with sg_count in struct st_ccbFUJITA Tomonori2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stex_internal_copy copies an in-kernel buffer to a sg list by using scsi_kmap_atomic_sg. Some functions calls stex_internal_copy with sg_count in struct st_ccb, which is the value that dma_map_sg returned. However it might be shorter than the actual number of sg entries (if the IOMMU merged the sg entries). scsi_kmap_atomic_sg doesn't see sg->dma_length so stex_internal_copy should be called with the actual number of sg entries (i.e. scsi_sg_count), because if the sg entries were merged, stex_direct_copy wrongly think that the data length in the sg list is shorter than the actual length.

| * [SCSI] stex: stex_direct_copy shouldn't call dma_map_sgFUJITA Tomonori2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stex_direct_copy copies an in-kernel buffer to a sg list in order to spoof some SCSI commands. stex_direct_copy calls dma_map_sg and then stex_internal_copy with the value that dma_map_sg returned. It calls scsi_kmap_atomic_sg to copy data. scsi_kmap_atomic_sg doesn't see sg->dma_length so if dma_map_sg merges sg entries, stex_internal_copy gets the smaller number of sg entries than the acutual number, which means it wrongly think that the data length in the sg list is shorter than the actual length. stex_direct_copy shouldn't call dma_map_sg and it doesn't need since this code path doesn't involve dma transfers. This patch removes stex_direct_copy and simply calls stex_internal_copy with the actual number of sg entries.

| * [SCSI] libsas: fix error handlingJames Bottomley2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The libsas error handler has two fairly fatal bugs 1. scsi_sas_task_done calls scsi_eh_finish_cmd() too early. This happens if the task completes after it has been aborted but before the error handler starts up. Because scsi_eh_finish_cmd() decrements host_failed and adds the task to the done list, the error handler start check (host_failed == host_busy) never passes and the eh never starts. 2. The multiple task completion paths sas_scsi_clear_queue_... all simply delete the task from the error queue. This causes it to disappear into the ether, since a command must be placed on the done queue to be finished off by the error handler. This behaviour causes the HBA to hang on pending commands. Fix 1. by moving the SAS_TASK_STATE_ABORTED check to an exit clause at the top of the routine and calling ->scsi_done() unconditionally (it is a nop if the timer has fired). This keeps the task in the error handling queue until the eh starts. Fix 2. by making sure every task goes through task complete followed by scsi_eh_finish_cmd(). Tested this by firing resets across a disk running a hammer test (now it actually survives without hanging the system) Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver has been failing under heavy load with aic94xx: escb_tasklet_complete: REQ_TASK_ABORT, reason=0x6 aic94xx: escb_tasklet_complete: Can't find task (tc=4) to abort! The second message is because the driver fails to identify the task it's being asked to abort. On closer inpection, there's a thinko in the for each task loop over pending tasks in both the REQ_TASK_ABORT and REQ_DEVICE_RESET cases where it doesn't look at the task on the pending list but at the one on the ESCB (which is always NULL). Fix by looking at the right task. Also add a print for the case where the pending SCB doesn't have a task attached. Not sure if this will fix all the problems, but it's a definite first step.

* | PM: Introduce PM_EVENT_HIBERNATE callback stateRafael J. Wysocki2008-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the last step of hibernation in the "platform" mode (with the help of ACPI) we use the suspend code, including the devices' ->suspend() methods, to prepare the system for entering the ACPI S4 system sleep state. But at least for some devices the operations performed by the ->suspend() callback in that case must be different from its operations during regular suspend. For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and pass it to the device drivers' ->suspend() methods during the last phase of hibernation, so that they can distinguish this case and handle it as appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a special way and need to handle PM_EVENT_HIBERNATE in the same way. These changes are necessary to fix a hibernation regression related to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488). Signed-off-by: Rafael J.

* | libata: eliminate the home grown dma padding in favour ofJames Bottomley2008-02-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | that provided by the block layer ATA requires that all DMA transfers begin and end on word boundaries. Because of this, a large amount of machinery grew up in ide to adjust scatterlists on this basis. However, as of 2.5, the block layer has a dma_alignment variable which ensures both the beginning and length of a DMA transfer are aligned on the dma_alignment boundary. Although the block layer does adjust the beginning of the transfer to ensure this happens, it doesn't actually adjust the length, it merely makes sure that space is allocated for transfers beyond the declared length. The upshot of this is that scatterlists may be padded to any size between the actual length and the length adjusted to the dma_alignment safely knowing that memory is allocated in this region. Right at the moment, SCSI takes the default dma_aligment which is on a 512 byte boundary. Note that this aligment only applies to transfers coming in from user space. However, since all kernel allocations are automatically aligned on a minimum of 32 byte boundaries, it is safe to adjust them in this manner as well. tj: * Adjusting sg after padding is done in block layer. Make libata set queue alignment correctly for ATAPI devices and drop broken sg mangling from ata_sg_setup(). * Use request->raw_data_len for ATAPI transfer chunk size. * Killed qc->raw_nbytes. * Separated out killing qc->n_iter.

* | block: add request->raw_data_lenTejun Heo2008-02-19
|/ | | | | | | | | | | | | | | | | | | | | | | With padding and draining moved into it, block layer now may extend requests as directed by queue parameters, so now a request has two sizes - the original request size and the extended size which matches the size of area pointed to by bios and later by sgs. The latter size is what lower layers are primarily interested in when allocating, filling up DMA tables and setting up the controller. Both padding and draining extend the data area to accomodate controller characteristics. As any controller which speaks SCSI can handle underflows, feeding larger data area is safe. So, this patch makes the primary data length field, request->data_len, indicate the size of full data area and add a separate length field, request->raw_data_len, for the unmodified request size. The latter is used to report to higher layer (userland) and where the original request size should be fed to the controller or device.

* [SCSI] MegaRAID driver management char device moved to miscThomas Horsten2008-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | The MegaRAID driver's common management module (megaraid_mm.c) creates a char device used by the management tool "megarc" from LSI Logic (and possibly other management tools). In 2.6 with udev, this device doesn't get created because it is not registered in sysfs. I first fixed this by registering a class "megaraid_mm", but realized that this should probably be moved to misc devices, instead of taking up a char major. This is because only 1 device is used, even if there are multiple adapters - the minor is never used (the adapter info is in the ioctl block sent to the driver, not detected based on the minor number as one might think). So it is a complete waste to have an entire major taken by this. So it now uses a misc device which I named "megadev0" (the name that megarc expects), and has a dynamic minor (previoulsy a dynamic major was used). I have tested this on my own system with the megarc tool, and it works just as fine as before (only now the device gets created correctly by udev).

* [SCSI] advansys: fix overrun_buf aligned bugFUJITA Tomonori2008-02-11
| | | | | | | | | | | | | | | | | | | | | | struct asc_dvc_var needs overrun buffer to be placed on an 8 byte boundary. advansys defines struct asc_dvc_var: struct asc_dvc_var { ... uchar overrun_buf[ASC_OVERRUN_BSIZE] __aligned(8); The problem is that struct asc_dvc_var is placed on shost->hostdata. So if the hostdata is not on an 8 byte boundary, the advansys crashes. The hostdata is placed on a sizeof(unsigned long) boundary so the 8 byte boundary is not garanteed with x86_32. With 2.6.23 and 2.6.24, the hostdata is on an 8 byte boundary by chance, but with the current git, it's not. This patch removes overrun_buf static array and use kzalloc.
