When the aic94xx driver creates ascbs, each ascb is initialized with a timeout timer. If there are any ascbs left over when the driver is being torn down, these timers need to be deleted. In particular, we seem to hit this case when ascbs are issued yet never end up on the done list. Right now there's a sequencer bug that results in this happening every so often. CONTROL PHY commands are typically sent when things are really messed up with the sequencer; however, any other leftover ascb should produce loud warnings. Signed-off-by:

This patch implements a REQ_DEVICE_RESET handler for the aic94xx driver. Like the earlier REQ_TASK_ABORT patch, this patch defers the device reset to the Scsi_Host's workqueue, which has the added benefit of ensuring that the device reset does not happen at the same time that the abort tmfs are being processed. After the phy reset, the busted drive should go away and be re-detected later, which is indeed what I've seen on both a x260 and a x206m. Signed-off-by:

Resetting the adapter causes the ServeRAID driver to exceed the max time allowed by the softlock watchdog. Resetting the hardware can easily require 30 or more seconds. To avoid the "BUG: soft lockup detected on CPU#0!" result, this patch adds a touch_nmi_watchdog() to the driver's MDELAY macro.

I wanted to add some BUG checks to scsi_prep_fn to make sure no one sends us a non-sg command, but this function is a horrible mess. So I decided to detangle the function and document what the valid cases are. While doing that I found that REQ_TYPE_SPECIAL commands aren't used by the SCSI layer anymore and we can get rid of the code handling them. The new structure of scsi_prep_fn is: (1) check if we're allowed to send this command (2) big switch on cmd_type. For the two valid types call into a function to set the command up, else error (3) code to handle error cases Because FS and BLOCK_PC commands are handled entirely separate after the patch this introduces a tiny amount of code duplication. This improves readabiulity though and will help to avoid the bidi command overhead for FS commands so it's a good thing. I've tested this on both sata and mptsas. Signed-off-by: -

scsi_send_eh_cmnd is the last user of non-sg commands currently. This patch switches it to a one-element SG list. Also updates the kerneldoc comment for scsi_send_eh_cmnd to reflect reality while we're at it. Test on my mptsas card, but this should get testing with as many drivers as possible. Signed-off-by:

This patch straightens out the code that distinguishes the various escb opcodes in escb_tasklet_complete so that they can be handled correctly. It also provides all the necessary code to create a workqueue item that tells libsas to abort a sas_task. Signed-off-by:

This patch adds an external function, sas_abort_task, to enable LLDDs to abort sas_tasks. It also adds a work_struct so that the actual work of aborting a task can be shifted from tasklet context (in the LLDD) onto the scsi_host's workqueue. Signed-off-by:

This patch adds an EH done queue to sas_ha, converts the error handling strategy function and the sas_scsi_task_done functions in libsas to use the scsi_eh_* commands for error'd commands, and adds checks for the INITIATOR_ABORTED flag so that we do the right thing if a sas_task has been aborted by the initiator.

If a drive reports that no media is present, there's no point in continuing to ask it about media status. This patch (as696) cuts the TUR polling short as soon as the drive reports no media instead of going a full 3 iterations. Signed-off-by:

Since it often takes around 20-30 seconds to scan a scsi bus, it's highly advantageous to do this in parallel with other things. The bulk of this patch is ensuring that devices don't change numbering, and that all devices are discovered prior to trying to start init. For those who build SCSI as modules, there's a new scsi_wait_scan module that will ensure all bus scans are finished. This patch only handles drivers which call scsi_scan_host. Fibre Channel, SAS, SATA, USB and Firewire all need additional work. Signed-off-by:

- fix: toshoboe_invalid_dev() was recently removed, but not all callers were updated, causing the obvious linker error. Remove caller, because the check (like the one removed) isn't used. - fix: propagate request_irq() return value - cleanup: remove void* casts - cleanup: remove impossible ASSERTs Signed-off-by:
