block: Change the return type of blk_mq_map_queues() into void

2022-08-22T16:07:53Z

Since blk_mq_map_queues() and the .map_queues() callbacks always return 0, change their return type into void. Most callers ignore the returned value anyway.

scsi: smartpqi: Add ctrl ready timeout module parameter

2022-07-14T03:42:04Z

Allow user to override the default driver timeout for controller ready. There are some rare configurations which require the driver to wait longer than the normal 3 minutes for the controller to complete its bootup sequence and be ready to accept commands from the driver. The module parameter is: ctrl_ready_timeout= { 0 | 30-1800 } and specifies the timeout in seconds for the driver to wait for controller ready. The valid range is 0 or 30-1800. The default value is 0, which causes the driver to use a timeout of 180 seconds (3 minutes).

scsi: smartpqi: Add module param to disable managed ints

2022-07-14T03:42:04Z

Allow SMP affinity to be changeable by disabling managed interrupts. On distributions where the driver is enabled for multi-queue support the driver utilizes kernel managed interrupts, which automatically distributes interrupts to all available CPUs and assigns SMP affinity. On most distributions, the affinity can not be changed by the user. This change will allow managed interrupts to be disabled by the user via a module parameter while still allowing multi-queue support to function properly. Use the module parameter disable_managed_interrupts=1 Link: https://lore.kernel.org/r/165730606638.177165.12846020942931640329.stgit@brunhilda Reviewed-by: Scott Benesh Reviewed-by: Scott Teel Reviewed-by: Kevin Barnett Signed-off-by: Mike McGowen Signed-off-by: Don Brace Signed-off-by: Martin K.

scsi: smartpqi: Fix RAID map race condition

2022-07-14T03:42:04Z

Correct a rare stale RAID map access when performing AIO during a RAID configuration change. A race condition in the driver could cause it to access a stale RAID map when a logical volume is reconfigured. Modify the driver logic to invalidate a RAID map very early when a RAID configuration change is detected and only switch to a new RAID map after the driver detects that the RAID map has changed.

scsi: smartpqi: Fix DMA direction for RAID requests

2022-07-14T03:42:04Z

Correct a SOP READ and WRITE DMA flags for some requests. This update corrects DMA direction issues with SCSI commands removed from the controller's internal lookup table. Currently, SCSI READ BLOCK LIMITS (0x5) was removed from the controller lookup table and exposed a DMA direction flag issue. SCSI READ BLOCK LIMITS was recently removed from our controller lookup table so the controller uses the respective IU flag field to set the DMA data direction. Since the DMA direction is incorrect the FW never completes the request causing a hang. Some SCSI commands which use SCSI READ BLOCK LIMITS * sg_map * mt -f /dev/stX status After updating controller firmware, users may notice their tape units failing. This patch resolves the issue. Also, the AIO path DMA direction is correct. The DMA direction flag is a day-one bug with no reported BZ.
