2022-07-13scsi: smartpqi: Add ctrl ready timeout module parameterKevin Barnett
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).

2022-07-13scsi: smartpqi: Add module param to disable managed intsMike McGowen
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 <scott.benesh@microchip.com> Reviewed-by: Scott Teel <scott.teel@microchip.com> Reviewed-by: Kevin Barnett <kevin.barnett@microchip.com> Signed-off-by: Mike McGowen <Mike.McGowen@microchip.com> Signed-off-by: Don Brace <don.brace@microchip.com> Signed-off-by: Martin K.

2022-07-13scsi: smartpqi: Fix RAID map race conditionKevin Barnett
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.

2022-07-13scsi: smartpqi: Fix DMA direction for RAID requestsMahesh Rajashekhara
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.

Fail all outstanding requests after a PCI linkdown. Block access to device SCSI attributes during the following conditions: "Cable pull" is called PQI_CTRL_SURPRISE_REMOVAL. "PCIe Link Down" is called PQI_CTRL_GRACEFUL_REMOVAL. Block access to device SCSI attributes during and in rare instances when the controller goes offline. Either outstanding requests or the access of SCSI attributes post linkdown can lead to a hang. Post linkdown, driver does not fail the outstanding requests leading to long wait time before all the IOs eventually fail. Also access of the SCSI attributes by host applications can lead to a system hang.

2022-07-07scsi: sd: Rework asynchronous resume supportBart Van Assche
For some technologies, e.g. an ATA bus, resuming can take multiple seconds. Waiting for resume to finish can cause a very noticeable delay. Hence this commit that restores the behavior from before "scsi: core: pm: Rely on the device driver core for async power management" for most SCSI devices. This commit introduces a behavior change: if the START command fails, do not consider this as a SCSI disk resume failure.

The SCSI core code does not currently support reserved commands. As such, requests which time-out would never be reserved, and scsi_timeout() 'reserved' arg should never be set. Remove handling for reserved requests, drop the wrapper scsi_timeout() as it now just calls scsi_times_out() always, and finally rename scsi_times_out() -> scsi_timeout() to match the blk_mq_ops method name.
