2022-07-14scsi: smartpqi: Add module param to disable managed intsMike McGowen1-1/+1
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.

2022-07-14scsi: smartpqi: Fix PCI control linkdown system hangSagar Biradar1-0/+7
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.

2022-07-14scsi: smartpqi: Shorten drive visibility after removalMike McGowen1-0/+1
Check the response code returned from the LUN reset task management function and if it indicates the LUN is not valid, do not retry. Reduce rescan worker delay to 5 seconds for the event handler only. The removal of a drive from the OS could have been delayed up to 30 seconds after being physically pulled. The driver was retrying a LUN reset 3 times even though the return code indiciated the LUN was no longer valid. There was a 10 second delay between each retry. Additionally, the rescan worker was scheduled to run 10 seconds after the driver received the event.

2022-02-08scsi: smartpqi: Expose SAS address for SATA drivesKevin Barnett1-2/+0
Remove UNIQUE_WWID_IN_REPORT_PHYS_LUN PQI feature. This feature was originally added to solve a problem with NVMe drives, but this problem has since been solved a different way, so this PQI feature is no longer required for any type of drive. The kernel was not creating symbolic links in sysfs between SATA drives and their enclosure. The driver was enabling the UNIQUE_WWID_IN_REPORT_PHYS_LUN PQI feature, which causes the FW to return a WWID for SATA drives that is derived from a unique ID read from the SATA drive itself. The driver was exposing this WWID as the drive's SAS address. However, because this SAS address does not match the SAS address returned by an enclosure's SES Page 0xA data, the Linux kernel was not able to match a SATA drive with its enclosure.

2022-02-08scsi: smartpqi: Update volume size after expansionMahesh Rajashekhara1-0/+1
After modifying logical volume size, lsblk command still shows previous size of logical volume. When the driver gets any event from firmware it schedules rescan worker with delay of 10 seconds. If array expansion is so quick that it gets completed in a second, the driver could not catch logical volume expansion due to worker delay. Since driver does not detect volume expansion, driver would not call rescan device to update new size to the OS.

2022-02-08scsi: smartpqi: Resolve delay issue with PQI_HZ valueBalsundar P1-6/+0
Change PQI_HZ to HZ. PQI_HZ macro was set to 1000 when HZ value is less than 1000. By default, PQI_HZ will result into a delay of 10 seconds(for kernel, which has HZ = 100). So in this case when firmware raises an event, rescan worker will be scheduled after a delay of (10 x PQI_HZ) = 100 seconds instead of 10 seconds. Also driver uses PQI_HZ at many instances, which might result in some other issues with respect to delay.

2021-10-05scsi: smartpqi: Fix duplicate device nodes for tape changersKevin Barnett1-0/+1
Stop the OS from re-discovering multiple LUNs for tape drive and medium changer. Duplicate device nodes for Ultrium tape drive and medium changer are being created. The Ultrium tape drive is a multi-LUN SCSI target. It presents a LUN for the tape drive and a 2nd LUN for the medium changer. Our controller FW lists both LUNs in the RPL results. As a result, the smartpqi driver exposes both devices to the OS. Then the OS does its normal device discovery via the SCSI REPORT LUNS command, which causes it to re-discover both devices a 2nd time, which results in the duplicate device nodes.

2021-08-18scsi: smartpqi: Replace one-element array with flexible-array memberGustavo A. R. Silva1-1/+1
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members"[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code a bit according to the use of a flexible-array member in struct pqi_event_config instead of a one-element array, and use the struct_size() helper. This helps with the ongoing efforts to globally enable -Warray-bounds and get us closer to being able to tighten the FORTIFY_SOURCE routines on memcpy(). This issue was found with the help of Coccinelle and audited and fixed, manually.
