During controller reset, the driver tries to flush all the pending firmware event works from worker queue that are queued prior to the reset. However, if any work is waiting for device addition/removal operation to be completed at the SML, then a deadlock is observed. This is due to the controller reset waiting for the device addition/removal to be completed and the device/addition removal is waiting for the controller reset to be completed. To limit this deadlock, continue with the controller reset handling without canceling the work which is waiting for device addition/removal operation to complete at SML.

Driver added a new dev_pm_ops structure used only if CONFIG_PM is set. The CONFIG_PM MACRO needed to be moved up in the code to avoid the compiler warnings. The hunk to move the location was missing from the above patch. Found by kernel test robot by building driver with CONFIG_PM disabled.

In the queue path, move around when we assign sas_task->lldd_task such that this pointer and the SAS_TASK_AT_INITIATOR flag are set atomically. It is also not required to clear SAS_TASK_AT_INITIATOR in isci_task_execute_task() error path as it is also cleared immediately after in isci_task_refuse() call. Now the following items may be considered: - SAS_TASK_STATE_DONE and SAS_TASK_AT_INITIATOR are mutually exclusive apart from possibly when SAS_TASK_STATE_DONE is set in sas_scsi_find_task(), but that is after .lldd_abort_task, i.e. the considered callback, is called. - If isci_task_refuse() is called in the queue path, then sas_task->lldd_task and SAS_TASK_AT_INITIATOR are cleared atomically in isci_task_refuse(). - In the completion path, SAS_TASK_STATE_DONE is set and SAS_TASK_AT_INITIATOR is cleared atomically before the sas_task.lldd_task is cleared later. So in isci_task_abort_task() if SAS_TASK_STATE_DONE is not set and sas_task.lldd_task is still set, then SAS_TASK_AT_INITIATOR must be set - so we can drop this check on SAS_TASK_AT_INITIATOR.

Correct NUMA node association when calling pqi_pci_probe(). In the function pqi_pci_probe(), the driver makes an OS call to get the NUMA node associated with a controller. If the call returns that there is no associated node, the driver attempts to set it to node 0. The problem is that a different local variable (cp_node) was being used to do this, but the original local variable (node) was still being used in the call to pqi_alloc_ctrl_info(). The value of "node" is not updated if the conditional after the call to dev_to_node() evaluates to TRUE.

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.

Use all data disks for sequential read operations. Testing discovered inconsistent performance on RAID 10 volumes when performing 256K sequential reads. The driver was only using a single tracker to determine which physical drive to send a request to for AIO requests.

Avoid dropping into shell if the controller is in locked up state. Driver issues SIS soft reset to bring back the controller to SIS mode while OS boots into kdump mode. If the controller is in lockup state, SIS soft reset does not work. Since the controller lockup code has not been cleared, driver considers the firmware is no longer up and running. Driver returns back an error code to OS and the kdump fails. Link: https://lore.kernel.org/r/164375212337.440833.11955356190354940369.stgit@brunhilda.pdev.netReviewed-by:

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.

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.

Use correct pqi_aio_path_request structure to calculate the offset to sg_descriptors. The function pqi_aio_submit_io() uses the pqi_raid_path_request structure to calculate the offset of the structure member sg_descriptors. This is incorrect. It should be using the pqi_aio_path_request structure instead. This typo is benign because the offsets are the same in both structures.

If a SCSI device handler module is loaded after some SCSI devices have already been probed (e.g. via request_module() by dm-multipath), the "access_state" and "preferred_path" sysfs attributes remain invisible for these devices, although the handler is attached and live. The reason is that the visibility is only checked when the sysfs attribute group is first created. This results in an inconsistent user experience depending on the load order of SCSI low-level drivers vs. device handler modules. This patch changes user space API: attempting to read the "access_state" or "preferred_path" attributes will now result in -EINVAL rather than -ENODEV for devices that have no device handler, and tests for the existence of these attributes will have a different result.
