In commit 05c6c029 ("scsi: pm80xx: Increase number of supported queues"), support for 80xx chip was improved by enabling multiple HW queues. In this, like other SCSI MQ HBA drivers at the time, the HW queues were not exposed to upper layer, and instead the driver managed the queues internally. However, this management duplicates blk-mq code. In addition, the HW queue management is sub-optimal for a system where the number of CPUs exceeds the HW queues - this is because queues are selected in a round-robin fashion, when it would be better to make adjacent CPUs submit on the same queue. And finally, the affinity of the completion queue interrupts is not set to mirror the cpu<->HQ queue mapping, which is suboptimal. As such, for when MSIX is supported, expose HW queues to upper layer. We always use queue index #0 for "internal" commands, i.e. anything which does not come from the block layer, so omit this from the affinity spreading.

In pm8001_tag_alloc() we don't require atomic set_bit() as we are already in atomic context. In pm8001_tag_free() we should use the same host spinlock to protect clearing the tag (and then don't require the atomic clear_bit()).

The current code is buggy in that the tags are set up after they are needed in pm80xx_chip_init() -> pm80xx_set_sas_protocol_timer_config(). The tag depth is earlier read in pm80xx_chip_init() -> read_main_config_table(). Add a post init callback to do the pm80xx work which needs to be done after reading the tags. I don't see a better way to do this. Link: https://lore.kernel.org/r/1654879602-33497-3-git-send-email-john.garry@huawei.comTested-by:

Some values in pm8001_prep_sas_ha_init() are set the same as they would be set in scsi_host_alloc(), or could be in the sht (which would be better), or later just overwritten, so rework the following: - cmd_per_lun can be set in the sht - max_lun and max_channel are as scsi_host_alloc() (so no need to set) - can_queue is later overwritten (so don't set in pm8001_prep_sas_ha_init()) Link: https://lore.kernel.org/r/1654879602-33497-2-git-send-email-john.garry@huawei.comTested-by:

User experience slow recovery when target device went through a stop/start of the authentication application (app_stop/app_start). Between the period of app_stop and app_start on the target device, target device choose to send ELS Reject for any receive AUTH ELS command. At this time, authentication application does not do ELS reject if it encounters error. Therefore, AUTH ELS reject signify authentication application is not running. If driver passes up the AUTH ELS Reject to the authentication application, then it would result in authentication application retrying/resending the same AUTH ELS command again + delay. As a work around, driver should trigger a session tear down where it tells the local authentication application to also tear down. At the next relogin, both sides are then synchronized.

The scenario is this: User loaded driver but has not started authentication app. All sessions to secure device will exhaust all login attempts, fail, and in stay in deleted state. Then some time later the app is started. The driver will replenish the login retry count, trigger delete to prepare for secure login. After deletion, relogin is triggered. For the session that is already deleted, the delete trigger is a no-op. If none of the sessions trigger a relogin, no progress is made. Add a relogin trigger.
