This function always returns 0. We can make it return void to simplify the code. Also, no caller ever checks the return value of this function. Link: https://lore.kernel.org/r/20220616080210.18531-1-mgurtovoy@nvidia.comReviewed-by:

Some MediaTek UFS platforms support different VCCQx power rails, for example, both 1.2v and 1.8v VCCQx, in a single kernel image. To optimize the system power consumption, provide a way to disable and release the unused power rail during the device probing.

iscsi_data_xmit() (TX worker) is iterating over the queue of new SCSI commands concurrently with the queue being replenished. Only after the queue is emptied will we start sending pending DataOut PDUs. That leads to DataOut timeout on the target side and to connection reinstatement. Give priority to pending DataOut commands over new commands. Link: https://lore.kernel.org/r/20220607131953.11584-1-d.bogdanov@yadro.comReviewed-by:

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:
