| * scsi: ufs: core: Simplify driver shutdownBart Van Assche2023-06-0113-53/+5
| | | | | | | | | | | | | | | | | | | | | | All UFS host drivers call ufshcd_shutdown(). Hence, instead of calling ufshcd_shutdown() from the host driver .shutdown() callback, inline that function into ufshcd_wl_shutdown().

| * scsi: ufs: core: Fix handling of lrbp->cmdBart Van Assche2023-06-011-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ufshcd_queuecommand() may be called two times in a row for a SCSI command before it is completed. Hence make the following changes: - In the functions that submit a command, do not check the old value of lrbp->cmd nor clear lrbp->cmd in error paths. - In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd. See also scsi_send_eh_cmnd(). This commit prevents that the following appears if a command times out: WARNING: at drivers/ufs/core/ufshcd.c:2965 ufshcd_queuecommand+0x6f8/0x9a8 Call trace: ufshcd_queuecommand+0x6f8/0x9a8 scsi_send_eh_cmnd+0x2c0/0x960 scsi_eh_test_devices+0x100/0x314 scsi_eh_ready_devs+0xd90/0x114c scsi_error_handler+0x2b4/0xb70 kthread+0x16c/0x1e0 Fixes: 5a0b0cb9bee7 ("[SCSI] ufs: Add support for sending NOP OUT UPIU") Signed-off-by: Bart Van Assche <bvanassche@acm.org> Link: https://lore.kernel.org/r/20230524203659.1394307-3-bvanassche@acm.org Acked-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Martin K.

| * scsi: ufs: core: Increase the START STOP UNIT timeout from one to ten secondsBart Van Assche2023-06-011-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One UFS vendor asked to increase the UFS timeout from 1 s to 3 s. Another UFS vendor asked to increase the UFS timeout from 1 s to 10 s. Hence this patch that increases the UFS timeout to 10 s. This patch can cause the total timeout to exceed 20 s, the Android shutdown timeout. This is fine since the loop around ufshcd_execute_start_stop() exists to deal with unit attentions and because unit attentions are reported quickly.

This bit mask mechanism does not scale well in MCQ mode when the queue depth becomes much greater than 64. Change the 2nd parameter to the function to be the task_tag number of the corresponding bit to be cleared in the door bell register. By doing so, MCQ mode with a large queue depth can reuse this function. Since the behavior of this function is changed from handling multiple commands into a single command, rename ufshcd_clear_cmds() into ufshcd_clear_cmd(). Signed-off-by: Bao D.

Command requeueing makes it harder than necessary to preserve the command order. Hence this patch series that modifies the SCSI core and also the UFS driver such that clock ungating does not trigger command requeueing.

This is suboptimal. Allow ufshcd_queuecommand() to sleep such that clock ungating does not trigger command requeuing. Remove the ufshcd_scsi_block_requests() and ufshcd_scsi_unblock_requests() calls because these are no longer needed. The flush_work(&hba->clk_gating.ungate_work) call is sufficient to make the SCSI core wait for clock ungating to complete.
