That way we can also unify the interfaces of fc_bsg_jobdone and bsg_job_done.

2016-11-09scsi: megaraid_sas: Send SYNCHRONIZE_CACHE for VD to firmwareKashyap Desai3-5/+10
Until now the megaraid_sas driver has reported successful completion on SYNCHRONIZE_CACHE commands without sending them down to the controller. The controller firmware has been responsible for taking care of flushing disk caches for all drives that belong to a Virtual Disk at the time of system reboot/shutdown. There may have been a reason to avoid sending SYNCHRONIZE_CACHE to a VD in the past but that no longer appears to be valid. Older versions of MegaRaid firmware (Gen2 and Gen2.5) set the WCE bit for Virtual Disks but the firmware does not report correct completion status for a SYNCHRONIZE_CACHE command. As a result, we must use another method to identify whether it is safe to send the command to the controller. We use the canHandleSyncCache firmware flag in the scratch pad register at offset 0xB4. New SYNCHRONIZE_CACHE behavior: IF 'JBOD' Driver sends SYNCHRONIZE_CACHE command to the firmware Firmware sends SYNCHRONIZE_CACHE to drive Firmware obtains status from drive and returns same status back to driver ELSEIF 'VirtualDisk' IF firmware supports new API bit called canHandleSyncCache Driver sends SYNCHRONIZE_CACHE command to the firmware Firmware does not send SYNCHRONIZE_CACHE to drives Firmware returns SUCCESS ELSE Driver does not send SYNCHRONIZE_CACHE command to the firmware Driver return SUCCESS for that command ENDIF ENDIF [mkp: edited patch description] Signed-off-by: Kashyap Desai <kashyap.desai@broadcom.com> Signed-off-by: Sumit Saxena <sumit.saxena@broadcom.com> Reviewed-by: Tomas Henzl <thenzl@redhat.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Ewan D.

2016-11-09scsi: ufs: fix race between clock gating and devfreq scaling workSubhash Jadavani1-0/+32
UFS devfreq clock scaling work may require clocks to be ON if it need to execute some UFS commands hence it may request for clock hold before issuing the command. But if UFS clock gating work is already running in parallel, ungate work would end up waiting for the clock gating work to finish and as clock gating work would also wait for the clock scaling work to finish, we would enter in deadlock state. Here is the call trace during this deadlock state: Workqueue: devfreq_wq devfreq_monitor __switch_to __schedule schedule schedule_timeout wait_for_common wait_for_completion flush_work ufshcd_hold ufshcd_send_uic_cmd ufshcd_dme_get_attr ufs_qcom_set_dme_vs_core_clk_ctrl_clear_div ufs_qcom_clk_scale_notify ufshcd_scale_clks ufshcd_devfreq_target update_devfreq devfreq_monitor process_one_work worker_thread kthread ret_from_fork Workqueue: events ufshcd_gate_work __switch_to __schedule schedule schedule_preempt_disabled __mutex_lock_slowpath mutex_lock devfreq_monitor_suspend devfreq_simple_ondemand_handler devfreq_suspend_device ufshcd_gate_work process_one_work worker_thread kthread ret_from_fork Workqueue: events ufshcd_ungate_work __switch_to __schedule schedule schedule_timeout wait_for_common wait_for_completion flush_work __cancel_work_timer cancel_delayed_work_sync ufshcd_ungate_work process_one_work worker_thread kthread ret_from_fork This change fixes this deadlock by doing this in devfreq work (devfreq_wq): Try cancelling clock gating work. If we are able to cancel gating work or it wasn't scheduled, hold the clock reference count until scaling is in progress. If gate work is already running in parallel, let's skip the frequecy scaling at this time and it will be retried once next scaling window expires.

An UNMAP command on a PI formatted device will leave the Logical Block Application Tag and Logical Block Reference Tag as all F's (for those LBAs that are unmapped). To avoid IO errors if those LBAs are subsequently read before they are written with valid tag fields, the MPI SCSI IO requests need to set the EEDPFlags element EEDP Escape Mode field, Bits [7:6] appropriately. A value of 2 should be set to disable all PI checks if the Logical Block Application Tag is 0xFFFF for PI types 1 and 2. A value of 3 should be set to disable all PI checks if the Logical Block Application Tag is 0xFFFF and the Logical Block Reference Tag is 0xFFFFFFFF for PI type 3.
