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:

When we are resuming the UFS device rails in HPM mode, we are first powering on the VCC rail while VCCQ and VCCQ2 rails still being in LPM mode. Some UFS devices may take VCC on event as hint that host wants UFS device to be resumed and may start drawing more power from the VCCQ/VCCQ2 rails (while they are still in LPM mode) causing voltage drop on these rails. This change fixes this issue by bringing VCCQ & VCCQ2 rails out of LPM before powering on VCC rail. Reviewed-by:

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. Reviewed-by:

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. Signed-off-by:

scsi: mpt3sas: Fix for incorrect numbers for MSIX vectors enabled when non RDPQ card is enumerated first. No. of MSIX vectors supported = min (Total no. of CPU cores, MSIX vectors supported by card) when RDPQ is disabled "max_msix_vectors" module parameter which was declared as global was set to '8' and hence if there are more than one card in system among which if RDPQ disabled card is enumerated first then only 8 MSIX vectors was getting enabled for all the cards(including RDPQ enabled card,which can support more than 8 MSIX vectors). Used local variable instead of global variable ,if RDPQ is disabled this local variable is set to '8' else it is set to "max_msix_vectors" (by default this is set to -1, whose value can be set by user during driver load time).So now regardless of whether RDPQ disabled card is enumerated first or RDPQ enabled card is enumerated first , MSIX vectors enabled depends on the cards capability.

The advansys probe function tries to handle both ISA and PCI cases, each hidden in an #ifdef when unused. This leads to a warning indicating that when PCI is disabled we could be using uninitialized data: drivers/scsi/advansys.c: In function advansys_board_found : drivers/scsi/advansys.c:11036:5: error: ret may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/scsi/advansys.c:10928:28: note: ret was declared here drivers/scsi/advansys.c:11309:8: error: share_irq may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/scsi/advansys.c:10928:6: note: share_irq was declared here This cannot happen in practice because the hardware in question only exists for PCI, but changing the code to just error out here is better for consistency and avoids the warning.

With the error message I added in "libfc: sanity check cpu number extracted from xid" I didn't account for the fact that fc_exch_find is called with FC_XID_UNKNOWN at the start of a new exchange if we are the responder. It doesn't come up with the initiator much, but that's basically every exchange for a target. By checking the xid for FC_XID_UNKNOWN first, we not only prevent the erroneous error message, but skip the unnecessary lookup attempt as well.

Venkat Gopalakrishnan authored
The ungate work turns on the clock before it exits hibern8, if the link was put in hibern8 during clock gating work. There occurs a race condition when clock scaling work calls ufshcd_hold() to make sure low power states cannot be entered, but that returns by checking only whether the clocks are on. This causes the clock scaling work to issue UIC commands when the link is in hibern8 causing failures. Make sure we exit hibern8 state before returning from ufshcd_hold(). Callstacks for race condition: ufshcd_scale_gear ufshcd_devfreq_scale ufshcd_devfreq_target update_devfreq devfreq_monitor process_one_work worker_thread kthread ret_from_fork ufshcd_uic_hibern8_exit ufshcd_ungate_work process_one_work worker_thread kthread ret_from_fork Signed-off-by:

During runtime resume operation, clock scaling may get indirectly resumed via call to ufshcd_set_dev_pwr_mode(): Start/Stop Unit command times out and SCSI error handling ultimately calls the host reset handler to recover, during which clock scaling is resumed. Error case exit path of runtime resume will disable clocks. As clock scaling was already resumed, it will get scheduled later on and try to access UFS registers while clocks are disabled, resulting in unclocked register access. Signed-off-by:
