git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi Pull SCSI fixes from James Bottomley: "This is a load of driver fixes (12 ufs, 1 mpt3sas, 1 cxgbi). The big core two fixes are for power management ("block: Do not accept any requests while suspended" and "block: Fix a race in the runtime power management code") which finally sorts out the resume problems we've occasionally been having. To make the resume fix, there are seven necessary precursors which effectively renames REQ_PREEMPT to REQ_PM, so every "special" request in block is automatically a power management exempt one. All of the non-PM preempt cases are removed except for the one in the SCSI Parallel Interface (spi) domain validation which is a genuine case where we have to run requests at high priority to validate the bus so this becomes an autopm get/put protected request" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (22 commits) scsi: cxgb4i: Fix TLS dependency scsi: ufs: Un-inline ufshcd_vops_device_reset function scsi: ufs: Re-enable WriteBooster after device reset scsi: ufs-mediatek: Use correct path to fix compile error scsi: mpt3sas: Signedness bug in _base_get_diag_triggers() scsi: block: Do not accept any requests while suspended scsi: block: Remove RQF_PREEMPT and BLK_MQ_REQ_PREEMPT scsi: core: Only process PM requests if rpm_status != RPM_ACTIVE scsi: scsi_transport_spi: Set RQF_PM for domain validation commands scsi: ide: Mark power management requests with RQF_PM instead of RQF_PREEMPT scsi: ide: Do not set the RQF_PREEMPT flag for sense requests scsi: block: Introduce BLK_MQ_REQ_PM scsi: block: Fix a race in the runtime power management code scsi: ufs-pci: Enable UFSHCD_CAP_RPM_AUTOSUSPEND for Intel controllers scsi: ufs-pci: Fix recovery from hibernate exit errors for Intel controllers scsi: ufs-pci: Ensure UFS device is in PowerDown mode for suspend-to-disk ->poweroff() scsi: ufs-pci: Fix restore from S4 for Intel controllers scsi: ufs-mediatek: Keep VCC always-on for specific devices scsi: ufs: Allow regulators being always-on scsi: ufs: Clear UAC for RPMB after ufshcd resets ...

2020-12-12sr: Remove in_interrupt() usage in sr_init_command().Sebastian Andrzej Siewior
The in_interrupt() check in sr_init_command() is a leftover from the past, pre v2.3.16 era to be exact. Back then the ioctl() was served by `sr' itself and sector size changes by CDROMREADMODE2 (as noted in the comment) were accounted within sr's data structures which allowed a "lazy" reset so it could be skipped on the next request and reset back to the default value once the device node was closed or before a command from the blockqueue was issued. This does not work like that anymore. The CDROMREADMODE2 is served by cdrom's mmc_ioctl() function which may change the sector size but the `sr' driver does not learn about it and so its ->sector_size is not updated. The ioctl() resets the changed sector size back to 2048. sr_read_sector() also resets the sector size back to the default once it is done. Remove the conditional sector size update from sr_init_command() and sr_release() because it is not needed.

2020-12-12sr: Switch the sector size back to 2048 if sr_read_sector() changed it.Sebastian Andrzej Siewior
sr_read_sector() is hardly used since v2.3.16. Its only purpose is to check if it is a XA medium via sr_is_xa(). This check is only enabled if the module parameter `xa_test' is enabled. Change the sector size back to 2048 if it was changed. With this change, there is no lazy sector size changing left.

storvsc_on_channel_callback()" This reverts commit 3b8c72d076c42bf27284cda7b2b2b522810686f8. Dexuan reported a regression where StorVSC fails to probe a device (and where, consequently, the VM may fail to boot). The root-cause analysis led to a long-standing race condition that is exposed by the validation /commit in question. Let's put the new validation aside until a proper solution for that race condition is in place.

UFS 3.1 specification mentions that the WriteBooster flags listed below will be set to their default values, i.e. disabled, after power cycle or any type of reset event. Thus we need to reset the flag variables kept in struct hba to align with the device status and ensure that WriteBooster-related functions are configured properly after device reset. Without this fix, WriteBooster will not be enabled successfully after by ufshcd_wb_ctrl() after device reset because hba->wb_enabled remains true.

2020-12-09scsi: ufs-pci: Fix restore from S4 for Intel controllersAdrian Hunter
Currently, ufshcd-pci is the only UFS driver with support for suspend-to-disk PM callbacks (i.e. freeze/thaw/restore/poweroff). These callbacks are set by the macro SET_SYSTEM_SLEEP_PM_OPS to the same functions as system suspend/resume. That will work with spm_lvl 5 because spm_lvl 5 will result in a full restore for the ->restore() callback. In the absence of a full restore, the host controller registers will have values set up by the restore kernel (the kernel that boots and loads the restore image) which are not necessarily the same. However it turns out, the only registers that sometimes need restore are the base address registers. This has gone un-noticed because, depending on IOMMU settings, the kernel can end up allocating the same addresses every time. For Intel controllers, an spm_lvl other than 5 can be used, so to support S4 (suspend-to-disk) with spm_lvl other than 5, restore the base address registers.

2020-12-09scsi: mpt3sas: Add persistent trigger pages supportSuganath Prabu S
The user can set trigger values in order to collect the IOC's host trace buffer automatically upon detecting certain conditions. However, the trigger values that the user sets are not persistent across system reboot or reload of the driver. In order to make the user trigger settings persistent, these trigger values need to be saved in the IOC's NVRAM pages: - Driver Persistent Trigger Page 0: This page is used to store list of trigger types that are enabled - Driver Persistent Trigger Page 1: This page stores the list of Master triggers that are enabled - Driver Persistent Trigger Page 2: This page stores the list of MPI Event Triggers that are enabled - Driver Persistent Trigger Page 3: This page stores the list of SCSI Sense Triggers that are enabled - Driver Persistent Trigger Page 4: This page stores the list of IOCStatus-LogInfo Triggers that are enabled. Whenever user configures triggers, the driver persists the values in the corresponding trigger pages. When the driver is subsequently reloaded, the driver reads the values from the trigger pages and configures the triggers accordingly. During firmware upload operation, if the newer firmware supports the trigger page feature, then driver persists the configured diag trigger values to NVRAM.

2020-12-09scsi: mpt3sas: Sync time periodically between driver and firmwareSuganath Prabu S
The controller time currently gets updated with host time during driver load or when a controller reset is issued. I.e. when host issues the IOCInit request message to the HBA firmware. This IOCInit message has a field named 'TimeStamp' with which the host updates the controller time. Sometimes controller time drifts with respect to the host and it is difficult to correlate host logs with controller logs. Issuing a controller reset to sync the time would impact in-flight I/O and is not a viable option. Instead the driver now sends an IO_UNIT_CONTROL Request to sync the time periodically. This is done from the watchdog thread which gets invoked every second. The time synchronization interval is specified in the 'TimeSyncInterval' field in Manufacturing Page11 by the controller: TimeSyncInterval - 8 bits bits 0-6: Time stamp Synchronization interval value bit 7: Time stamp Synchronization interval unit, (if this bit is one then Timestamp Synchronization interval value is specified in terms of hours else Timestamp Synchronization interval value is specified in terms of minutes). The driver keeps track of the timer using IOC's timestamp_update_count field. This field value gets incremented whenever the watchdog thread gets invoked. And whenever this field value is greater than or equal to the Time Stamp Synchronization interval value, the driver sends the IO_UNIT_CONTROL Request message to controller to update the time and then it resets the timestamp_update_count field to zero.
