If a firmware update adds support for the trigger pages, then the driver should handle this by writing the existing trigger data from the driver's internal data structure to the corresponding trigger pages in NVRAM. Also handle the case where the trigger page capability is no longer present after a firmware downgrade.

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.

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.

NCR5380_poll_politely2() uses in_interrupt() and irqs_disabled() to check if it is safe to sleep. Such usage in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated, or the context be explicitly conveyed in an argument passed by the caller. Below is a context analysis of NCR5380_poll_politely2() uppermost callers: - NCR5380_maybe_reset_bus(), task, invoked during device probe. -> NCR5380_poll_politely() -> do_abort() - NCR5380_select(), task, but can only sleep in the "release, then re-acquire" regions of the spinlock held by its caller. Sleeping invocations (lock released): -> NCR5380_poll_politely2() Atomic invocations (lock acquired): -> NCR5380_reselect() -> NCR5380_poll_politely() -> do_abort() -> NCR5380_transfer_pio() - NCR5380_intr(), interrupt handler -> NCR5380_dma_complete() -> NCR5380_transfer_pio() -> NCR5380_poll_politely() -> NCR5380_reselect() (see above) - NCR5380_information_transfer(), task, but can only sleep in the "release, then re-acquire" regions of the caller-held spinlock. Sleeping invocations (lock released): - NCR5380_transfer_pio() -> NCR5380_poll_politely() - NCR5380_poll_politely() Atomic invocations (lock acquired): - NCR5380_transfer_dma() -> NCR5380_dma_recv_setup() => generic_NCR5380_precv() -> NCR5380_poll_politely() => macscsi_pread() -> NCR5380_poll_politely() -> NCR5380_dma_send_setup() => generic_NCR5380_psend -> NCR5380_poll_politely2() => macscsi_pwrite() -> NCR5380_poll_politely() -> NCR5380_poll_politely2() -> NCR5380_dma_complete() -> NCR5380_transfer_pio() -> NCR5380_poll_politely() - NCR5380_transfer_pio() -> NCR5380_poll_politely - NCR5380_reselect(), atomic, always called with hostdata spinlock held. Since NCR5380_poll_politely2() already takes a "wait" argument in jiffies, use it to determine if the function can sleep. Modify atomic callers, which passed an unused wait value in terms of HZ, to pass zero.

In current task abort routine, if task abort happens to the device W-LUN, the code directly jumps to ufshcd_eh_host_reset_handler() to perform a full reset and restore then returns FAIL or SUCCESS. Commands sent to the device W-LUN are most likely the SSU cmds sent during UFS PM operations. If such SSU cmd enters task abort routine when ufshcd_eh_host_reset_handler() flushes eh_work, it will get stuck there since err_handler is serialized with PM operations. In order to unblock above call path, we merely clean up the lrb taken by this cmd, queue the eh_work and return SUCCESS. Once the cmd is aborted, the PM operation which sends out the cmd just errors out, then err_handler shall be able to proceed with the full reset and restore. In this scenario, the cmd is aborted even before it is actually cleared by HW, set the lrb->in_use flag to prevent subsequent cmds, including SCSI cmds and dev cmds, from taking the lrb released from abort. The flag shall evetually be cleared in __ufshcd_transfer_req_compl() invoked by the full reset and restore from err_handler.

UFS specficication allows different VCC configurations for UFS devices, for example: (1). 2.70V - 3.60V (Activated by default in UFS core driver) (2). 1.70V - 1.95V (Activated if "vcc-supply-1p8" is declared in device tree) (3). 2.40V - 2.70V (Supported since UFS 3.x) With the introduction of UFS 3.x products, an issue is happening that UFS driver will use wrong "min_uV-max_uV" values to configure the voltage of VCC regulator on UFU 3.x products with the configuration (3) used. To solve this issue, we simply remove pre-defined initial VCC voltage values in UFS core driver with below reasons, 1. UFS specifications do not define how to detect the VCC configuration supported by attached device. 2. Device tree already supports standard regulator properties. Therefore VCC voltage shall be defined correctly in device tree, and shall not changed by UFS driver. What UFS driver needs to do is simply enable or disable the VCC regulator only. Similar change is applied to VCCQ and VCCQ2 as well. Note that we keep struct ufs_vreg unchanged. This allows vendors to configure proper min_uV and max_uV of any regulators to make regulator_set_voltage() works during regulator toggling flow in the future. Without specific vendor configurations, min_uV and max_uV will be NULL by default and UFS core driver will enable or disable the regulator only without adjusting its voltage.
