2021-06-02scsi: mpi3mr: Add support for threaded ISRKashyap Desai
Register driver for threaded interrupts. By default the driver will attempt I/O completion from interrupt context (primary handler). Since the driver tracks per reply queue outstanding I/Os, it will schedule threaded ISR if there are any outstanding I/Os expected on that particular reply queue. Threaded ISR (secondary handler) will loop for I/O completion as long as there are outstanding I/Os (speculative method using same per reply queue outstanding counter) or it has completed some X amount of commands (something like budget).

2021-06-02scsi: mpi3mr: Add support for timestamp sync with firmwareKashyap Desai
This operation requests that the IOC update the TimeStamp. When the I/O Unit is powered on it sets the TimeStamp field value to 0x0000_0000_0000_0000 and increments the current value every millisecond. A host driver sets the TimeStamp field to the current time by using an IOCInit request. The TimeStamp field is periodically updated by the host driver.

2021-06-02scsi: mpi3mr: Add support for recovering controllerKashyap Desai
Detection of firmware fault or any kind of unresponsiveness in the controller (any admin command which times out) results in resetting the controller. The primary reset mechanisms used are either soft reset or diag fault reset. A reset is performed if the host sets the ResetAction field in the HostDiagnostic register to either 001b (soft reset) or 007b (diag fault reset). After successfully resetting the controller the driver reinitializes the controller by going through start of the day initialization procedure. Pending I/Os during the reset are returned back to the SCSI midlayer for retry.

2021-06-02scsi: mpi3mr: Create operational request and reply queue pairKashyap Desai
Create operational request and reply queue pair. The MPI3 transport interface consists of an Administrative Request Queue, an Administrative Reply Queue, and Operational Messaging Queues. The Operational Messaging Queues are the primary communication mechanism between the host and the I/O Controller (IOC). Request messages, allocated in host memory, identify I/O operations to be performed by the IOC. These operations are queued on an Operational Request Queue by the host driver. Reply descriptors track I/O operations as they complete. The IOC queues these completions in an Operational Reply Queue. To fulfil large contiguous memory requirement, driver creates multiple segments and provide the list of segments. Each segment size should be 4K which is a hardware requirement. An element array is contiguous or segmented. A contiguous element array is located in contiguous physical memory. A contiguous element array must be aligned on an element size boundary. An element's physical address within the array may be directly calculated from the base address, the Producer/Consumer index, and the element size. Expected phased identifier bit is used to find out valid entry on reply queue. Driver sets <ephase> bit and IOC inverts the value of this bit on each pass.

2021-05-31scsi: fas216: Translate message to host byte statusHannes Reinecke
Instead of setting the message byte translate it to the appropriate host byte. As error recovery would return DID_ERROR for any non-zero message byte the translation doesn't change the error handling.

2021-05-31scsi: advansys: Do not set message byte in SCSI statusHannes Reinecke
The host byte in the SCSI status takes precedence during error recovery, so there is no point in setting the message byte in addition to a host byte which is not DID_OK.

2021-05-31scsi: aha152x: Do not set message byte when calling scsi_done()Hannes Reinecke
The done() function is called with a host_byte indicating the actual error when the message byte is set. As the host byte takes precedence during error recovery we can drop setting the message byte if the host byte is set, too. The only other case is when the host byte is DID_OK, but in that case the message byte is always COMMAND_COMPLETE (i.e. 0), so we can drop it there, too.
