| * scsi: handle zone resources errorsDamien Le Moal2020-10-131-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ZBC or ZAC disks that have a limit on the number of open zones may fail a zone open command or a write to a zone that is not already implicitly or explicitly open if the total number of open zones is already at the maximum allowed. For these operations, instead of returning the generic BLK_STS_IOERR, return BLK_STS_ZONE_OPEN_RESOURCE which is returned as -ETOOMANYREFS to the I/O issuer, allowing the device user to act appropriately on these relatively benign zone resource errors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current driver uses fixed number of Inbound and Outbound queues and all of the I/O, TMF and internal requests are submitted through those. A global spin lock is used to control the shared access. This can create a lock contention and it is real bottleneck in the I/O path. To avoid this, the number of supported Inbound and Outbound queues is increased to 64, and the number of queues used is decided based on number of CPU cores online and number of MSI-X vectors allocated. Also add locks per queue instead of using the global lock.

This doesn't matter for any of the platforms it runs on currently, but that will change soon. To help with this two new helpers to transfer ownership to and from the device are added that abstract the syncing of the non-coherent memory. The two current bidirectional cases are mapped to transfers to the device, as that appears to what they are used for. Note that for parisc, which is the only architecture this driver needs to use non-coherent memory on, the direction argument of dma_cache_sync is ignored, so this will not change behavior in any way.
