2021-04-06scsi: smartpqi: Update RAID bypass handlingKevin Barnett1-4/+0
Simplify AIO retry management by removing retry list and list management. Need to retry is already set in the response status. Also remove the bypass worker thread. Accelerated I/O requests bypass the RAID engine and go directly to either an HBA disk or to a physical component of a RAID volume.

2021-04-06scsi: smartpqi: Add stream detectionDon Brace1-0/+9
Enhance performance by adding sequential stream detection for RAID5/RAID6 sequential write requests. Reduce stripe lock contention with full-stripe write operations. There is one common stripe lock for each RAID volume that can be set by either the RAID engine or the AIO engine. The AIO path has I/O request sizes well below the stripe size resulting in many Read-Modify-Write operations. Sending the request to the RAID engine allows for coalescing requests into full stripe operations resulting in reduced Read-Modify-Write operations.

2018-12-20scsi: smartpqi: add support for PQI Config Table handshakeKevin Barnett1-0/+43
Add support for new IUs and parsing of the Firmware Features section of the PQI Config Table to implement the "handshake" between the driver and firmware to communicate firmware features supported and enabled by the driver.

2017-07-18scsi: smartpqi: limit transfer length to 1MBYadan Fan1-1/+1
The smartpqi firmware will bypass the cache for any request larger than 1MB, so we should cap the request size to avoid any performance degradation in kernels later than v4.3 This degradation is caused from d2be537c3ba3568acd79cd178327b842e60d035e, which changed max_sectors_kb to 1280k, but the hardware is able to work fine with it, so the true fix should be from smartpqi driver.
