2017-01-11scsi: cxlflash: Cleanup printsMatthew R. Ochs4-338/+346
The usage of prints within the cxlflash driver is inconsistent. This hinders debug and makes the driver source and log output appear sloppy. The following cleanups help unify the prints within cxlflash: - move all prints to dev-* where possible - transition all hex prints to lowercase - standardize variable prints in debug output - derive pointers in a consistent manner - change int to bool where appropriate - remove superfluous data from prints and print statements that do not make sense Signed-off-by: Matthew R.

2017-01-11scsi: cxlflash: Support SQ Command ModeMatthew R. Ochs5-13/+153
The SISLite specification outlines a new queuing model to improve over the MMIO-based IOARRIN model that exists today. This new model uses a submission queue that exists in host memory and is shared with the device. Each entry in the queue is an IOARCB that describes a transfer request. When requests are submitted, IOARCBs ('current' position tracked in host software) are populated and the submission queue tail pointer is then updated via MMIO to make the device aware of the requests.

2017-01-10scsi: megaraid_sas: SAS3.5 Generic Megaraid Controllers Fast Path for RAID ↵Sasikumar Chandrasekaran4-53/+329
1/10 Writes To improve RAID 1/10 Write performance, OS drivers need to issue the required Write IOs as Fast Path IOs (after the appropriate checks allowing Fast Path to be used) to the appropriate physical drives (translated from the OS logical IO) and wait for all Write IOs to complete. Design: A write IO on RAID volume will be examined if it can be sent in Fast Path based on IO size and starting LBA and ending LBA falling on to a Physical Drive boundary. If the underlying RAID volume is a RAID 1/10, driver issues two fast path write IOs one for each corresponding physical drive after computing the corresponding start LBA for each physical drive. Both write IOs will have the same payload and are posted to HW such that replies land in the same reply queue. If there are no resources available for sending two IOs, driver will send the original IO from SCSI layer to RAID volume through the Firmware. Based on PCI bandwidth and write payload, every second this feature is enabled/disabled. When both IOs are completed by HW, the resources will be released and SCSI IO completion handler will be called.

IO Coalescing Detect sequential Write IOs and pass the hint that it is part of sequential stream to help HBA Firmware do the Full Stripe Writes. For read IOs on certain RAID volumes like Read Ahead volumes,this will help driver to send it to Firmware even if the IOs can potentially be sent to hardware directly (called fast path) bypassing firmware. Design: 8 streams are maintained per RAID volume as per the combined firmware/driver design. When there is no stream detected the LRU stream is used for next potential stream and LRU/MRU map is updated to make this as MRU stream. Every time a stream is detected the MRU map is updated to make the current stream as MRU stream.

To avoid IO errors if those LBAs are subsequently read before they are written with valid tag fields, the MPI SCSI IO requests need to set the EEDPFlags element EEDP Escape Mode field, Bits [7:6] appropriately. A value of 2 should be set to disable all PI checks if the Logical Block Application Tag is 0xFFFF for PI types 1 and 2.
