[v2,00/24] Introducing mpi3mr driver

Message

Kashyap Desai April 7, 2021, 2:04 a.m. UTC

v1->v2
 - removed undefined entries from mpi30_type.h
 - removed DRV_CMD_CALLBACK typedef
 - Use IRQF_SHARED  instead of IRQF_ONESHOT
 - Use READ_ONCE, WRITE_ONCE while accessing operational request
   queue consumer index 
 - removed in_interrup()
 - remove pr_cont.
 - move some code from error handling to device handling patch.
 - used direct values instead of macro MPI3_SECTOR_SIZE_XYZ
 - Add Hannes's reviewed-tag to appropriate patches
 - Add Reported-by kernel test robot <[e-mail]> to appropriate
   patches.


This patch series covers logical patches of the new device driver for the
MPI3MR high performance storage I/O & RAID controllers (Avenger series).
The mpi3mr has true multiple h/w queue interfacing like nvme.

See more info -
https://www.spinics.net/lists/linux-scsi/msg147868.html

The controllers managed by the mpi3mr driver are capable of reaching a
very high performance numbers compared to existing controller due to the
new hardware architectures. This Driver is tested with the internal
versions of the MPI3MR I/O & RAID controllers.

Patches are logical split mainly for better code review. Full patch set is
required for functional stability of this new driver.
