Title:
AACRAID for power9 platform
Status in The Ubuntu-power-systems project:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Zesty:

Bug description:
SRU Justification
Impact: Various issues found during integration of Microsemi adapters
on Power 8 and Power 9 systems.
Fix: Update the aacraid driver to version 50834 by cherry picking
patches from upstream and from linux-next.
Test case: Updated driver has been tested by IBM on Power systems and
regression tested by Microsemi on other platforms.
Regression potential: Changes (aside from trivial typo fixes) are
limited to aacraid driver, so there's no regression potential outside
of this driver. Regression testing has been done by Microsemi on
relevant platforms.

Hello team,
It seems Microsemi team has requested to backport few AACRAID driver patches
for Power 9 platform for 17.04 and 16.04.3 kernel.
Hi Narinder,
We have submitted a handful of critical fixes for the AACRAID driver
on to the kernel.org, targeting 4.11. These patches are bug fixes and
our customer IBM is expecting these patches to go into the 16.04.3
release, for to use with the Power9 platforms.
Can you please let me know if these patches will be backported by your
kernel team on to the upcoming 16.04.3? Do you also have a schedule in
place for 16.04.3 release?
Thanks,
Gana
Below are the patch details.
Subject: [PATCH V2 00/19] aacraid: Patchset with reset rework and misc
fixes
This patchset primarily focuses on tweaking and hardening the
controller reset support for both ARC and HBA1000 devices. Now the
driver can only reset the controller thru eh reset. Included a srb
memory fix and pci dma allocation fix.
Changes in V2:
- Corrected heading and description for srb memory patch and removed stray
comment.
- Removed incorrect up function call and cleared fib wait flag after call
to down interruptible in the ioctl return on ctrl reset patch.
- Added review acknowledgements by David Carroll thank you Dave for
finding the above issues in the above 2 patches.
