[PATCH 0/6] hisi_sas: v2 hw SoC bug workarounds

From: John Garry
Date: Mon Apr 10 2017 - 08:53:40 EST


This patchset introduces some v2 hw bug workarounds. Mostly
they are related to SATA devices, but there is also a
workaround for a scenario when internal abort command may
timeout.

The general rule for implementing workarounds was to do it
in the hw layer, as the next hw revision should not
include these bugs, so it is better not pollute the driver
main layer with workarounds

This patchset also includes 2 other patches, one for a
possible NULL pointer deference and another for resetting
the controller for fatal AXI/ECC errors.

John Garry (2):
scsi: hisi_sas: add v2 hw internal abort timeout workaround
scsi: hisi_sas: fix NULL deference when TMF timeouts

Xiang Chen (1):
scsi: hisi_sas: controller reset for multi-bits ECC and AXI fatal
errors

Xiaofei Tan (3):
scsi: hisi_sas: workaround STP link SoC bug
scsi: hisi_sas: workaround a SoC SATA IO processing bug
scsi: hisi_sas: workaround SoC about abort timeout bug
