Subject: [PATCH 1/2] drm/i915/skl: Fix rc6 based gpu/system hang
Date: Tue,  5 Apr 2016 15:56:16 +0300	[thread overview]
Message-ID: <1459860977-27751-1-git-send-email-mika.kuoppala@intel.com> (raw)

For all gt3 and gt4 skylake variants, extend the usage of
WaRsDisableCoarsePowerGating for all revisions. Without this
gt3 and gt4 skylakes up to atleast rev 0xa can gpu hang or
system hang.
