From 185c66e57ce725afeb58a3cfa48547706af3a7af Mon Sep 17 00:00:00 2001 From: Mika Kuoppala Date: Tue, 5 Apr 2016 15:56:16 +0300 Subject: [PATCH] drm/i915/skl: Fix rc6 based gpu/system hang 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.
