From: Rodrigo Vivi Date: Fri, 16 Jun 2017 22:49:58 +0000 (-0700) Subject: drm/i915/cfl: Introduce Coffee Lake workarounds. X-Git-Tag: v4.14-rc1~8^2~53^2~86 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=46c26662d2fb8377f5d387cf2e5ee3246af780b7;p=platform%2Fkernel%2Flinux-rpi3.git drm/i915/cfl: Introduce Coffee Lake workarounds. Coffee Lake inherit most of Kabylake production workarounds. v2: Fix typo on commit message and remove WaDisableKillLogic and GEN9_DISABLE_OCL_OOB_SUPPRESS_LOGIC, since as Mika pointed out they shouldn't be here for cfl according to BSpec.
