Subject: [PATCH] drm/i915/gen9: Reintroduce WaEnableYV12BugFixInHalfSliceChicken7
Date: Fri, 12 May 2017 13:20:15 +0200 [thread overview]
Message-ID: <20170512112015.19082-1-arkadiusz.hiler@intel.com> (raw)
This basically reverts commit 465418c6064c
("drm/i915/gen9: Remove WaEnableYV12BugFixInHalfSliceChicken7")
with small addition - marking it as affecting KBL as well.
It was incorrectly considered fixed in production steppings.
