It needs a backport of an upstream commit from 4.3, modified to work on 4.2-based i915_bpo: commit f015c5518879fb3e578caaa63806617468a24045 Author: Ville Syrjälä <ville.syrj...@linux.intel.com> Date: Wed Jun 24 22:00:02 2015 +0300 drm/i915: Split atomic wm update to pre and post variants -- the watermark stuff is Skylake-specific, so can't regress BSW/BDW. This has been tested on a number of SKL machines now, fixing the bug.
