From: Ville Syrjälä Date: Wed, 24 Jun 2015 19:00:02 +0000 (+0300) Subject: drm/i915: Split atomic wm update to pre and post variants X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f015c5518879fb3e578caaa63806617468a24045;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Split atomic wm update to pre and post variants Try to update the watermarks on the right side of the plane update. This is just a temporary hack until we get the proper two part update into place. However in the meantime this might have some chance of at least working.
