From: Ville Syrjälä Date: Fri, 7 Mar 2014 16:32:13 +0000 (+0200) Subject: drm/i915: Disable/enable planes as the first/last thing during modeset on ILK+ X-Git-Tag: next-20140428~44^2~43 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a5c4d7bc187bd13bc11ac06bb4ea3a0d4001aa4d;p=karo-tx-linux.git drm/i915: Disable/enable planes as the first/last thing during modeset on ILK+ We already do this for HSW, but doing it makes sense for everything else as well. Extend it for ILK/SNB/IVB since that's where the new watermark code is used.
