From 693bdc28a733dba68b86af295e7509812fec35d9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 15 Jan 2016 20:46:53 +0200 Subject: [PATCH] drm/i915: Don't reject primary plane windowing with color keying enabled on SKL+ MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On SKL+ plane scaling is mutually exclusive with color keying. The code check for this, but during some refactoring the code got changed to also reject primary plane windowing when color keying is used. There is no such restriction in the hardware, so restore the original logic. Cc: Maarten Lankhorst Fixes: 061e4b8d650a ("drm/i915: clean up atomic plane check functions, v2.")
