From a0864d5905a94359621946a027e180a3063f80a5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 23 Mar 2017 21:27:09 +0200 Subject: [PATCH] drm/i915: Pre-compute plane control register value MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Computing the plane control register value is branchy so moving it out from the plane commit hook seems prudent. Let's pre-compute it during the atomic check phase and store the result in the plane state.
