From 2afa701d3e0bb9865130990b5e0cfe240ae3b605 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 15 Oct 2015 20:40:02 +0300 Subject: [PATCH] drm: Check plane src coordinates correctly during page flip for atomic drivers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of relying on the old crtc-{x,y,mode} gunk, dig out the primary plane coordinates from the plane state when checking them against the new framebuffer during page flip.
