From 83926117273cd6d9ffa1b5ff0cc566ad38648b70 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 16 Nov 2015 17:02:34 +0200 Subject: [PATCH] drm: Fix primary plane size for stereo doubled modes for legacy setcrtc MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Properly double the hdisplay/vdisplay timings that we use as the primary plane size with stereo doubled modes. Otherwise the modeset gets rejected on machines where the primary plane must be fullscreen, and on the rest only the first eye would get a visible plane.
