This is a note to let you know that I have just added a patch titled drm/radeon/atom: fix dithering on certain panels to the linux-3.11.y-queue branch of the 3.11.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.11.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.11.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From e68e91a9910ef708dc659c1dec0e5fd9c9868e1f Mon Sep 17 00:00:00 2001 From: Alex Deucher <alexander.deucher@amd.com> Date: Tue, 27 May 2014 16:40:51 -0400 Subject: drm/radeon/atom: fix dithering on certain panels commit 642528355c694f5ed68f6bff9ff520326a249f99 upstream. We need to specify the encoder mode as LVDS for eDP when using the Crtc_Source atom table in order to properly set up the FMT hardware. bug: https://bugs.freedesktop.org/show_bug.cgi?id=73911 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Luis Henriques <luis.henriques@canonical.com> --- drivers/gpu/drm/radeon/atombios_encoders.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) -- 1.9.1
