This temporarily reverts freesync video patches since it causes regression with eDP displays. This patch is a squashed revert of the following patches: a372f4abecb1 drm/amd/display: Skip modeset for front porch change 952bc47fb2ca drm/amd/display: Add freesync video modes based on preferred modes d03ee581eee6 drm/amd/display: Add module parameter for freesync video mode Signed-off-by: Aurabindo Pillai <aurabindo.pillai at amd.com> --- drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 - drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 12 - .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 369 ++---------------- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h | 2 - 4 files changed, 35 insertions(+), 349 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu.h b/drivers/gpu/drm/amd/amdgpu/amdgpu.h index 67279a40ab2c..a6b9b6aa5cd1 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu.h @@ -185,7 +185,6 @@ extern int amdgpu_emu_mode;
