From: Shirish S <shirish.s@xxxxxxx> Adding affected planes without checking if modeset is requested from the user space causes performance regression in video p/b scenarios when full screen p/b is not composited. Hence add a check before adding a plane as affected. bug: https://bugs.freedesktop.org/show_bug.cgi?id=103408 Signed-off-by: Shirish S <shirish.s at amd.com> --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index f0b50d9..e6ec130 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -4727,6 +4727,9 @@ static int amdgpu_dm_atomic_check(struct drm_device *dev, } } else { for_each_oldnew_crtc_in_state(state, crtc, old_crtc_state, new_crtc_state, i) { + if (!drm_atomic_crtc_needs_modeset(new_crtc_state)) + continue; + if (!new_crtc_state->enable) continue; -- 2.7.4
