The overlay planes +exposed by amdgpu_dm were therefore being rendered as invisible by +default ever since supported was exposed for alpha blending properties +on overlays. + +This caused regressions in igt@kms_plane_multiple@atomic-tiling-none +and igt@kms_plane@plane-position-covered-pipe tests. + +[How] +Reset the plane state values to their correct values as defined in +the drm helper. + +This fixes the IGT test regression. + +Change-Id: I4ebfad24456f8a898cd36394e769a0d216549e92 +Signed-off-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> +Reviewed-by: Harry Wentland <Harry.Wentland@amd.com> +Acked-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> +--- + drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 2 ++ + 1 file changed, 2 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 b071b41fdc8a..3949d932e648 100644 +--- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c ++++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +@@ -3781,6 +3781,8 @@ static void dm_drm_plane_reset(struct drm_plane *plane) + plane->state = &amdgpu_state->base; + plane->state->plane = plane; + plane->state->rotation = DRM_MODE_ROTATE_0; ++ plane->state->alpha = DRM_BLEND_ALPHA_OPAQUE; ++ plane->state->pixel_blend_mode = DRM_MODE_BLEND_PREMULTI; + } + } + +-- +2.17.1 + |
