Current update area calculation is not handling situation where e.g. cursor plane is fully or partially outside pipe area.
Fix this by checking damage area against pipe_src area using drm_rect_intersect. v2: Set x1 and x2 in damaged_area initialization Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5440 Cc: José Roberto de Souza <[email protected]> Cc: Mika Kahola <[email protected]> Tested-by: Mark Pearson <[email protected]> Signed-off-by: Jouni Högander <[email protected]> --- drivers/gpu/drm/i915/display/intel_psr.c | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_psr.c b/drivers/gpu/drm/i915/display/intel_psr.c index 8c099d24de86..ecd062a0fea4 100644 --- a/drivers/gpu/drm/i915/display/intel_psr.c +++ b/drivers/gpu/drm/i915/display/intel_psr.c @@ -1708,7 +1708,9 @@ int intel_psr2_sel_fetch_update(struct intel_atomic_state *state, */ for_each_oldnew_intel_plane_in_state(state, plane, old_plane_state, new_plane_state, i) { - struct drm_rect src, damaged_area = { .y1 = -1 }; + /* Set damaged_area x1 and x2 for drm_rect_intersect usage */ + struct drm_rect src, damaged_area = { .x1 = 0, .y1 = -1, + .x2 = INT_MAX }; struct drm_atomic_helper_damage_iter iter; struct drm_rect clip; @@ -1735,20 +1737,23 @@ int intel_psr2_sel_fetch_update(struct intel_atomic_state *state, if (old_plane_state->uapi.visible) { damaged_area.y1 = old_plane_state->uapi.dst.y1; damaged_area.y2 = old_plane_state->uapi.dst.y2; - clip_area_update(&pipe_clip, &damaged_area); + if (drm_rect_intersect(&damaged_area, &crtc_state->pipe_src)) + clip_area_update(&pipe_clip, &damaged_area); } if (new_plane_state->uapi.visible) { damaged_area.y1 = new_plane_state->uapi.dst.y1; damaged_area.y2 = new_plane_state->uapi.dst.y2; - clip_area_update(&pipe_clip, &damaged_area); + if (drm_rect_intersect(&damaged_area, &crtc_state->pipe_src)) + clip_area_update(&pipe_clip, &damaged_area); } continue; } else if (new_plane_state->uapi.alpha != old_plane_state->uapi.alpha) { /* If alpha changed mark the whole plane area as damaged */ damaged_area.y1 = new_plane_state->uapi.dst.y1; damaged_area.y2 = new_plane_state->uapi.dst.y2; - clip_area_update(&pipe_clip, &damaged_area); + if (drm_rect_intersect(&damaged_area, &crtc_state->pipe_src)) + clip_area_update(&pipe_clip, &damaged_area); continue; } @@ -1767,7 +1772,9 @@ int intel_psr2_sel_fetch_update(struct intel_atomic_state *state, damaged_area.y1 += new_plane_state->uapi.dst.y1 - src.y1; damaged_area.y2 += new_plane_state->uapi.dst.y1 - src.y1; - clip_area_update(&pipe_clip, &damaged_area); + + if (drm_rect_intersect(&damaged_area, &crtc_state->pipe_src)) + clip_area_update(&pipe_clip, &damaged_area); } if (pipe_clip.y1 == -1) -- 2.25.1
