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 v3: Move drm_rect_intersect into clip_area_update Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5440 Cc: José Roberto de Souza <jose.so...@intel.com> Cc: Mika Kahola <mika.kah...@intel.com> Cc: Mark Pearson <markpear...@lenovo.com> Signed-off-by: Jouni Högander <jouni.hogan...@intel.com> --- drivers/gpu/drm/i915/display/intel_psr.c | 24 +++++++++++++++++------- 1 file changed, 17 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_psr.c b/drivers/gpu/drm/i915/display/intel_psr.c index 3561c218cfb1..f4b4c1c83d2b 100644 --- a/drivers/gpu/drm/i915/display/intel_psr.c +++ b/drivers/gpu/drm/i915/display/intel_psr.c @@ -1618,8 +1618,12 @@ static void psr2_man_trk_ctl_calc(struct intel_crtc_state *crtc_state, } static void clip_area_update(struct drm_rect *overlap_damage_area, - struct drm_rect *damage_area) + struct drm_rect *damage_area, + struct drm_rect *draw_area) { + if (!drm_rect_intersect(damage_area, draw_area)) + return; + if (overlap_damage_area->y1 == -1) { overlap_damage_area->y1 = damage_area->y1; overlap_damage_area->y2 = damage_area->y2; @@ -1709,7 +1713,8 @@ 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 }; + struct drm_rect src, damaged_area = { .x1 = 0, .y1 = -1, + .x2 = INT_MAX }; struct drm_atomic_helper_damage_iter iter; struct drm_rect clip; @@ -1736,20 +1741,23 @@ 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); + clip_area_update(&pipe_clip, &damaged_area, + &crtc_state->pipe_src); } 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); + clip_area_update(&pipe_clip, &damaged_area, + &crtc_state->pipe_src); } 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); + clip_area_update(&pipe_clip, &damaged_area, + &crtc_state->pipe_src); continue; } @@ -1760,7 +1768,8 @@ int intel_psr2_sel_fetch_update(struct intel_atomic_state *state, &new_plane_state->uapi); drm_atomic_for_each_plane_damage(&iter, &clip) { if (drm_rect_intersect(&clip, &src)) - clip_area_update(&damaged_area, &clip); + clip_area_update(&damaged_area, &clip, + &crtc_state->pipe_src); } if (damaged_area.y1 == -1) @@ -1768,7 +1777,8 @@ 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); + + clip_area_update(&pipe_clip, &damaged_area, &crtc_state->pipe_src); } /* -- 2.25.1
