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 v4: draw_area -> pipe_src Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5440 Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Jouni Högander <jouni.hogander@intel.com> --- drivers/gpu/drm/i915/display/intel_psr.c | 23 ++++++++++++++++------- 1 file changed, 16 insertions(+), 7 deletions(-)
