Selective fetch only supports one region to be fetched so software needs to calculate a bounding box around all damage clips. Now that we are not complete fetching each plane, there is another loop needed as all the plane areas that intersect with the pipe damadged area needs to be fetched from memory so the complete blending of all planes can happen. v2: - do not shifthing new_plane_state->uapi.dst only src is in 16.16 format v4: - setting plane selective fetch area using the whole pipe damage area - mark the whole plane area damaged if plane visibility or alpha changed v5: - taking in consideration src.y1 in the damage coordinates - adding to the pipe damaged area planes that were visible but are invisible in the new state Cc: Ville Syrjälä Cc: Gwan-gyeong Mun Signed-off-by: José Roberto de Souza --- drivers/gpu/drm/i915/display/intel_psr.c | 93 ++++++++++++++++++++---- 1 file changed, 79 insertions(+), 14 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_psr.c b/drivers/gpu/drm/i915/display/intel_psr.c index d9a395c486d3..b256184821da 100644 --- a/drivers/gpu/drm/i915/display/intel_psr.c +++ b/drivers/gpu/drm/i915/display/intel_psr.c @@ -1269,11 +1269,11 @@ int intel_psr2_sel_fetch_update(struct intel_atomic_state *state, struct intel_crtc *crtc) { struct intel_crtc_state *crtc_state = intel_atomic_get_new_crtc_state(state, crtc);
