817 Drivers that do per-buffer uploads, need a buffer damage handling (rather than
818 frame damage like drivers that do per-plane or per-CRTC uploads), but there is
819 no support to get the buffer age or any other damage accumulation algorithm.
821 For this reason, the damage helpers just fallback to a full plane update if the
825 helpers that the damage clips should be ignored.
