Proper fix I think needs the following bits: - address the FIXME in intel_atomic_commit_tail about when commit_hw_done() should be called. We need to make sure that this is before any of the expensive vblank waits, which needs the separate worker as described in the comments. - in wait_for_depencies don't stall for flip_done for legacy cursor updates This essentially gets us halfway there to faster-than-vrefresh updates. The other bits needed would just be the correct flip_done signalling, and switching the wait_for_vblank (before cleanup_planes) over to wait_for_flip. Typing this down since I'm going on vacation soon and probably won't be able to fix this all up.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
