17:18 Tom^: is DRM_EVENT_CRTC_SEQUENCE sent earlier then the pageflip or is it just a more controllable event compared to the pageflip where i can queue for a specific sequence and also get a more accurate timestamp?
17:30 Tom^: what made me questioning this is because i see "Event delivered at sequence. Time stamp marks when the first pixel of the refresh cycle leaves the display engine for the display" in uapi drm.h , but the timestamps are the same in both pageflip and this sequence when testing. besides pageflip timestamp being rounded off a bit.
17:30 Tom^: so in short, does the event also trigger at first pixel of refresh cycle, and pageflip is when its all done? or are they generally the same?
