This series has a few goals: - make timestamps more accurate by not using rounded pixel/line durations - avoid infinite loops in vblank code - use the timestamps to guesttimate the number of missed vblanks, in case there's no hardware frame counter, or it can't be trusted - fix bogus vblank counts/timstamps when the vblank counter incerements by an even number
Also available in my git repo (with a few hacks on top): git://github.com/vsyrjala/linux.git vblank_ts_diff_5
