[PATCH 00/11] drm: vblank fixes and timestamp based missed vblank guesttimation

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

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

Ville Syrjälä (11):
  drm: s/int crtc/unsigned int pipe/ straggles
  drm: Move timestamping constants into drm_vblank_crtc
  drm: Stop using linedur_ns and pixeldur_ns for vblank timestamps
  drm: Kill pixeldur_ns
  drm/i915: Fix vblank count variable types
  drm: Pass flags to drm_update_vblank_count()
  drm: Limit the number of .get_vblank_counter() retries
  drm: Clean up drm_calc_vbltimestamp_from_scanoutpos() vbl_status
  drm: store_vblank() is never called with NULL timestamp
  drm: Use vblank timestamps to guesstimate how many vblanks were missed
  drm: Fix vblank timestamp races
