This is needed to make applications depending on vblank/page flip
timestamps independent of time ajdustments.
I've tested these with an updated intel-gpu-test/flip_test and will send
the update for that once there's no objection about this patchset.
The patchset is based on danvet's dinq branch with the following
additional patches from the intel-gfx ML applied:
drm/i915: paper over a pipe-enable vs pageflip race
drm/i915: don't frob the vblank ts in finish_page_flip
drm/i915: call drm_handle_vblank before finish_page_flip
Imre Deak (4):
time: export getnstime_raw_and_real for DRM
drm: make memset/calloc for _vblank_time more robust
drm: use raw time in drm_calc_vbltimestamp_from_scanoutpos
drm: add support for raw monotonic vblank timestamps
