[PATCH 1/2] drm/nouveau: Use drm_vblank_count_and_time() for pageflip completion events.
From: Mario Kleiner <mario.kleiner at tuebingen.mpg.de>
Emit kms pageflip completion events with proper vblank count
and timestamp for the vblank interval in which the pageflip
completed. This makes the timestamps and counts consistent with
what the OML_sync_control spec defines.
v2 Lucas Stach: rebased on top of nouveau tree and resolved trivial
conflict.

[Patches][nouveau/kms]: Precise Vblank and pageflip timestamping
Hi,
these are two patches against the nouveau kms driver. The first patch
makes sure that pageflip completion events get their vblank count and
timestamp from the drm. The second patch from Lucas Stach, here included
with his permission, makes sure that the timestamps of vblanks are
calculated with high precision and robustness. Both patches together
make sure that all timestamps returned by the

[Patches][nouveau/kms]: Precise Vblank and pageflip timestamping v2
Just updated versions of the patches send by Mario Kleiner. This ones are
rebased on top of the nouveau tree and updated according to the review
feedback.

[PATCH v2 00/21] drm: Clean up VBLANK callbacks in struct drm_driver
VBLANK handlers in struct drm_driver are deprecated. Only legacy,
non-KMS drivers are supposed to used them. DRM drivers with kernel
modesetting are supposed to use VBLANK callbacks of the CRTC
infrastructure.
This patchset converts all DRM drivers to CRTC VBLANK callbacks and
cleans up struct drm_driver. The remaining VBLANK callbacks in struct
drm_driver are only used by legacy drivers.
