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

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. Signed-off-by: Mario Kleiner

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. Regards, Lucas

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. Patch
