VBlank event handling
The DRM core exposes two vertical blank related ioctls:
- DRM_IOCTL_WAIT_VBLANK and DRM_IOCTL_MODESET_CTL.
+
+
+ DRM_IOCTL_WAIT_VBLANK
+
+
+ This takes a struct drm_wait_vblank structure as its argument,
+ and it is used to block or request a signal when a specified
+ vblank event occurs.
+
+
+
+
+ DRM_IOCTL_MODESET_CTL
+
+
+ This should be called by application level drivers before and
+ after mode setting, since on many devices the vertical blank
+ counter is reset at that time. Internally, the DRM snapshots
+ the last vblank count when the ioctl is called with the
+ _DRM_PRE_MODESET command so that the counter won't go backwards
+ (which is dealt with when _DRM_POST_MODESET is used).
+

To support the functions above, the DRM core provides several
helper functions for tracking vertical blank counters, and
