* the update is completed, as signalled through the vblank event's timestamp
* (see struct drm_event_vblank).
*
* This flag must be set when the KMS update might cause visible artifacts.
* Without this flag such KMS update will return a EINVAL error. What kind of
* update may cause visible artifacts depends on the driver and the hardware.
* User-space that needs to know beforehand if an update might cause visible
* artifacts can use &DRM_MODE_ATOMIC_TEST_ONLY without
* &DRM_MODE_ATOMIC_ALLOW_MODESET to see if it fails.
*
* To the best of the driver's knowledge, visual artifacts are guaranteed to
* not appear when this flag is not set. Some sinks might display visual
* artifacts outside of the driver's control.
