Certainly, it's a finite value...
However, realistically, it's just like all of the other vblank
interfaces where you can specify a crazy sequence and block for a very
long time. So, no different from the
crtc_queue_syncobj creates a new syncobj that will get signaled at a
specified vblank sequence count.
crtc_get_syncobj returns the time and vblank sequence count when the
syncobj was signaled.
The pair of these allows use of syncobjs instead of events for
monitoring vblank activity.
