With the DRM-driven DPMS code, encoders are considered idle unless a

By sending a broken execbuffer (its length was not suitably aligned) I
triggered an operation upon a freed object. The invalid alignment was
discovered after updating the write_domain on the object but before the
object was placed on the active queue. So during the unwind process
following the error, the now freed object attempts to flush its
non-existent, but outstanding, GPU writes causing this use-after-free.

We will get the info of SDVO device by parsing the general definition blocks.
Only when a valid slave address is found, it is regarded as the SDVO device.
And the info of DVO port and slave address is recorded.

keithp didn't like the original 20ms plan because a cooperative client could
be starved by an uncooperative client.  There may even have been problems
with cooperative clients versus cooperative clients.  So keithp changed
throttle to just wait for the second to last seqno emitted by that client.
It worked well, until we started getting more round-trips to the server
due to DRI2 -- the server throttles in BlockHandler, and so if you did more
than one round trip after finishing your frame, you'd end up unintentionally
syncing to the swap.

Fix this by keeping track of the client's requests, so the client can wait
when it has an outstanding request over 20ms old.  This should have
non-starving behavior, good behavior in the presence of restarts, and less
waiting.  Improves high-settings openarena performance on my GM45 by 50%.

Since the other object doesn't rely on the fence reg for its execution, we
