From: Rob Clark <[email protected]>
Until various PM devfreq/QoS and interconnect patches land, we could
potentially trigger reclaim from gpu scheduler thread, and under enough
memory pressure that could trigger a sort of deadlock. Eventually the
wait will timeout and we'll move on to consider other GEM objects. But
given that there is still a potential for deadlock/stalling, we should
reduce the timeout to contain the damage.
