I tried it and it is not as good as Andrew Morton's low
latency patch in terms of latency. It does essentially the
same thing (in the context of the preemptible kernel patch)
but does not fix as many high latency points as Andrews', or
so I think. I'm currently running a mix of the preemptible
kernel patch (without the lock break) and Andrew's low latency
patch (but the low latency patch alone is enough).
I did find some problems with the dri interface and found a
patch inside Jussi Laako's patchset (jussi.laako_AT_kolumbus.fi)
that fixed it (I was testing with latencytest 0.42). See:
