Yes, patch is sane, I'm just messing around with my Braswell at the
moment and then I'll try again at getting some numbers. First glance
said 10% in reducing latency (with a 100% throughput improvement in one
particular small copy scenario, that I want to reprdouce and do some back
of the envelope calculations to check that it is sane), but the machine
(thanks to execlists) just dies as soon as I try some more interesting
benchmarks.
