Date: Wed, 7 Mar 2018 19:41:52 +0000 [thread overview]
Message-ID: <20180307194202.31099-1-chris@chris-wilson.co.uk> (raw)
While we continue to observe hangs even with this w/a in place, I do
believe we are in a better position (although that may just be my
confirmation bias). I certainly don't think it's all happy yet. Mika
believes that if we keep the cpu in C0 whilst the gpu is busy, then it
behaves much better -- but that is a very tough sell; virtually disabling
cpu powersaving entirely, for the gpu rarely sleeps under the target
workloads.
Still I think this series moves us forwards and would appreciation acks
or an outright nak to drop it. :)
