Subject: [RFC][PATCH 0/2] process interrupts from idle wakeup
Date: Tue, 21 Mar 2017 14:52:52 +1000 [thread overview]
Message-ID: <20170321045254.21384-1-npiggin@gmail.com> (raw)
Hi,
Just wanted to get some opinions on this approach. I will wait until
current batch of idle fixes are merged before submitting properly,
and still need to test on POWER9, but on POWER8 the speedup is
quite good.
Thanks,
Nick
