Subject: [PATCH 0/7][v3] idle fixes and changes for POWER8 and POWER9
Date: Mon, 20 Mar 2017 16:01:45 +1000 [thread overview]
Message-ID: <20170320060152.1016-1-npiggin@gmail.com> (raw)
Since last time:
- Commented machine check handler wakeup to describe why registers are
not lost.
- Dropped patch to make PACA_THREAD_IDLE_STATE POWER8-only because
Gautham will use it for POWER9 DD1.
- Removed some leftover debug cruft noticed by Gautham, and re-tested
on POWER8. Added some extra comments to hopefully try to illustrate
the idle state changes a bit better.
Needs:
- Ack from Gautham for patch 7
- Ack from Mahesh for patch 4
Thanks,
Nick
