Subject: [PATCH v2 0/9] idle fixes and changes for POWER8 and POWER9
Date: Wed, 19 Apr 2017 23:05:42 +1000 [thread overview]
Message-ID: <20170419130551.32378-1-npiggin@gmail.com> (raw)
Since last posting:
- accounted for some minor omments
- improved changelogs
- updated to powerpc next which includes Gautham's idle changes.
- Fixed CONFIG_RELOCATABLE build with the new patch 1.
- Also added the last patch which simplifies the DD1 workaround,
which is possible with HSPRG0 wakeup differences removed.
Nicholas Piggin (9):
powerpc/64s: Remove unnecessary relocation branch from idle handler
powerpc/64s: move remaining system reset idle code into idle_book3s.S
powerpc/64s: stop using bit in HSPRG0 to test winkle
powerpc/64s: use alternative feature patching
powerpc/64s: fix POWER9 machine check handler from stop state
powerpc/64s: idle expand core idle state bits
powerpc/64s: idle do not hold reservation longer than required
powerpc/64s: idle POWER8 avoid full state loss recovery where possible
powerpc/64s: Simplify POWER9 DD1 idle workaround code
