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 Nicholas Piggin (7): 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 arch/powerpc/include/asm/cpuidle.h | 32 ++++- arch/powerpc/include/asm/exception-64s.h | 13 +- arch/powerpc/include/asm/reg.h | 1 + arch/powerpc/kernel/exceptions-64s.S | 123 +++++++---------- arch/powerpc/kernel/idle_book3s.S | 227 ++++++++++++++++++++++--------- arch/powerpc/platforms/powernv/idle.c | 13 -- 6 files changed, 242 insertions(+), 167 deletions(-) -- 2.11.0
