It has also been updated so as to not disable EC=ESL=0 idle states for CPU unplug. That case (and powersave=off) continues to be broken for KVM with unplugged dependent secondaries, but that's another issue. This also has EC=ESL=0 states to skip the new hwsync added for the KVM workaround, which should increase their performance advantage a little further. Thanks, Nick Nicholas Piggin (3): powerpc/64s/idle: POWER9 implement a separate idle stop function for hotplug powerpc/64s/idle: avoid sync for KVM state when waking from idle powerpc/64s/idle: POWER9 ESL=0 stop avoid save/restore overhead arch/powerpc/include/asm/processor.h | 1 + arch/powerpc/kernel/idle_book3s.S | 69 +++++++++++++++++------------------ arch/powerpc/platforms/powernv/idle.c | 2 +- 3 files changed, 36 insertions(+), 36 deletions(-) -- 2.16.3
