Subject: [PATCH v2 0/4] powerpc: stolen time accounting for VIRT_CPU_ACCOUNTING_GEN
Date: Fri, 2 Sep 2022 18:53:12 +1000 [thread overview]
Message-ID: <20220902085316.2071519-1-npiggin@gmail.com> (raw)
pseries provides stolen time accounting when VIRT_CPU_ACCOUNTING_NATIVE
is selected, but not when VIRT_CPU_ACCOUNTING_GEN is. We like GEN
because it's less code in arch/powerpc, allows full nohz, and distros
have moved to it, so this series adds stolen time accounting for GEN,
and moves our pseries configs over to it.
Thanks,
Nick
Since v1:
- Move the KVM patches out of this series to make it smaller.
I'll post them separately.
- Fix compilation bug in patch 2 due to missing header in patch.
- Add defconfig changes to patch 3.
- Add tidy up patch 4.
- Improve changelogs.

lppaca
powerpc/pseries: Implement CONFIG_PARAVIRT_TIME_ACCOUNTING
powerpc/64: Remove PPC64 special case for cputime accounting default
powerpc/pseries: Move dtl scanning and steal time accounting to
pseries platform
