Subject: [PATCH] powerpc/64: Remove PPC64 special case for cputime accounting default
Date: Wed, 25 May 2022 18:13:46 +1000	[thread overview]
Message-ID: <20220525081346.871535-1-npiggin@gmail.com> (raw)

Distro kernels tend to be moving to VIRT_CPU_ACCOUNTING_GEN, and there
is not much reason why PPC64 should be special here.

VIRT_CPU_ACCOUNTING_NATIVE does provide scaled vtime and stolen time
apportioned between system and user time, and vtime accounting is not
unconditionally enabled, and possibly other things. But it would be
better at this point to extend GEN to cover important missing features
rather than directing users back to a less used option.

After implementing stolen time for GEN for powerpc, can we try this and
see who screams?

Thanks,
Nick
