Subject: [RFC PATCH 0/3] ppc/pnv: SMT support for powernv
Date: Thu, 29 Jun 2023 12:16:30 +1000	[thread overview]
Message-ID: <20230629021633.328916-1-npiggin@gmail.com> (raw)

These patches implement enough to boot a SMT powernv machine to Linux
and boot a SMP KVM guest inside that.

There are a few more SPRs that need to be done, and per-LPAR SPRs are
mostly not annotated yet so it can't run in 1LPAR mode. But it is
enough to run skiboot/Linux with SMT so I'll just post the minimal
patches for RFC because the concept isn't really different to add
more SPRs and things.

Thanks,
Nick
