These patches implement enough to install a distro, boot, run SMP KVM
guests with libvirt with good performance using MTTCG (as reported by
Cedric).
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 1 LPAR mode. But those can
be added in time, it will take a bit of time to get everything exactly
as hardware does so I consider this good enough to run common
software usefully.
Since RFC:
- Rebased against ppc-next (no conflicts vs upstream anyway).
- Add patch 4 avocado boot test with SMT, as was added with pseries SMT.
- Renamed POWERPC_FLAG_1LPAR to POWERPC_FLAG_SMT_1LPAR since it implies
SMT.
- Fixed typos, patch 1, 3 changelogs improvement (hopefully).
Since v1:
- Fix clang compile bug
- Fix LPAR-per-thread bug in CTRL/DPDES/msgsndp in patch 1
- Add 2-socket test case to powernv Linux boot avocado test
- Remove SMT caveat from docs/system/ppc/powernv.rst
Thanks,
Nick
