[v3,0/6] KVM: selftests: add powerpc support

Message

Nicholas Piggin June 8, 2023, 3:24 a.m. UTC

This series adds initial KVM selftests support for powerpc
(64-bit, BookS, radix MMU).

Since v2:
- Added a couple of new tests (patch 5,6)
- Make default page size match host page size.
- Check for radix MMU capability.
- Build a few more of the generic tests.

Since v1:
- Update MAINTAINERS KVM PPC entry to include kvm selftests.
- Fixes and cleanups from Sean's review including new patch 1.
- Add 4K guest page support requiring new patch 2.

Thanks,
Nick
