This series adds initial KVM selftests support for powerpc (64-bit, BookS, radix MMU). Since v3: https://lore.kernel.org/linuxppc-dev/20230608032425.59796-1-npiggin@xxxxxxxxx/ - Rebased to upstream (on top of Sean's ucall and guest assert rework). - Drop powerpc specific tests for now, concentrate on base enablement. - Fix a bunch of bugs and issues including the ones noticed by Joel in v3: - Work around powerpc's max VCPU ID complexity to fix test case failure. - Use TEST_REQUIRE for radix mode so hash hosts don't assert. - Pack page table "fragments" in pages (like Linux kernel does), which fixes PTE memory consumption estimation and prevents the max memory test from failing with no memory for page tables. 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.
