Hi All, This series primarly adds KVM selftests support for powerpc (64-bit, BookS, radix MMU). This patch series is originally Nick's work. I have mainly only rebased it on the latest upstream tree. Since the rebase required few changes to all the four patches (Patch 1-4), I have dropped the earlier Acked-by from Michael Ellerman. Since the last series was posted three years ago [1], I am resetting the version to RFC. This rebase was done as part of a larger effort to improve the selftests infrastructure for Linux on PowerPC tree. Thanks to Harsh and Maddy for their help on this. Testing Updates: ================ 1. Tested this on PowerNV P9 with Radix mode. (all selftests passes) 2. Tested this on LPAR (KVM on PowerVM) case. (all selftests except-1 passes). The failed testcase (kvm_create_max_vcpus) is because H_GUEST_CREATE_VCPU (PAPR HCALL) only supports vcpu_ids 0-2047 i.e. max 2048 vcpus. However, kernel always returns NR_CPUS for the KVM_CAP_MAX_VCPUS extension. So if the LPAR kernel is built using NR_CPUS=8192, then kvm_create_max_vcpus can fail in __vm_vcpu_add(). This failure needs to be handled separately, mostly as fix in kernel. 3. Tested these selftests changes inside x86 kvm guest - no new failures seen. RFCv2 -> RFC v3: =============== 1. Relaxed strict pte permission checking in patch-3 (Sashiko) 2. Fixed errno from getting clobbered in patch-5 (Sashiko) 3. Added PATCH 6-9 to handle the type conversion (e.g. uint64_t to u64) as was done earlier with other kvm selftests. Kept these patches separate to keep the review & changelog simpler. 4. Added PATCH 10, which replaces u64 gpa/gva to use gpa_t and gva_t and converts the vaddr variable to gva as done by some previous commits for other kvm selftests. Kept this patch separate to keep the review & changelog simpler. RFC v1 -> RFC v2 ================ (mostly Sashiko review comments) 1. Fixed x86's stage-2 mmu handling in patch-1 - commit msg has more description 2. Added "cc" into the clobber list for hcalls in patch-3 3. Fixed the size calculation in kvm_arch_vm_post_create in patch-3 for allocating 2 pages for 4K pagesize 4. Added patch-5 which prints vcpu_id in case of an error [RFCv2]: https://lore.kernel.org/all/cover.1779524962.git.ritesh.list@gmail.com/ [RFCv1]: https://lore.kernel.org/linuxppc-dev/cover.1778857539.git.ritesh.list@gmail.com/ [1]: https://lore.kernel.org/all/20231120122920.293076-1-npiggin@gmail.com/ Nicholas Piggin (4): KVM: selftests: Move pgd_created check into virt_pgd_alloc KVM: selftests: Add aligned guest physical page allocator KVM: PPC: selftests: add support for powerpc KVM: PPC: selftests: powerpc enable kvm_create_max_vcpus test Ritesh Harjani (IBM) (6): KVM: selftests: Print the vcpu_id when KVM_CREATE_VCPU ioctl fails KVM: PPC: selftests: Use u64 instead of uint64_t KVM: PPC: selftests: Use s64 instead of int64_t KVM: PPC: selftests: Use u32 instead of uint32_t KVM: PPC: selftests: Use u8 instead of uint8_t KVM: PPC: selftests: Replace u64 gpa, u64 gva|vaddr with gpa_t and gva_t MAINTAINERS | 2 + tools/testing/selftests/kvm/Makefile | 2 +- tools/testing/selftests/kvm/Makefile.kvm | 10 + .../testing/selftests/kvm/include/kvm_util.h | 34 +- .../selftests/kvm/include/powerpc/hcall.h | 17 + .../kvm/include/powerpc/kvm_util_arch.h | 22 + .../selftests/kvm/include/powerpc/ppc_asm.h | 32 ++ .../selftests/kvm/include/powerpc/processor.h | 39 ++ .../selftests/kvm/include/powerpc/ucall.h | 21 + .../selftests/kvm/kvm_create_max_vcpus.c | 9 + .../selftests/kvm/lib/arm64/processor.c | 4 - tools/testing/selftests/kvm/lib/guest_modes.c | 20 +- tools/testing/selftests/kvm/lib/kvm_util.c | 48 +- .../selftests/kvm/lib/loongarch/processor.c | 4 - .../selftests/kvm/lib/powerpc/handlers.S | 93 ++++ .../testing/selftests/kvm/lib/powerpc/hcall.c | 45 ++ .../selftests/kvm/lib/powerpc/processor.c | 483 ++++++++++++++++++ .../testing/selftests/kvm/lib/powerpc/ucall.c | 22 + .../selftests/kvm/lib/riscv/processor.c | 4 - .../selftests/kvm/lib/s390/processor.c | 4 - 20 files changed, 876 insertions(+), 39 deletions(-) create mode 100644 tools/testing/selftests/kvm/include/powerpc/hcall.h create mode 100644 tools/testing/selftests/kvm/include/powerpc/kvm_util_arch.h create mode 100644 tools/testing/selftests/kvm/include/powerpc/ppc_asm.h create mode 100644 tools/testing/selftests/kvm/include/powerpc/processor.h create mode 100644 tools/testing/selftests/kvm/include/powerpc/ucall.h create mode 100644 tools/testing/selftests/kvm/lib/powerpc/handlers.S create mode 100644 tools/testing/selftests/kvm/lib/powerpc/hcall.c create mode 100644 tools/testing/selftests/kvm/lib/powerpc/processor.c create mode 100644 tools/testing/selftests/kvm/lib/powerpc/ucall.c -- 2.50.1 (Apple Git-155)
