Patch 1-7 re-structured the get-reg-list test in aarch64 to make some of the code as common test framework that can be shared by riscv. Patch 8 enabled the KVM_GET_REG_LIST API in riscv and patch 9-11 added the corresponding kselftest for checking possible register regressions. The get-reg-list kvm selftest was ported from aarch64 and tested with Linux 6.4-rc1 on a Qemu riscv virt machine. --- Changed since v1: * rebase to Andrew's changes * fix coding style Andrew Jones (7): KVM: arm64: selftests: Replace str_with_index with strdup_printf KVM: arm64: selftests: Drop SVE cap check in print_reg KVM: arm64: selftests: Remove print_reg's dependency on vcpu_config KVM: arm64: selftests: Rename vcpu_config and add to kvm_util.h KVM: arm64: selftests: Delete core_reg_fixup KVM: arm64: selftests: Split get-reg-list test code KVM: arm64: selftests: Finish generalizing get-reg-list Haibo Xu (4): KVM: riscv: Add KVM_GET_REG_LIST API support KVM: riscv: selftests: Make check_supported arch specific KVM: riscv: selftests: Skip some registers set operation KVM: riscv: selftests: Add get-reg-list test Documentation/virt/kvm/api.rst | 2 +- arch/riscv/kvm/vcpu.c | 372 ++++++++++++ tools/testing/selftests/kvm/Makefile | 13 +- .../selftests/kvm/aarch64/get-reg-list.c | 540 ++---------------- tools/testing/selftests/kvm/get-reg-list.c | 426 ++++++++++++++ .../selftests/kvm/include/kvm_util_base.h | 16 + .../selftests/kvm/include/riscv/processor.h | 3 + .../testing/selftests/kvm/include/test_util.h | 2 + tools/testing/selftests/kvm/lib/test_util.c | 15 + .../selftests/kvm/riscv/get-reg-list.c | 539 +++++++++++++++++ 10 files changed, 1428 insertions(+), 500 deletions(-) create mode 100644 tools/testing/selftests/kvm/get-reg-list.c create mode 100644 tools/testing/selftests/kvm/riscv/get-reg-list.c
