Changelog ========= v4: * Removed the patch to precompute cpu type, will be introduced as part of a separate series in future. v3: * Original series is split into two and this v3 version contains the improvements to selftest and VM setup. * Planning to upload the second series to execute hypercall instruction according to cpu type separately. * Addressed comments from David and Sean. link to v3: https://lore.kernel.org/lkml/20221013121319.994170-1-vannapurve@google.com/ v2: * Addressed comments from Andrew and David * Common function with constructor attribute used to setup initial state * Changes are split in more logical granules as per feedback link to v2: https://lore.kernel.org/all/20220915000448.1674802-1-vannapurve@google.com/ Vishal Annapurve (3): KVM: selftests: move common startup logic to kvm_util.c KVM: selftests: Add arch specific initialization KVM: selftests: Add arch specific post vm creation hook .../selftests/kvm/aarch64/arch_timer.c | 3 --- .../selftests/kvm/aarch64/hypercalls.c | 2 -- .../testing/selftests/kvm/aarch64/vgic_irq.c | 3 --- .../selftests/kvm/include/kvm_util_base.h | 9 ++++++++ .../selftests/kvm/lib/aarch64/processor.c | 18 ++++++++-------- tools/testing/selftests/kvm/lib/kvm_util.c | 21 ++++++++++++++++--- .../selftests/kvm/lib/x86_64/processor.c | 6 ++++++ .../testing/selftests/kvm/memslot_perf_test.c | 3 --- tools/testing/selftests/kvm/rseq_test.c | 3 --- tools/testing/selftests/kvm/s390x/memop.c | 2 -- tools/testing/selftests/kvm/s390x/resets.c | 2 -- .../selftests/kvm/s390x/sync_regs_test.c | 3 --- .../selftests/kvm/set_memory_region_test.c | 3 --- .../kvm/x86_64/cr4_cpuid_sync_test.c | 3 --- .../kvm/x86_64/emulator_error_test.c | 3 --- .../selftests/kvm/x86_64/hyperv_cpuid.c | 3 --- .../selftests/kvm/x86_64/platform_info_test.c | 3 --- .../kvm/x86_64/pmu_event_filter_test.c | 3 --- .../selftests/kvm/x86_64/set_sregs_test.c | 3 --- .../kvm/x86_64/svm_nested_soft_inject_test.c | 3 --- .../selftests/kvm/x86_64/sync_regs_test.c | 3 --- .../selftests/kvm/x86_64/userspace_io_test.c | 3 --- .../kvm/x86_64/userspace_msr_exit_test.c | 3 --- 23 files changed, 42 insertions(+), 66 deletions(-)
