Hi, This patch series introduces two tests to further enhance and verify the functionality of the KVM subsystem. These tests focus on MSR_IA32_DS_AREA and MSR_IA32_PERF_CAPABILITIES. The first patch adds tests to verify the correct behavior when trying to set MSR_IA32_DS_AREA with a non-classical address. It checks that KVM is correctly faulting these non-classical addresses, ensuring the accuracy and stability of the KVM subsystem. The second patch includes a comprehensive PEBS test that checks all possible combinations of PEBS-related bits in MSR_IA32_PERF_CAPABILITIES. This helps to ensure the accuracy of PEBS functionality. Feedback and suggestions are welcomed and appreciated. Sincerely, Jinrong Liang Jinrong Liang (2): KVM: selftests: Test consistency of setting MSR_IA32_DS_AREA KVM: selftests: Add PEBS test for MSR_IA32_PERF_CAPABILITIES .../selftests/kvm/x86_64/vmx_pmu_caps_test.c | 171 ++++++++++++++++++ 1 file changed, 171 insertions(+) base-commit: 31b4fc3bc64aadd660c5bfa5178c86a7ba61e0f7 -- 2.31.1
