2026-04-20KVM: selftests: Use u64 instead of uint64_tDavid Matlack
Use u64 instead of uint64_t to make the KVM selftests code more concise and more similar to the kernel (since selftests are primarily developed by kernel developers). This commit was generated with the following command: git ls-files tools/testing/selftests/kvm | xargs sed -i 's/uint64_t/u64/g' Then by manually adjusting whitespace to make checkpatch.pl happy. Include <linux/types.h> in include/kvm_util_types.h, iinclude/test_util.h, and include/x86/pmu.h to pick up the tools-defined u64. Arguably, all headers (especially kvm_util_types.h) should have already been including stdint.h to get uint64_t from the libc headers, but the missing dependency only rears its head once KVM uses u64 instead of uint64_t. No functional change intended.

2026-01-08KVM: selftests: Extend vmx_set_nested_state_test to cover SVMYosry Ahmed
Add test cases for the validation checks in svm_set_nested_state(), and allow the test to run with SVM as well as VMX. The SVM test also makes sure that KVM_SET_NESTED_STATE accepts GIF being set or cleared if EFER.SVME is cleared, verifying a recently fixed bug where GIF was incorrectly expected to always be set when EFER.SVME is cleared.
