It has been updated for Intel’s v17 of the TDX host patches which was proposed here: https://lore.kernel.org/all/cover.1699368322.git.isaku.yamahata@intel.com/ The tree can be found at: https://github.com/googleprodkernel/linux-cc/tree/tdx-selftests-rfc-v5 Changes from RFC v4: Added patch to propagate KVM_EXIT_MEMORY_FAULT to userspace. Minor tweaks to align the tests to the new TDX 1.5 spec such as changes in the expected values in TDG.VP.INFO. In RFCv5, TDX selftest code is organized into: + headers in tools/testing/selftests/kvm/include/x86_64/tdx/ + common code in tools/testing/selftests/kvm/lib/x86_64/tdx/ + selftests in tools/testing/selftests/kvm/x86_64/tdx_* Dependencies + Peter’s patches, which provide functions for the host to allocate and track protected memory in the guest. https://lore.kernel.org/all/20230110175057.715453-1-pgonda@google.com/ Further work for this patch series/TODOs + Sean’s comments for the non-confidential UPM selftests patch series at https://lore.kernel.org/lkml/Y8dC8WDwEmYixJqt@google.com/T/#u apply here as well + Add ucall support for TDX selftests I would also like to acknowledge the following people, who helped review or test patches in previous versions: + Sean Christopherson + Zhenzhong Duan + Peter Gonda + Andrew Jones + Maxim Levitsky + Xiaoyao Li + David Matlack + Marc Orr + Isaku Yamahata + Maciej S.
