I'm setting up a CI system that the team is using to test updates to the different TDX patch series, and it currently runs the KVM Unit tests, and kvm selftests, and we'd like to be able to add these three new TDX tests to that as well. I tried to take a quick shot at rebasing it, but ran into several conflicts since kvm-coco-queue has in the meantime made changes e.g. in tools/testing/selftests/kvm/lib/x86_64/processor.c vcpu_setup(). If you can help rebase this, Rick's MMU prep series might be a good baseline to use: https://lore.kernel.org/all/20240530210714.364118-1-rick.p.edgecombe@xxxxxxxxx/ This is also available in a tree at: https://github.com/intel/tdx/tree/tdx_kvm_dev-2024-05-30 Thank you, Vishal > > 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@xxxxxxxxxx/ > > 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@xxxxxxxxxx/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 <seanjc@xxxxxxxxxx> > + Zhenzhong Duan <zhenzhong.duan@xxxxxxxxx> > + Peter Gonda <pgonda@xxxxxxxxxx> > + Andrew Jones <drjones@xxxxxxxxxx> > + Maxim Levitsky <mlevitsk@xxxxxxxxxx> > + Xiaoyao Li <xiaoyao.li@xxxxxxxxx> > + David Matlack <dmatlack@xxxxxxxxxx> > + Marc Orr <marcorr@xxxxxxxxxx> > + Isaku Yamahata <isaku.yamahata@xxxxxxxxx> > + Maciej S.
