Subject: [PATCH v4 00/28] TDX KVM selftests
Hello,
This is v4 of the patch series for TDX selftests.
It has been updated for Intel’s v14 of the TDX host patches which was
proposed here:
https://lore.kernel.org/lkml/cover.1685333727.git.isaku.yamahata@intel.com/
The tree can be found at:
https://github.com/googleprodkernel/linux-cc/tree/tdx-selftests-rfc-v4
Changes from RFC v3:
In v14, TDX can only run with UPM enabled so the necessary changes were
made to handle that.
td_vcpu_run() was added to handle TdVmCalls that are now handled in
userspace.
The comments under the patch "KVM: selftests: Require GCC to realign
stacks on function entry" were addressed with the following patch:
https://lore.kernel.org/lkml/Y%2FfHLdvKHlK6D%2F1v@google.com/T/
And other minor tweaks were made to integrate the selftest
infrastructure onto v14.
In RFCv4, 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/lkml/20221018205845.770121-1-pgonda@google.com/T/
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 RFCv1, RFCv2, and RFCv3:
