We have some selftests that are built on the basic TDX selftests. One just
hammers the MMU stuff with a bunch of zaps and also weird stuff from the guest.
It was eventually too much work to try to keep the internal enhancements rebased
nicely so we actually just run an old branch's TDX selftests against newer
kernels. So the branch is a bit of a pile, and not really suitable for sharing.
We plan to clean it and upstream it when the path clears. So it would really
help to get those basic ones upstream. We remain happy to help, so please let us
know.
