Out of curiosity, is there any public branch you can share (assuming
that the KVM side prototype of SME support is under development) or are
there already some patches on the list that I hadn't noticed? Having
asked that, I'm pretty happy to be Cc-ed on that once it gets ready so
that I can start testing things on the emulator (or on real HW, if
possible) and participate in the review.

Thanks,
Zenghui
