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.
