I appreciate your patience. But as a cursory look, I'm happy that you've written the hardware-side code for this. That's a great starting point. The plumbing is not so nice, though. This needs to be integrated more closely with random.c itself, similar to how vmgenid works. When I'm back in a few weeks, I'll see if I can either write a description of what I have in mind, or simply integrate the useful hardware work here into an expanded patch series. [Please don't merge anything for now.] Jason
