Hi, here is the first public post of the patch-set to enable Linux to run under SEV-ES enabled hypervisors. The code is mostly feature-complete, but there are still a couple of bugs to fix. Nevertheless, given the size of the patch-set, I think it is about time to ask for initial feedback of the changes that come with it. To better understand the code here is a quick explanation of SEV-ES first.
