[RFC PATCH 00/62] Linux as SEV-ES Guest Support
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.
