[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.

[PATCH v3 00/75] x86: SEV-ES Guest Support
Hi,
here is the next version of changes to enable Linux to run as an SEV-ES
guest. The code was rebased to v5.7-rc3 and got a fair number of changes
since the last version.
What is SEV-ES
==============
SEV-ES is an acronym for 'Secure Encrypted Virtualization - Encrypted
State' and means a hardware feature of AMD processors which hides the
register state of VCPUs to the hypervisor by
