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

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.
