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
