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.

From: Joerg Roedel <jroedel at suse.de> Hi, here is a rebased version of the latest SEV-ES patches. They are now based on latest tip/master instead of upstream Linux and include the necessary changes. Changes to v4 are in particular: - Moved early IDT setup code to idt.c, because the idt_descr and the idt_table are now static - This required to make stack protector work early (or

From: Joerg Roedel <jroedel at suse.de> Hi, here is the fourth version of the SEV-ES Guest Support patches. I addressed the review comments sent to me for the previous version and rebased the code v5.8-rc5. The biggest change in this version is the IST handling code for the #VC handler. I adapted the entry code for the #VC handler to the big pile of entry code changes merged into

From: Joerg Roedel <jroedel at suse.de> Hi, here is the new version of the SEV-ES client enabling patch-set. It is based on the latest tip/master branch and contains the necessary changes. In particular those ar: - Enabling CR4.FSGSBASE early on supported processors so that early #VC exceptions on APs can be handled. - Add another patch (patch 1) to fix a KVM frame-size build

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
