From: Joerg Roedel <jroedel@xxxxxxx> Hi, here is a small set of patches which I took from the pending SEV-SNP patch-sets to enable basic support for GHCB protocol version 2. When SEV-SNP is not supported, only two new MSR protocol VMGEXIT calls need to be supported: - MSR-based AP-reset-hold - MSR-based HV-feature-request These calls are implemented by here and then the protocol is lifted to version 2. This is submitted separately because the MSR-based AP-reset-hold call is required to support kexec/kdump in SEV-ES guests. Regards, Joerg Changes v1->v2: - Rebased to v5.14-rc2 - Addressed Sean's review comments from the SNP patch-set.
