Subject: Re: [RFC PATCH 0/5] Extend SEV-SNP SVSM support with a kvm_vcpu per VMPL

I couldn't attend KVM forum, but I understand based on feedback at a
session there, Paolo took the lead to provide an architecture document
for this feature, is that correct?  Just asking because I haven't
noticed anything about this on the list.
