I've prepared this series as an extension to the RFC patch series:
'SEV-SNP support for running an SVSM' posted by Tom Lendacky [1].
This extends the support for transitioning a vCPU between VM
Privilege Levels (VMPLs) by storing the vCPU state for each VMPL in
its own `struct kvm_vcpu`. This additionally allows for separate
APICs for each 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?
Yep.
Just asking because I haven't noticed anything about this on the list.
Heh, there's quite a queue of blocked readers (and writers!) at this point ;-)
Well, at least one person had a writer's block instead.
I had it almost ready but then noticed a few hiccups in the design we
came up with, and have been seating on it for a while. I'm sending it
now, finishing the commit messages.
