[RFC PATCH 0/7] target/i386: SEV: Add support for enabling VMSA SEV features

Posted by Naveen N Rao (AMD) 2 weeks, 3 days ago

This series adds support for enabling VMSA SEV features for SEV-ES and 
SEV-SNP guests. Since that is already supported for IGVM files, some of 
that code is moved to generic path and reused.

Debug-swap is already supported in KVM today, while patches for enabling 
Secure TSC and Secure AVIC have been posted.
