Subject: [PATCH v3 0/2] KVM: SEV: Improve GHCB Version Handling for SEV-ES/SEV-SNP
Date: Mon, 4 Aug 2025 14:39:43 +0530 [thread overview]
Message-ID: <20250804090945.267199-1-nikunj@amd.com> (raw)
As discussed here[1]:
Refactor SEV's GHCB version handling to improve clarity and ABI stability.
* Set the default GHCB version (2) for SEV-ES guests earlier in the flow
* Remove the GHCB_VERSION_DEFAULT macro in favor of hardcoded values to
prevent potential ABI issues
* Improve comments to better explain version requirements.
* Enforce minimum GHCB version for SEV-SNP guests.
Patches are based on kvm/next
