Subject: [PATCH v6 03/18] KVM: x86: Add a VM type define for TDX
Date: Sun, 22 Dec 2024 14:34:30 -0500 [thread overview]
Message-ID: <20241222193445.349800-4-pbonzini@redhat.com> (raw)
In-Reply-To: <20241222193445.349800-1-pbonzini@redhat.com>
From: Rick Edgecombe <rick.p.edgecombe@intel.com>
Add a VM type define for TDX.
Future changes will need to lay the ground work for TDX support by
making some behavior conditional on the VM being a TDX guest.
