Subject: [PATCH v4 03/18] KVM: x86: Add a VM type define for TDX
Date: Thu, 18 Jul 2024 14:12:15 -0700 [thread overview]
Message-ID: <20240718211230.1492011-4-rick.p.edgecombe@intel.com> (raw)
In-Reply-To: <20240718211230.1492011-1-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.
