Subject: [PATCH v2 19/20] KVM: TDX: Make TDX VM type supported
Date: Thu, 27 Feb 2025 09:20:20 +0800 [thread overview]
Message-ID: <20250227012021.1778144-20-binbin.wu@linux.intel.com> (raw)
In-Reply-To: <20250227012021.1778144-1-binbin.wu@linux.intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
Now all the necessary code for TDX is in place, it's ready to run TDX
guest. Advertise the VM type of KVM_X86_TDX_VM so that the user space
VMM like QEMU can start to use it.
