Subject: [PATCH v18 020/121] x86/virt/tdx: Get system-wide info about TDX module on initialization
Date: Mon, 22 Jan 2024 15:52:56 -0800 [thread overview]
Message-ID: <d82142369de93661bdb57b8819a409694cede56e.1705965634.git.isaku.yamahata@intel.com> (raw)
In-Reply-To: <cover.1705965634.git.isaku.yamahata@intel.com>
From: Isaku Yamahata <isaku.yamahata@intel.com>
TDX KVM needs system-wide information about the TDX module, store it in
struct tdx_info.
TODO: Once TDX host patch series introduces a framework to read TDX meta
data, convert the code to it.
