    Subject[PATCH v7 005/102] x86/virt/vmx/tdx: export platform_tdx_enabled()
    Date
    From: Isaku Yamahata <isaku.yamahata@intel.com>

    TDX KVM uses platform_tdx_enabled() via vmx_hardware_setup() to check if the
    platform supports TDX, concretely CPU SEAM mode, irrespective of TDX module
    is loaded or initialized.
