Hello Ard,

what is your idea how the EFI_RT_PROPERTIES_TABLE shall be exposed to
the efi_test driver?

Will the EFI runtime wrapper simply return EFI_UNSUPPORTED if the
function is not marked as supported in the table? Or will the
configuration table itself be make available?

Best regards

Heinrich
