Ard, Just a few comments: * Please pre-initialize global mEfiAtRuntime = FALSE; * The UNI file in the patch is identical to BaseDebugLibSerialPort. Please update UNI file header and strings to describe this as the runtime version of the DebugLib as described in the .inf and .C files. * gEfiMdePkgTokenSpaceGuid.PcdDebugClearMemoryValue should be SOMETIMES_CONSUMES in the INF file.
