I do many runs of QEMU/sbsa-ref with logging= and all those ANSI colour codes only make problems.


These are the supported consoles [1]

EFI_GUID  *mTerminalType[] =3D {
 = ; &gEfiPcAnsiGuid,
  &gEfiVT100Guid,
 = ; &gEfiVT100PlusGuid,
  &gEfiVTUTF8Guid,
&= nbsp; &gEfiTtyTermGuid,
  &gEdkiiLinuxTermGuid,
  &gEdkiiXtermR6Guid,
  &gEdkiiVT400Guid,=
  &gEdkiiSCOTermGuid
};

<= div>CHAR16  *mSerialConsoleNames[] =3D {
  L"PC-ANSI Se= rial Console",
  L"VT-100 Serial Console",
  = L"VT-100+ Serial Console",
  L"VT-UTF8 Serial Console",
  L"Tty Terminal Serial Console",
  L"Linux Termi= nal Serial Console",
  L"Xterm R6 Serial Console",
  L"VT-400 Serial Console",
  L"SCO Terminal Serial Co= nsole"
};

I think the OVMF default= is coming from here [2]
VENDOR_DEVICE_PATH    gTermina= lTypeDeviceNode    =3D gVtUtf8Terminal;

= If you look up gVtUtf8Terminal you see [3]
#define gVtUtf8Te= rminal \
  { \
    { \
  =     MESSAGING_DEVICE_PATH, \
      MSG_V= ENDOR_DP, \
      { \
    &nbs= p;   (UINT8) (sizeof (VENDOR_DEVICE_PATH)), \
    =     (UINT8) ((sizeof (VENDOR_DEVICE_PATH)) >> 8) \
      } \
    }, \
  &n= bsp; DEVICE_PATH_MESSAGING_VT_UTF8 \
  }

Thus we get to the TL;DR part=E2=80=A6 The console NVRAM variables th= at point to the UART has a MESSAGING_DEVICE_PATH MSG_VENDOR_DP node af= ter the UART definition that has a UUID (EFI_GUID) that defines the type of= terminal emulation to use. 

The definition o= f the ConIn and ConOut variables is here [4]


Thanks,
