Module produces EDK gEfiPrintProtocolGuid for backward compatibility support.
|
|
|
|
EDK II retires old EDK Print Protocol and this module produces
|
|
gEfiPrintProtocolGuid based on PrintLib:
|
|
1) If it links against BasePrintLib in MdePkg, it produces gEfiPrintProtocolGuid
|
|
without any prerequisites.
|
|
2) If it links against DxePrintLibPrint2Protocol in MdeModulePkg, it produces
|
|
gEfiPrintProtocolGuid on top of gEfiPrint2ProtocolGuid.
