From 2ad4dad029f3931e952ca6c766cab815aa930a17 Mon Sep 17 00:00:00 2001 From: lgao4 Date: Fri, 12 Oct 2007 08:13:33 +0000 Subject: [PATCH] 1. Update internal EfiPrint protocol to contain all print interfaces provided by PrintLib class of MdePkg. 2. Update SetupBrowserDxe driver to produce new EfiPrint protocol. 3. Update EdkDxePrintLib instance to implement all interfaces defined in PrintLib class based on new EfiPrint protocol. 4. Update Nt32Pkg platform.dsc to use EdkDxePrintLib instance for UEFI_APPLICATION modules. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4109 6f19259b-4bc3-4df7-8a09-765794883524 --- .../Universal/SetupBrowserDxe/Setup.c | 10 +- MdeModulePkg/Include/Protocol/Print.h | 57 +- .../Library/EdkDxePrintLib/PrintLib.c | 543 +++++++++++++++--- MdeModulePkg/MdeModulePkg.dec | 2 +- MdePkg/Library/UefiLib/UefiLibPrint.c | 2 +- Nt32Pkg/Nt32Pkg.dsc | 1 + 6 files changed, 534 insertions(+), 81 deletions(-) diff --git a/IntelFrameworkModulePkg/Universal/SetupBrowserDxe/Setup.c b/IntelFrameworkModulePkg/Universal/SetupBrowserDxe/Setup.c index e2f4634cf1..8000b4ce7d 100644 --- a/IntelFrameworkModulePkg/Universal/SetupBrowserDxe/Setup.c +++ b/IntelFrameworkModulePkg/Universal/SetupBrowserDxe/Setup.c @@ -2203,7 +2203,15 @@ Returns: } EFI_HANDLE PrintHandle = NULL; -EFI_PRINT_PROTOCOL mPrintProtocol = { UnicodeVSPrint }; +EFI_PRINT_PROTOCOL mPrintProtocol = +{ + UnicodeVSPrint, + UnicodeVSPrintAsciiFormat, + UnicodeValueToString, + AsciiVSPrint, + AsciiVSPrintUnicodeFormat, + AsciiValueToString +}; STATIC EFI_STATUS diff --git a/MdeModulePkg/Include/Protocol/Print.h b/MdeModulePkg/Include/Protocol/Print.h index c381295f31..b640cb0b2f 100644 --- a/MdeModulePkg/Include/Protocol/Print.h +++ b/MdeModulePkg/Include/Protocol/Print.h @@ -23,7 +23,7 @@ Abstract: #define __PPRINT_H__ #define EFI_PRINT_PROTOCOL_GUID \ - { 0xdf2d868e, 0x32fc, 0x4cf0, {0x8e, 0x6b, 0xff, 0xd9, 0x5d, 0x13, 0x43, 0xd0 } } + { 0x5bcc3dbc, 0x8c57, 0x450a, { 0xbb, 0xc, 0xa1, 0xc0, 0xbd, 0xde, 0x48, 0xc } } // // Forward reference for pure ANSI compatability @@ -33,18 +33,67 @@ typedef struct _EFI_PRINT_PROTOCOL EFI_PRINT_PROTOCOL; typedef UINTN -(EFIAPI *EFI_VSPRINT) ( +(EFIAPI *UNI_VSPRINT) ( OUT CHAR16 *StartOfBuffer, IN UINTN BufferSize, IN CONST CHAR16 *FormatString, IN VA_LIST Marker ); +typedef +UINTN +(EFIAPI *UNI_VSPRINT_ASCII) ( + OUT CHAR16 *StartOfBuffer, + IN UINTN BufferSize, + IN CONST CHAR8 *FormatString, + IN VA_LIST Marker + ); + +typedef +UINTN +(EFIAPI *VALUE_TO_UNISTRING) ( + IN OUT CHAR16 *Buffer, + IN UINTN Flags, + IN INT64 Value, + IN UINTN Width + ); + +typedef +UINTN +(EFIAPI *ASCII_VSPRINT) ( + OUT CHAR8 *StartOfBuffer, + IN UINTN BufferSize, + IN CONST CHAR8 *FormatString, + IN VA_LIST Marker + ); + +typedef +UINTN +(EFIAPI *ASCII_VSPRINT_UNI) ( + OUT CHAR8 *StartOfBuffer, + IN UINTN BufferSize, + IN CONST CHAR16 *FormatString, + IN VA_LIST Marker + ); + +typedef +UINTN +(EFIAPI *VALUE_TO_ASCIISTRING) ( + IN OUT CHAR8 *Buffer, + IN UINTN Flags, + IN INT64 Value, + IN UINTN Width + ); + struct _EFI_PRINT_PROTOCOL { - EFI_VSPRINT VSPrint; + UNI_VSPRINT VSPrint; + UNI_VSPRINT_ASCII UniVSPrintAscii; + VALUE_TO_UNISTRING UniValueToString; + ASCII_VSPRINT AsciiVSPrint; + ASCII_VSPRINT_UNI AsciiVSPrintUni; + VALUE_TO_ASCIISTRING AsciiValueToString; }; - extern EFI_GUID gEfiPrintProtocolGuid; #endif diff --git a/MdeModulePkg/Library/EdkDxePrintLib/PrintLib.c b/MdeModulePkg/Library/EdkDxePrintLib/PrintLib.c index 5d781ebdda..2194015b8d 100644 --- a/MdeModulePkg/Library/EdkDxePrintLib/PrintLib.c +++ b/MdeModulePkg/Library/EdkDxePrintLib/PrintLib.c @@ -19,9 +19,6 @@ Abstract: --*/ - - - #include #include @@ -31,39 +28,12 @@ Abstract: static EFI_PRINT_PROTOCOL *gPrintProtocol = NULL; -UINTN -UnicodeVSPrint ( - OUT CHAR16 *StartOfBuffer, - IN UINTN BufferSize, - IN const CHAR16 *FormatString, - IN VA_LIST Marker +EFI_STATUS +EFIAPI +InternalLocatePrintProtocol ( ) -/*++ - -Routine Description: - - VSPrint function to process format and place the results in Buffer.
