From 3da85e633e2589a312fb3646660ef68e6a0bf18b Mon Sep 17 00:00:00 2001 From: klu2 Date: Fri, 25 Apr 2008 09:30:24 +0000 Subject: [PATCH] 1, Use PrintLib in Duet loader 2, Fix missing compress image in final disk image. I think the raw disk image had better be organized as our FD image format. I will discuss this after enabling DUET for R9. 3, Add more debug output in loader. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@5128 6f19259b-4bc3-4df7-8a09-765794883524 --- DuetPkg/BootSector/Makefile | 2 +- DuetPkg/DuetPkg.dsc | 1 + DuetPkg/EfiLdr/EfiLdr.h | 23 +- DuetPkg/EfiLdr/EfiLdr.inf | 1 + DuetPkg/EfiLdr/EfiLoader.c | 89 ++-- DuetPkg/EfiLdr/PeLoader.c | 32 +- DuetPkg/EfiLdr/TianoDecompress.c | 720 +++++++++++++++++++------------ DuetPkg/EfiLdr/TianoDecompress.h | 236 +++------- DuetPkg/PostBuild.bat | 2 +- 9 files changed, 582 insertions(+), 524 deletions(-) diff --git a/DuetPkg/BootSector/Makefile b/DuetPkg/BootSector/Makefile index cfb2a5faf5..e88743d1cf 100644 --- a/DuetPkg/BootSector/Makefile +++ b/DuetPkg/BootSector/Makefile @@ -126,7 +126,7 @@ $(BUILD_DIR)\FV\DxeIpl.z:$(BUILD_DIR)\IA32\DxeIpl.efi $(BASETOOLS_DIR)\TianoCompress -e -o $(BUILD_DIR)\FV\DxeIpl.z $(BUILD_DIR)\IA32\DxeIpl.efi $(BUILD_DIR)\FV\Efildr32:$(BUILD_DIR)\IA32\EfiLoader.efi $(BUILD_DIR)\FV\DxeIpl.z $(BUILD_DIR)\FV\DUETEFIMAINFV.z - $(BASETOOLS_DIR)\EfiLdrImage.exe -o $(BUILD_DIR)\FV\Efildr32 $(BUILD_DIR)\IA32\EfiLoader.efi $(BUILD_DIR)\FV\DxeIpl.z $(BUILD_DIR)\FV\DUETEFIMAINFV.z + $(BASETOOLS_DIR)\EfiLdrImage.exe -o $(BUILD_DIR)\FV\Efildr32 $(BUILD_DIR)\IA32\EfiLoader.efi $(BUILD_DIR)\FV\DxeIpl.z $(BUILD_DIR)\FV\DxeMain.z $(BUILD_DIR)\FV\DUETEFIMAINFV.z $(BUILD_DIR)\FV\Efildr:$(OUTPUT_DIR)\Start.com $(OUTPUT_DIR)\Efi32.com2 $(BUILD_DIR)\FV\Efildr32 copy /b $(OUTPUT_DIR)\Start.com+$(OUTPUT_DIR)\Efi32.com2+$(BUILD_DIR)\FV\Efildr32 $(BUILD_DIR)\FV\Efildr diff --git a/DuetPkg/DuetPkg.dsc b/DuetPkg/DuetPkg.dsc index e1ee50a1f7..8154f1cd9b 100644 --- a/DuetPkg/DuetPkg.dsc +++ b/DuetPkg/DuetPkg.dsc @@ -47,6 +47,7 @@ CacheMaintenanceLib|MdePkg/Library/BaseCacheMaintenanceLib/BaseCacheMaintenanceLib.inf PeCoffLib|MdePkg/Library/BasePeCoffLib/BasePeCoffLib.inf OemHookStatusCodeLib|IntelFrameworkModulePkg/Library/OemHookStatusCodeLibNull/OemHookStatusCodeLibNull.inf + PrintLib|MdePkg/Library/BasePrintLib/BasePrintLib.inf [LibraryClasses.common.DXE_DRIVER] MemoryAllocationLib|MdePkg/Library/DxeMemoryAllocationLib/DxeMemoryAllocationLib.inf diff --git a/DuetPkg/EfiLdr/EfiLdr.h b/DuetPkg/EfiLdr/EfiLdr.h index b1d0e1c272..1417b761c6 100644 --- a/DuetPkg/EfiLdr/EfiLdr.h +++ b/DuetPkg/EfiLdr/EfiLdr.h @@ -30,6 +30,7 @@ Revision History: #include #include #include +#include #define INT15_E820_AddressRangeMemory 1 #define INT15_E820_AddressRangeReserved 2 @@ -80,28 +81,6 @@ typedef struct { BIOS_MEMORY_MAP_ENTRY MemoryMapEntry[1]; } BIOS_MEMORY_MAP; -EFI_STATUS -EFIAPI -UefiDecompressGetInfo ( - IN EFI_TIANO_DECOMPRESS_PROTOCOL *This, - IN VOID *Source, - IN UINT32 SrcSize, - OUT UINT32 *DstSize, - OUT UINT32 *ScratchSize - ); - -EFI_STATUS -EFIAPI -TianoDecompress ( - IN EFI_TIANO_DECOMPRESS_PROTOCOL *This, - IN VOID *Source, - IN UINT32 SrcSize, - IN OUT VOID *Destination, - IN UINT32 DstSize, - IN OUT VOID *Scratch, - IN UINT32 ScratchSize - ); - EFILDR_LOADED_IMAGE DxeCoreImage; EFILDR_LOADED_IMAGE DxeIplImage; diff --git a/DuetPkg/EfiLdr/EfiLdr.inf b/DuetPkg/EfiLdr/EfiLdr.inf index 4d980bca72..5e9b676ed9 100644 --- a/DuetPkg/EfiLdr/EfiLdr.inf +++ b/DuetPkg/EfiLdr/EfiLdr.inf @@ -37,6 +37,7 @@ BaseLib BaseMemoryLib UefiApplicationEntryPoint + PrintLib [Sources.common] Debug.h diff --git a/DuetPkg/EfiLdr/EfiLoader.c b/DuetPkg/EfiLdr/EfiLoader.c index 382b7802a1..c8c749ba4d 100644 --- a/DuetPkg/EfiLdr/EfiLoader.c +++ b/DuetPkg/EfiLdr/EfiLoader.c @@ -22,6 +22,18 @@ Revision History: #include "Support.h" #include "Debug.h" #include "PeLoader.h" +#include "TianoDecompress.h" + +STATIC +VOID +SystemHang( + VOID + ) +{ + CHAR8 PrintBuffer[256]; + AsciiSPrint (PrintBuffer, 256, "## FATEL ERROR ##: Fail to load DUET images!
