From 3d7b0992fccc89cc049de91d02b4869ec81cf9fb Mon Sep 17 00:00:00 2001 From: lgao4 Date: Fri, 28 Sep 2007 08:14:30 +0000 Subject: 1. Replace PeCoffLoader library by PeCoff lib for PeiCore, DxeIpl and DxeMain. 2. Add three PeCoff library instances for NT32 PeImage load. 3. Update PeCoffGetEntryPointLib to support TeImage. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@3965 6f19259b-4bc3-4df7-8a09-765794883524 --- .../PeCoffGetEntryPoint.c | 168 ++++++++++++++++++++- 1 file changed, 160 insertions(+), 8 deletions(-) (limited to 'Nt32Pkg/Library/Nt32PeiPeCoffGetEntryPointLib') diff --git a/Nt32Pkg/Library/Nt32PeiPeCoffGetEntryPointLib/PeCoffGetEntryPoint.c b/Nt32Pkg/Library/Nt32PeiPeCoffGetEntryPointLib/PeCoffGetEntryPoint.c index 4f3c505cdd..70647426fa 100644 --- a/Nt32Pkg/Library/Nt32PeiPeCoffGetEntryPointLib/PeCoffGetEntryPoint.c +++ b/Nt32Pkg/Library/Nt32PeiPeCoffGetEntryPointLib/PeCoffGetEntryPoint.c @@ -27,6 +27,7 @@ Revision History #include #include #include +#include RETURN_STATUS @@ -63,15 +64,16 @@ Returns: UINT64 ImageSize; EFI_PHYSICAL_ADDRESS ImageEntryPoint; + ASSERT (Pe32Data != NULL); + ASSERT (EntryPoint != NULL); + Status = PeiServicesLocatePpi ( &gNtPeiLoadFilePpiGuid, 0, &PpiDescriptor, &PeiNtService ); - if (EFI_ERROR (Status)) { - return Status; - } + ASSERT_EFI_ERROR (Status); Status = PeiNtService->PeiLoadFileService ( Pe32Data, @@ -79,6 +81,10 @@ Returns: &ImageSize, &ImageEntryPoint ); + if (EFI_ERROR (Status)) { + return Status; + } + *EntryPoint = (VOID*)(UINTN)ImageEntryPoint; return Status; } @@ -90,9 +96,9 @@ Returns: level debug. - @param Image Pointer to a PE/COFF header + @param Pe32Data Pointer to a PE/COFF header - @return Machine type or zero if not a valid iamge + @return Machine type or zero if not a valid iamge **/ UINT16 @@ -104,17 +110,163 @@ PeCoffLoaderGetMachineType ( EFI_IMAGE_OPTIONAL_HEADER_PTR_UNION Hdr; EFI_IMAGE_DOS_HEADER *DosHdr; + ASSERT (Pe32Data != NULL); + DosHdr = (EFI_IMAGE_DOS_HEADER *)Pe32Data; if (DosHdr->e_magic == EFI_IMAGE_DOS_SIGNATURE) { - Hdr.Pe32 = (EFI_IMAGE_NT_HEADERS32 *)((UINTN)Pe32Data + DosHdr->e_lfanew); + // + // DOS image header is present, so read the PE header after the DOS image header. + // + Hdr.Pe32 = (EFI_IMAGE_NT_HEADERS32 *)((UINTN) Pe32Data + (UINTN) ((DosHdr->e_lfanew) & 0x0ffff)); } else { - Hdr.Pe32 = (EFI_IMAGE_NT_HEADERS32 *)((UINTN)Pe32Data); + // + // DOS image header is not present, so PE header is at the image base. + // + Hdr.Pe32 = (EFI_IMAGE_NT_HEADERS32 *)Pe32Data; } - if (Hdr.Pe32->Signature == EFI_IMAGE_NT_SIGNATURE) { + if (Hdr.Te->Signature == EFI_TE_IMAGE_HEADER_SIGNATURE) { + return Hdr.Te->Machine; + } else if (Hdr.Pe32->Signature == EFI_IMAGE_NT_SIGNATURE) { return Hdr.Pe32->FileHeader.Machine; } return 0x0000; } +/** + Returns a pointer to the PDB file name for a PE/COFF image that has been + loaded into system memory with the PE/COFF Loader Library functions. + + Returns the PDB file name for the PE/COFF image specified by Pe32Data.
