Function Documentation

PeCoffLoaderImageFormatSupported()

BOOLEAN PeCoffLoaderImageFormatSupported

(

IN UINT16

Machine

)

Returns TRUE if the machine type of PE/COFF image is supported. Supported does not mean the image can be executed it means the PE/COFF loader supports loading and relocating of the image type. It's up to the caller to support the entry point.

Parameters

Machine

Machine type from the PE Header.

Returns

TRUE if this PE/COFF loader can load the image

PeCoffLoaderRelocateImageEx()

RETURN_STATUS PeCoffLoaderRelocateImageEx	(	IN UINT16 *	Reloc,
		IN OUT CHAR8 *	Fixup,
		IN OUT CHAR8 **	FixupData,
		IN UINT64	Adjust
	)

Performs an RISC-V specific relocation fixup and is a no-op on other instruction sets. RISC-V splits 32-bit fixup into 20bit and 12-bit with two relocation types. We have to know the lower 12-bit fixup first then we can deal carry over on high 20-bit fixup. So we log the high 20-bit in FixupData.

Parameters

Reloc	The pointer to the relocation record.
Fixup	The pointer to the address to fix up.
FixupData	The pointer to a buffer to log the fixups.
Adjust	The offset to adjust the fixup.

Returns

Status code.

PeHotRelocateImageEx()

RETURN_STATUS PeHotRelocateImageEx	(	IN UINT16 *	Reloc,
		IN OUT CHAR8 *	Fixup,
		IN OUT CHAR8 **	FixupData,
		IN UINT64	Adjust
	)

Performs an Itanium-based specific re-relocation fixup and is a no-op on other instruction sets. This is used to re-relocated the image into the EFI virtual space for runtime calls.

Parameters

Reloc	The pointer to the relocation record.
Fixup	The pointer to the address to fix up.
FixupData	The pointer to a buffer to log the fixups.
Adjust	The offset to adjust the fixup.

Returns

Status code.
