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 ARM-based specific relocation fixup and is a no-op on other instruction sets.

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 ARM-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.

ThumbMovtImmediatePatch()

VOID ThumbMovtImmediatePatch	(	IN OUT UINT16 *	Instruction,
		IN UINT16	Address
	)

Update an ARM MOVT or MOVW immediate instruction immediate data.

Parameters

Instruction	Pointer to ARM MOVT or MOVW immediate instruction
Address	New addres to patch into the instruction

Definition at line 52 of file PeCoffLoaderEx.c.

ThumbMovwMovtImmediateAddress()

UINT32 ThumbMovwMovtImmediateAddress

(

IN UINT16 *

Instructions

)

Pass in a pointer to an ARM MOVW/MOVT instruciton pair and return the immediate data encoded in the two` instruction.

Parameters

Instructions

Pointer to ARM MOVW/MOVT insturction pair

Returns

Immediate address encoded in the instructions

Definition at line 83 of file PeCoffLoaderEx.c.

ThumbMovwMovtImmediatePatch()

VOID ThumbMovwMovtImmediatePatch	(	IN OUT UINT16 *	Instructions,
		IN UINT32	Address
	)

Update an ARM MOVW/MOVT immediate instruction instruction pair.

Parameters

Instructions	Pointer to ARM MOVW/MOVT instruction pair
Address	New addres to patch into the instructions
