MemoryProfileLibRecord()

EFI_STATUS EFIAPI MemoryProfileLibRecord	(	IN PHYSICAL_ADDRESS	CallerAddress,
		IN MEMORY_PROFILE_ACTION	Action,
		IN EFI_MEMORY_TYPE	MemoryType,
		IN VOID *	Buffer,
		IN UINTN	Size,
		IN CHAR8 *ActionString	OPTIONAL
	)

Record memory profile of multilevel caller.

Parameters

[in]	CallerAddress	Address of caller.
[in]	Action	Memory profile action.
[in]	MemoryType	Memory type. EfiMaxMemoryType means the MemoryType is unknown.
[in]	Buffer	Buffer address.
[in]	Size	Buffer size.
[in]	ActionString	String for memory profile action. Only needed for user defined allocate action.

Returns

EFI_SUCCESS Memory profile is updated.

EFI_UNSUPPORTED Memory profile is unsupported, or memory profile for the image is not required, or memory profile for the memory type is not required.

EFI_ACCESS_DENIED It is during memory profile data getting.

EFI_ABORTED Memory profile recording is not enabled.

EFI_OUT_OF_RESOURCES No enough resource to update memory profile for allocate action.

EFI_NOT_FOUND No matched allocate info found for free action.
