SmiHandlerProfileRegisterHandler()

EFI_STATUS EFIAPI SmiHandlerProfileRegisterHandler	(	IN EFI_GUID *	HandlerGuid,
		IN EFI_SMM_HANDLER_ENTRY_POINT2	Handler,
		IN PHYSICAL_ADDRESS	CallerAddress,
		IN VOID *Context	OPTIONAL,
		IN UINTN ContextSize	OPTIONAL
	)

This function is called by SmmChildDispatcher module to report a new SMI handler is registered, to SmmCore.

Parameters

HandlerGuid	The GUID to identify the type of the handler. For the SmmChildDispatch protocol, the HandlerGuid must be the GUID of SmmChildDispatch protocol.
Handler	The SMI handler.
CallerAddress	The address of the module who registers the SMI handler.
Context	The context of the SMI handler. For the SmmChildDispatch protocol, the Context must match the one defined for SmmChildDispatch protocol.
ContextSize	The size of the context in bytes. For the SmmChildDispatch protocol, the Context must match the one defined for SmmChildDispatch protocol.

Return values

EFI_SUCCESS	The information is recorded.
EFI_UNSUPPORTED	The feature is unsupported.
EFI_OUT_OF_RESOURCES	There is no enough resource to record the information.

SmiHandlerProfileUnregisterHandler()

EFI_STATUS EFIAPI SmiHandlerProfileUnregisterHandler	(	IN EFI_GUID *	HandlerGuid,
		IN EFI_SMM_HANDLER_ENTRY_POINT2	Handler,
		IN VOID *Context	OPTIONAL,
		IN UINTN ContextSize	OPTIONAL
	)

This function is called by SmmChildDispatcher module to report an existing SMI handler is unregistered, to SmmCore.

Parameters

HandlerGuid	The GUID to identify the type of the handler. For the SmmChildDispatch protocol, the HandlerGuid must be the GUID of SmmChildDispatch protocol.
Handler	The SMI handler.
Context	The context of the SMI handler. If it is NOT NULL, it will be used to check what is registered.
ContextSize	The size of the context in bytes. If Context is NOT NULL, it will be used to check what is registered.
