PiMmCpuTpFwRootMmiHandler()

EFI_STATUS EFIAPI PiMmCpuTpFwRootMmiHandler	(	IN EFI_HANDLE	DispatchHandle,
		IN CONST VOID *Context	OPTIONAL,
		IN OUT VOID *CommBuffer	OPTIONAL,
		IN OUT UINTN *CommBufferSize	OPTIONAL
	)

This function is the main entry point for an MM handler dispatch or communicate-based callback.

Parameters

DispatchHandle	The unique handle assigned to this handler by MmiHandlerRegister().
Context	Points to an optional handler context which was specified when the handler was registered.
CommBuffer	A pointer to a collection of data in memory that will be conveyed from a non-MM environment into an MM environment.
CommBufferSize	The size of the CommBuffer.
