46   This function registers the handler NotifyFunction so it is called every time
48   handler call to the NotifyFunction.  If NotifyFunction is NULL, then the
49   handler is unregistered.  If the handler is registered, then EFI_SUCCESS is
50   returned.  If the CPU does not support registering a timer interrupt handler,
51   then EFI_UNSUPPORTED is returned.  If an attempt is made to register a handler
52   when a handler is already registered, then EFI_ALREADY_STARTED is returned.
53   If an attempt is made to unregister a handler when a handler is not registered,
61                            register a handler for the timer interrupt, so it can know
63                            signal timer based events. NULL will unregister the handler.
65   @retval EFI_SUCCESS           The timer handler was registered.
67   @retval EFI_ALREADY_STARTED   NotifyFunction is not NULL, and a handler is already
69   @retval EFI_INVALID_PARAMETER NotifyFunction is NULL, and a handler was not
71   @retval EFI_DEVICE_ERROR      The timer handler could not be registered.
138   If a handler has been registered through the EFI_TIMER_ARCH_PROTOCOL.RegisterHandler()
140   enabled when this service is called, then the registered handler will be invoked. The
141   registered handler should not be able to distinguish a hardware-generated timer
158 /// interrupt, and to register a handler that is called each time the timer
160 /// periodic timer interrupt.  When a timer interrupt occurs, the handler is
