/*++
Routine Description:
This function registers the handler NotifyFunction so it is called every time
the timer interrupt fires. It also passes the amount of time since the last
handler call to the NotifyFunction. If NotifyFunction is NULL, then the
handler is unregistered. If the handler is registered, then EFI_SUCCESS is
returned. If the CPU does not support registering a timer interrupt handler,
then EFI_UNSUPPORTED is returned. If an attempt is made to register a handler
when a handler is already registered, then EFI_ALREADY_STARTED is returned.
If an attempt is made to unregister a handler when a handler is not registered,
then EFI_INVALID_PARAMETER is returned. If an error occurs attempting to
register the NotifyFunction with the timer interrupt, then EFI_DEVICE_ERROR
is returned.
Arguments:
This - The EFI_TIMER_ARCH_PROTOCOL instance.
NotifyFunction - The function to call when a timer interrupt fires. This
function executes at TPL_HIGH_LEVEL. The DXE Core will
register a handler for the timer interrupt, so it can know
how much time has passed. This information is used to
signal timer based events. NULL will unregister the handler.
Returns:
EFI_SUCCESS - The timer handler was registered.
EFI_UNSUPPORTED - The platform does not support timer interrupts.
EFI_ALREADY_STARTED - NotifyFunction is not NULL, and a handler is already
registered.
EFI_INVALID_PARAMETER - NotifyFunction is NULL, and a handler was not
previously registered.
EFI_DEVICE_ERROR - The timer handler could not be registered.

WinNtTimerDriverSetTimerPeriod (

/*++
Routine Description:
This function adjusts the period of timer interrupts to the value specified
by TimerPeriod. If the timer period is updated, then the selected timer
period is stored in EFI_TIMER.TimerPeriod, and EFI_SUCCESS is returned. If
the timer hardware is not programmable, then EFI_UNSUPPORTED is returned.
If an error occurs while attempting to update the timer period, then the
timer hardware will be put back in its state prior to this call, and
EFI_DEVICE_ERROR is returned. If TimerPeriod is 0, then the timer interrupt
is disabled. This is not the same as disabling the CPU's interrupts.
Instead, it must either turn off the timer hardware, or it must adjust the
interrupt controller so that a CPU interrupt is not generated when the timer
interrupt fires.
Arguments:
This - The EFI_TIMER_ARCH_PROTOCOL instance.
TimerPeriod - The rate to program the timer interrupt in 100 nS units. If
the timer hardware is not programmable, then EFI_UNSUPPORTED is
returned. If the timer is programmable, then the timer period
will be rounded up to the nearest timer period that is supported
by the timer hardware. If TimerPeriod is set to 0, then the
timer interrupts will be disabled.
Returns:
EFI_SUCCESS - The timer period was changed.
EFI_UNSUPPORTED - The platform cannot change the period of the timer interrupt.
EFI_DEVICE_ERROR - The timer period could not be changed due to a device error.

service, then a soft timer interrupt will be generated. If the timer interrupt is
enabled when this service is called, then the registered handler will be invoked. The
registered handler should not be able to distinguish a hardware-generated timer
interrupt from a software-generated timer interrupt.
