Abstract:

NT Emulation Timer Architectural Protocol Driver as defined in DXE CIS
|

|

This Timer module uses an NT Thread to simulate the timer-tick driven
|
||||
timer service. In the future, the Thread creation should possibly be
|
||||
abstracted by the CPU architectural protocol

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.

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.
