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

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
|

signal timer based events. NULL will unregister the handler.

Returns:

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:
|

|

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.

|

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.

/*++
|

|

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.

This function generates a soft timer interrupt. If the platform does not support soft

|

If a handler has been registered through the EFI_TIMER_ARCH_PROTOCOL.RegisterHandler()

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
