Browse Source 
The DXE functions are local to the DXE driver.

/**
Interface structure for the Watchdog Architectural Protocol.
@par Protocol Description:
This protocol provides a service to set the amount of time to wait
before firing the watchdog timer, and it also provides a service to
register a handler that is invoked when the watchdog timer fires.
@par When the watchdog timer fires, control will be passed to a handler
if one has been registered. If no handler has been registered,
or the registered handler returns, then the system will be
reset by calling the Runtime Service ResetSystem().
@param RegisterHandler
Registers a handler that will be called each time the
watchdogtimer interrupt fires. TimerPeriod defines the minimum
time between timer interrupts, so TimerPeriod will also
be the minimum time between calls to the registered
handler.
NOTE: If the watchdog resets the system in hardware, then
this function will not have any chance of executing.
@param SetTimerPeriod
Sets the period of the timer interrupt in 100 nS units.
This function is optional, and may return EFI_UNSUPPORTED.
If this function is supported, then the timer period will
be rounded up to the nearest supported timer period.
@param GetTimerPeriod
Retrieves the period of the timer interrupt in 100 nS units.
