*EFI_EVENT
The event is a timer event and may be passed to SetTimer().
Note that timers only function during boot services time.
The event is allocated from runtime memory. If an event is to be
signaled after the call to ExitBootServices(), the event's data
structure and notification function need to be allocated from runtime
memory. For more information, see
SetVirtualAddressMap()
The event's
NotifyContext
address. See the discussion of EVT_RUNTIME.
The event's
NotifyFunction
event is being waited on via
CheckEvent().
The event's
NotifyFunction
event is signaled via SignalEvent().
This event is to be notified by the system when
ExitBootServices()
with any other EVT bit type. The notification function for this
event is not allowed to use the Memory Allocation Services, or call
any functions that use the Memory Allocation Services, because
these services modify the current memory map.
