+ can use the CheckEvent() or WaitForEvent()\r
+ services to check the state of event. Type\r

+ Specification.\r
+ @param[in] TimeoutInMicrosecsond Indicates the time limit in microseconds for\r
+ this AP to finish this Procedure, either for\r
+ blocking or non-blocking mode. Zero means\r
+ infinity. If the timeout expires before\r
+ this AP returns from Procedure, then Procedure\r
+ on the AP is terminated. The\r
+ AP is available for next function assigned\r
+ by MpInitLibStartupAllAPs() or\r
+ MpInitLibStartupThisAP().\r
+ If the timeout expires in blocking mode,\r
+ BSP returns EFI_TIMEOUT. If the timeout\r
+ expires in non-blocking mode, WaitEvent\r
+ is signaled with SignalEvent().\r
