-/**
- This service executes a caller provided function on all enabled APs. APs can
- run either simultaneously or one at a time in sequence. This service supports
- both blocking and non-blocking requests. The non-blocking requests use EFI
- events so the BSP can detect when the APs have finished. This service may only
- be called from the BSP.
-
- This function is used to dispatch all the enabled APs to the function specified
- by Procedure. If any enabled AP is busy, then EFI_NOT_READY is returned
- immediately and Procedure is not started on any AP.
-
- If SingleThread is TRUE, all the enabled APs execute the function specified by
- Procedure one by one, in ascending order of processor handle number. Otherwise,
- all the enabled APs execute the function specified by Procedure simultaneously.
-
- If WaitEvent is NULL, execution is in blocking mode. The BSP waits until all
- APs finish or TimeoutInMicroseconds expires. Otherwise, execution is in non-blocking
- mode, and the BSP returns from this service without waiting for APs. If a
- non-blocking mode is requested after the UEFI Event EFI_EVENT_GROUP_READY_TO_BOOT
- is signaled, then EFI_UNSUPPORTED must be returned.
-
- If the timeout specified by TimeoutInMicroseconds expires before all APs return
- from Procedure, then Procedure on the failed APs is terminated. All enabled APs
- are always available for further calls to EFI_MP_SERVICES_PROTOCOL.StartupAllAPs()
- and EFI_MP_SERVICES_PROTOCOL.StartupThisAP(). If FailedCpuList is not NULL, its
- content points to the list of processor handle numbers in which Procedure was
- terminated.
-
- Note: It is the responsibility of the consumer of the EFI_MP_SERVICES_PROTOCOL.StartupAllAPs()
- to make sure that the nature of the code that is executed on the BSP and the
- dispatched APs is well controlled. The MP Services Protocol does not guarantee
- that the Procedure function is MP-safe. Hence, the tasks that can be run in
- parallel are limited to certain independent tasks and well-controlled exclusive
- code. EFI services and protocols may not be called by APs unless otherwise
- specified.
-
- In blocking execution mode, BSP waits until all APs finish or
- TimeoutInMicroseconds expires.
-
- In non-blocking execution mode, BSP is freed to return to the caller and then
- proceed to the next task without having to wait for APs. The following
- sequence needs to occur in a non-blocking execution mode:
-
- -# The caller that intends to use this MP Services Protocol in non-blocking
- mode creates WaitEvent by calling the EFI CreateEvent() service. The caller
- invokes EFI_MP_SERVICES_PROTOCOL.StartupAllAPs(). If the parameter WaitEvent
- is not NULL, then StartupAllAPs() executes in non-blocking mode. It requests
- the function specified by Procedure to be started on all the enabled APs,
- and releases the BSP to continue with other tasks.
- -# The caller can use the CheckEvent() and WaitForEvent() services to check
- the state of the WaitEvent created in step 1.
- -# When the APs complete their task or TimeoutInMicroSecondss expires, the MP
- Service signals WaitEvent by calling the EFI SignalEvent() function. If
- FailedCpuList is not NULL, its content is available when WaitEvent is
- signaled. If all APs returned from Procedure prior to the timeout, then
- FailedCpuList is set to NULL. If not all APs return from Procedure before
- the timeout, then FailedCpuList is filled in with the list of the failed
- APs. The buffer is allocated by MP Service Protocol using AllocatePool().
- It is the caller's responsibility to free the buffer with FreePool() service.
- -# This invocation of SignalEvent() function informs the caller that invoked
- EFI_MP_SERVICES_PROTOCOL.StartupAllAPs() that either all the APs completed
- the specified task or a timeout occurred. The contents of FailedCpuList
- can be examined to determine which APs did not complete the specified task
- prior to the timeout.
-
- @param[in] This A pointer to the EFI_MP_SERVICES_PROTOCOL
- instance.
- @param[in] Procedure A pointer to the function to be run on
- enabled APs of the system. See type
- EFI_AP_PROCEDURE.
- @param[in] SingleThread If TRUE, then all the enabled APs execute
- the function specified by Procedure one by
- one, in ascending order of processor handle
- number. If FALSE, then all the enabled APs
- execute the function specified by Procedure
- simultaneously.
- @param[in] WaitEvent The event created by the caller with CreateEvent()
- service. If it is NULL, then execute in
- blocking mode. BSP waits until all APs finish
- or TimeoutInMicroseconds expires. If it's
- not NULL, then execute in non-blocking mode.
- BSP requests the function specified by
- Procedure to be started on all the enabled
- APs, and go on executing immediately. If
- all return from Procedure, or TimeoutInMicroseconds
- expires, this event is signaled. The BSP
- can use the CheckEvent() or WaitForEvent()
- services to check the state of event. Type
- EFI_EVENT is defined in CreateEvent() in
- the Unified Extensible Firmware Interface
- Specification.
- @param[in] TimeoutInMicroseconds Indicates the time limit in microseconds for
- APs to return from Procedure, either for
- blocking or non-blocking mode. Zero means
- infinity. If the timeout expires before
- all APs return from Procedure, then Procedure
- on the failed APs is terminated. All enabled
- APs are available for next function assigned
- by EFI_MP_SERVICES_PROTOCOL.StartupAllAPs()
- or EFI_MP_SERVICES_PROTOCOL.StartupThisAP().
- If the timeout expires in blocking mode,
- BSP returns EFI_TIMEOUT. If the timeout
- expires in non-blocking mode, WaitEvent
- is signaled with SignalEvent().
- @param[in] ProcedureArgument The parameter passed into Procedure for
- all APs.
- @param[out] FailedCpuList If NULL, this parameter is ignored. Otherwise,
- if all APs finish successfully, then its
- content is set to NULL. If not all APs
- finish before timeout expires, then its
- content is set to address of the buffer
- holding handle numbers of the failed APs.
- The buffer is allocated by MP Service Protocol,
- and it's the caller's responsibility to
- free the buffer with FreePool() service.
- In blocking mode, it is ready for consumption
- when the call returns. In non-blocking mode,
- it is ready when WaitEvent is signaled. The
- list of failed CPU is terminated by
- END_OF_CPU_LIST.

- @retval EFI_SUCCESS In blocking mode, all APs have finished before
