MpServicesUnitTestGetNumberOfProcessors()

EFI_STATUS MpServicesUnitTestGetNumberOfProcessors	(	IN MP_SERVICES	MpServices,
		OUT UINTN *	NumberOfProcessors,
		OUT UINTN *	NumberOfEnabledProcessors
	)

Retrieve the number of logical processor in the platform and the number of those logical processors that are enabled on this boot.

Parameters

[in]	MpServices	MP_SERVICES structure.
[out]	NumberOfProcessors	Pointer to the total number of logical processors in the system, including the BSP and disabled APs.
[out]	NumberOfEnabledProcessors	Pointer to the number of processors in the system that are enabled.

MpServicesUnitTestStartupAllAPs()

EFI_STATUS MpServicesUnitTestStartupAllAPs	(	IN MP_SERVICES	MpServices,
		IN EFI_AP_PROCEDURE	Procedure,
		IN BOOLEAN	SingleThread,
		IN UINTN	TimeoutInMicroSeconds,
		IN VOID *	ProcedureArgument
	)

Execute a caller provided function on all enabled APs.

Parameters

[in]	MpServices	MP_SERVICES structure.
[in]	Procedure	Pointer to the function to be run on enabled APs of the system.
[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.
[in]	TimeoutInMicroSeconds	Indicates the time limit in microseconds for APs to return from Procedure, for blocking mode only. Zero means infinity.
[in]	ProcedureArgument	The parameter passed into Procedure for all APs.

Return values

EFI_SUCCESS	Execute a caller provided function on all enabled APs successfully
Others	Execute a caller provided function on all enabled APs unsuccessfully

Parameters

[in]	MpServices	MP_SERVICES structure.
[in]	Procedure	Pointer to the function to be run on enabled APs of the system.
[in]	ProcessorNumber	The handle number of the AP.
[in]	TimeoutInMicroSeconds	Indicates the time limit in microseconds for APs to return from Procedure, for blocking mode only. Zero means infinity.
[in]	ProcedureArgument	The parameter passed into Procedure for all APs.

Return values

EFI_SUCCESS	Caller gets one enabled AP to execute a caller-provided function successfully
Others	Caller gets one enabled AP to execute a caller-provided function unsuccessfully
