GetBistInfoFromPpi()

EFI_STATUS GetBistInfoFromPpi	(	IN CONST EFI_PEI_SERVICES **	PeiServices,
		IN CONST EFI_GUID *	Guid,
		OUT EFI_PEI_PPI_DESCRIPTOR **	PpiDescriptor,
		OUT VOID **	BistInformationData,
		OUT UINT64 *BistInformationSize	OPTIONAL
	)

Worker function to get CPUs' BIST by calling SecPlatformInformationPpi or SecPlatformInformation2Ppi.

Parameters

PeiServices	Pointer to PEI Services Table
Guid	PPI Guid
PpiDescriptor	Return a pointer to instance of the EFI_PEI_PPI_DESCRIPTOR
BistInformationData	Pointer to BIST information data
BistInformationSize	Return the size in bytes of BIST information

Return values

SecPlatformInformation2()

EFI_STATUS EFIAPI SecPlatformInformation2	(	IN CONST EFI_PEI_SERVICES **	PeiServices,
		IN OUT UINT64 *	StructureSize,
		OUT EFI_SEC_PLATFORM_INFORMATION_RECORD2 *	PlatformInformationRecord2
	)

Implementation of the PlatformInformation2 service in EFI_SEC_PLATFORM_INFORMATION2_PPI.

Parameters

PeiServices	The pointer to the PEI Services Table.
StructureSize	The pointer to the variable describing size of the input buffer.
PlatformInformationRecord2	The pointer to the EFI_SEC_PLATFORM_INFORMATION_RECORD2.

Return values
