[in]	CfgMgrProtocol	Pointer to the Configuration Manager Protocol Interface.
[in]	Srat	Pointer to the SRAT Table.

Return values

EFI_SUCCESS

Table generated successfully.

Add the arch specific sub-tables to the SRAT table.

These sub-tables are written in the space reserved beforehand.

Parameters

[in]	CfgMgrProtocol	Pointer to the Configuration Manager Protocol Interface.

ArchReserveOffsets()

EFI_STATUS EFIAPI ArchReserveOffsets	(	IN CONST EDKII_CONFIGURATION_MANAGER_PROTOCOL *CONST	CfgMgrProtocol,
		IN OUT UINT32 *	ArchOffset
	)

Reserve arch sub-tables space.

Parameters

[in]	CfgMgrProtocol	Pointer to the Configuration Manager
[in,out]	ArchOffset	On input, contains the offset where arch specific sub-tables can be written. It is expected that there enough space to write all the arch specific sub-tables from this offset onward. On ouput, contains the ending offset of the arch specific sub-tables.

Return values

EFI_SUCCESS	Table generated successfully.
EFI_INVALID_PARAMETER	A parameter is invalid.
EFI_NOT_FOUND	The required object information is not found.
EFI_BAD_BUFFER_SIZE	The size returned by the Configuration Manager is less than the Object size for the requested object.

Reserve arch sub-tables space.

Parameters

[in]	CfgMgrProtocol	Pointer to the Configuration Manager
[in,out]	ArchOffset	On input, contains the offset where arch specific sub-tables can be written. It is expected that there enough space to write all the arch specific sub-tables from this offset onward. On ouput, contains the ending offset of the arch specific sub-tables.

Return values

EFI_SUCCESS	Table generated successfully.
EFI_UNSUPPORTED	Not supported.
EFI_INVALID_PARAMETER	A parameter is invalid.
EFI_NOT_FOUND	The required object information is not found.
EFI_BAD_BUFFER_SIZE	The size returned by the Configuration Manager is less than the Object size for the requested object.
