The difference + is in the way the ACPI Table Data is generated from an AML file. + - FADT : The FADT generator collates the required platform information from + the Configuration Manager and builds the FADT table. + - MADT : The MADT generator collates the GIC information from the + Configuration Manager and builds the MADT table. + - GTDT : The GTDT generator collates the Timer information from the + Configuration Manager and builds the GTDT table. + - DBG2 : The DBG2 generator collates the debug serial port information from + the Configuration Manager and builds the DBG2 table. + - SPCR : The SPCR generator collates the serial port information from the + Configuration Manager and builds the SPCR table. + - MCFG : The MCFG generator collates the PCI configuration space information + from the Configuration Manager and builds the MCFG table. + - IORT : The IORT generator collates the IO Topology information from the + Configuration Manager and builds the IORT table. + - PPTT : The PPTT generator collates the processor topology information from + the Configuration Manager and builds the PPTT table. + - SRAT : The SRAT generator collates the system resource affinity information + from the Configuration Manager and builds the SRAT table. + - SSDT Serial-Port: + The SSDT Serial generator collates the Serial port information + from the Configuration Manager and patches the SSDT Serial Port + template to build the SSDT Serial port table. + - SSDT CMN-600: + The SSDT CMN-600 generator collates the CMN-600 information + from the Configuration Manager and patches the SSDT CMN-600 + template to build the SSDT CMN-600 table. +*/ + +/** The ACPI_TABLE_GENERATOR_ID type describes ACPI table generator ID. +*/ +typedef TABLE_GENERATOR_ID ACPI_TABLE_GENERATOR_ID;
