The Dynamic Tables Framework provisions two classes of ACPI table
|
|
generators.
|
|
- Standard generators: The ACPI table generators implemented by the
|
|
Dynamic Tables Framework.
|
|
- OEM generators: The ACPI table generators customized by the OEM.
|
|
|
|
The Dynamic Tables Framework implements the following ACPI table generators:
|
|
- RAW : This is the simplest ACPI table generator. It simply installs
|
|
the ACPI table provided in the AcpiTableData member of the
|
|
CM_STD_OBJ_ACPI_TABLE_INFO. The ACPI table data is provided by
|
|
the Configuration Manager and is generated using an implementation
|
|
defined mechanism.
|
|
- DSDT : The DSDT generator is a clone of the RAW generator. The difference
|
|
is in the way the ACPI Table Data is generated from an AML file.
|
|
- SSDT : The SSDT generator is a clone of the RAW generator. 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.
