The Platform Communication Channel Table (PCCT) generator collates the relevant information required for generating a PCCT table from configuration manager using the configuration manager protocol. The DynamicTablesManager then install the PCCT table. From ACPI 6.4, s14 PLATFORM COMMUNICATIONS CHANNEL (PCC): The platform communication channel (PCC) is a generic mechanism for OSPM to communicate with an entity in the platform.

 | |
| 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.
 | |
|   - 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.
 | |
|   - SSDT Cpu-Topology:
 | |
|             The SSDT Cpu-Topology generator collates the cpu and LPI
 | |
|             information from the Configuration Manager and generates a
 | |
|             SSDT table describing the CPU hierarchy.
 | |
|   - SSDT Pci-Express:
 | |
|             The SSDT Pci Express generator collates the Pci Express
 | |
|             information from the Configuration Manager and generates a
 | |
|             SSDT table describing a Pci Express bus.
