The Generic ACPI for Arm Components 1.0 Platform Design
Document, s2.6.4 "ASL code examples" provides information
to describe an Arm CoreLink CMN-600 Coherent Mesh Network
using an ASL definition block table.
The SSDT CMN-600 Table Generator uses the Configuration
Manager protocol to obtain the following information about
the CMN-600 device on the platform:
- the PERIPHBASE address location and address range;
- the ROOTNODEBASE address location;
- the number of Debug and Trace Controller (DTC)
and their respective interrupt number;
The CMN-600 mesh is described using the CM_ARM_CMN_600_INFO
and CM_ARM_EXTENDED_INTERRUPT structures in the Configuration
Manager.
The SSDT CMN-600 Table generator:
- gets the CMN-600 hardware information
from the configuration manager.
- uses the AmlLib interfaces to parse the AML
template BLOB and construct an AML tree.
- uses the AmlLib to update:
- the "_UID" value;
- the address location and range of the PERIPHBASE;
- the address location of the ROOTNODEBASE;
- the number of Debug and Trace Controller (DTC)
and their respective interrupt number;
- serializes the AML tree to an output buffer.
This output buffer contains the fixed-up AML code,
which is then installed as an ACPI SSDT table.
