This protocol provides some basic services to support publishing ACPI system tables. The
|
|
services handle many of the more mundane tasks that are required to publish a set of tables. The
|
|
services will:
|
|
- Generate common tables.
|
|
- Update the table links.
|
|
- Ensure that tables are properly aligned and use correct types of memory.
|
|
- Update checksum values and IDs.
|
|
- Complete the final installation of the tables.
