5.6.8 Predefined ACPI Names for Objects, Methods, and Resources
The following table summarizes the predefined names for the ACPI namespace objects, control
methods, and resource descriptor fields defined in this specification. Provided for each name is a
short description and a reference to the section number and page number of the actual definition of
the name. ACPI names that are predefined by other specifications are also listed along with their
corresponding specification reference.
Note: All names that begin with an underscore are reserved for ACPI use only
