Advanced Configuration and Power Interface Specification

Introduction
1.9.2 Programming Models
Sections 4 and 5 define the ACPI hardware and software programming models. This part of the
specification is primarily for system designers, developers, and project managers.
All of the implementation-oriented, reference, and platform example sections of the specification
that follow (all the rest of the sections of the specification) are based on the models defined in
sections 4 and 5. These sections are the heart of the ACPI specification. There are extensive crossreferences
between the two sections.
Section 4: ACPI Hardware Specification.
Defines a set of hardware interfaces that meet the goals of this specification.
Section 5: ACPI Software Programming Model.
Defines a set of software interfaces that meet the goals of this specification.
1.9.3 Implementation Details
The third part of the specification defines the implementation details necessary to actually build
components that work on an ACPI-compatible platform. This part of the specification is primarily
for developers.
Section 6: Configuration.
Defines the reserved Plug and Play objects used to configure and assign resources to
devices, and share resources and the reserved objects used to track device insertion
and removal. Also defines the format of ACPI-compatible resource descriptors.
Section 7: Power and Performance Management.
Defines the reserved device power-management objects and the reserved-system
power-management objects.
Section 8: Processor Configuration and Control.
Defines how the OS manages the processors’ power consumption and other controls
while the system is in the working state.
Section 9: ACPI-Specific Device Objects.
Lists the integrated devices that need support for some device-specific ACPI controls,
along with the device-specific ACPI controls that can be provided. Most device
objects are controlled through generic objects and control methods and have generic
device IDs; this section discusses the exceptions.
Section 10: Power Source Devices.
Defines the reserved battery device and AC adapter objects.
Section 11: Thermal Management.
Defines the reserved thermal management objects.
Section 12: ACPI Embedded Controller Interface Specification.
Defines the interfaces between an ACPI-compatible OS and an embedded controller.
