WebMar 17, 2023 · Supporting ACPI Devices. This section describes how a vendor can use a WDM function driver in Windows to enhance the functionality of an Advanced Configuration and Power Interface (ACPI) device. ACPI devices include low-level system devices such as batteries, thermal zones, and other devices defined in a system's ACPI namespace.
WebACPI can best be described as a framework of concepts and interfaces that are implemented to form a subsystem within the host OS. The ACPI tables, handlers, interpreter, namespace, events, and interrupt model together form this implementation of ACPI, creating the ACPI subsystem within the host OS.
