Abstract
An invention is disclosed that provides a mechanism for exposing to user mode applications the features and information enabled by the Advanced Configuration and Power Interface (“ACPI”) specification. The present invention provides a generic mapping driver that executes in kernel mode, and that makes calls to the ACPI driver accessible by user mode applications. The mapping driver may be a part of a management instrumentation system, such as the Windows Management Instrumentation (“WMI”) system. The WMI system provides an interface through which instrumented components, such as hardware devices, can provide information and notification to management applications in user mode through a consistent management information store. The mapping driver provides access to the ACPI system from the WMI management system.
