System and method for accessing information made available by a kernel mode driver
First Claim
1. A computing system having an operating environment with at least two operational modes for interfacing a user application to a system component, the system comprising:
- a processor;
a system memory;
at least one system component; and
wherein the computing system is configured to provide;
a management module operating in a first operational mode that, in response to an instruction from an external application operating in the first operational mode, issues a first interface message to the system component; and
a translation module operating in a second operational mode, communicatively coupled to the system component, and further communicatively coupled to the management module, that receives the first interface message from the management module, translates information in the first interface message to create a second interface message, and issues the second interface message to the system component.

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.
