ACPI name space validation
First Claim
1. A computer-performed method of validating a power management command prior to executing the power management command, comprising:
- intercepting from a power management driver module the power management command;
testing the power management command in a test name space prior to performing the power management command in a second name space; and
generating an output based on a comparison of a first result obtained from testing the power management command in the test name space and a second result obtained from performing the power management command in the second name space.

Abstract
A method and system for passively validating an advanced configuration and power interface (ACPI) name space are provided. A filter driver may be adapted for use as a verification tool that intercepts requests by the ACPI driver to evaluate objects in the ACPI name space. Prior to the ACPI driver evaluating the object in the ACPI name space, the verification tool validates the object by looking up and validating a corresponding object in a test name space created from the ACPI name space. When the object validates, control is returned to the ACPI driver. When the object does not validate, the verification tool may either log the error to a log file, initiate a debugger to fix the problem, or both.

10. A data structure stored on one or more computer readable media, said data structure comprising:
-
a first data field storing an ACPI name space; a second data field storing a test name space corresponding to the ACPI name space, wherein the second data field comprises a duplication of the first data field; and a third data field storing a test case to be executed in the test name space upon interception of an ACPI command to be executed in the ACPI name space. - View Dependent Claims (11, 12)

13. A computer readable medium storing computer readable instructions that, when executed, perform a method of validating a computer power management command, said method comprising:
-
creating a second name space by copying entries from a first name space; intercepting the computer power management command from a driver module prior to execution of the computer power management command; obtaining at least one test case associated with the computer power management command; conducting the at least one test case on the second name space; performing the computer power management command on the first name space; and selectively indicating an error in the performance of the computer power management command in response to a comparison of a first result from conducting the at least one test with a second result from performing the computer power management command. - View Dependent Claims (14, 15, 16, 17, 18, 19)
