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.
