Patent ID: 7114064

Claim:
A system for accessing an Advanced Configuration and Power Interface (ACPI) namespace nodal tree in a computer platform employing an ACPI-compatible implementation, comprising: a namespace data structure operably associated with said computer platform, said namespace data structure having said ACPI namespace nodal tree with at least one node; an index data structure operably associated with said computer platform, said index data structure including at least one pointer pointing to an index node that spans a sub-tree of said ACPI namespace nodal tree, wherein said ACPI namespace nodal tree remains unmodified; and a traversing function operable to commence a searching operation responsive to a namespace object request with respect to a node in said ACPI namespace nodal tree, wherein said traversing function commences said searching operation from an intermediary index node instead of starting from a root node of said ACPI namespace nodal tree, said intermediary index node being pointed to by a pointer obtained from searching said index data structure.
