Expose a sysfs identifier encapsulating the CMN part number and revision so that jevents can narrow down a fundamental set of possible events for calculating metrics. Configuration-dependent aspects - such as whether a given node type is present, and/or a given node ID is valid - are still not covered, and in general it's hard to see how userspace could handle them, so we won't be removing any data or validation logic from the driver any time soon, but at least it's a step in a useful direction.
