Maybe - but what sort of bookkeeping? i.e. What information does your PS want at endio time? [mpio->pgpath plus a success/failure flag?] How does this interact with what hw_handler is doing? The PS already gets called the first time there's a failure (fail_path). Is there a better interface? If this is purely statistical, would the functionality fit better elsewhere (e.g. counters in the core)? Alasdair -- agk@xxxxxxxxxx
