it could be that i misunderstood the op's point. what i understood from the original post was a scheme was envisioned where a user process would poll a status file to get interrupt status. if i understood this correctly, then providing an interrupt file that returns even 0 bytes when there's an interrupt would be an alternative providing interrupt semantics to the up. there are some bits to work out if the user process falls behind, but it's no different than a network device. does that answer your question? - erik
