That seems like it's something different: it's asking "has some other bit of QEMU registered a handler for this ioport?", not "at this moment in time if I make an I/O access will it succeed?" (which in principle should actually go all the way through and call a registered ioport handler which might then say "no, for this specific access we will fail"). thanks -- PMM
