> Hi, > > I would start by taking a look at the way that you are handling > dma time outs or errors. timeout is simple since you don't get the interrupt and the application remains blocked or the close routine times out. for "errors" i don't have any explicit check for non-pnp cards (except for SB16) since there is no general way to ask the board how the jumpers are wired. And for PnP boards no check should be necessary since the resources are read from the pnp configuration. In any case i think the problem boils down to understanding what happens if i have a 8237 channel programmed for I/O reads (i.e. sample audio), and am sending i/o write requests (play audio) instead. cheers luigi -----------------------------+-------------------------------------- Luigi Rizzo | Dip. di Ingegneria dell'Informazione email: luigi@iet.unipi.it | Universita' di Pisa tel: +39-50-568533 | via Diotisalvi 2, 56126 PISA (Italy) fax: +39-50-568522 | http://www.iet.unipi.it/~luigi/ _____________________________|______________________________________ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
