Hello, Context: HDLC PCI adapter + line at 2 Mb/s + external traffic generator that fills the line with 5 to x1000 bytes frame. I want to see how my code bahaves during rare (?) events: an overflow of the RX fifo (256 bytes) and a TX underrun. It's my understanding that if the adapter pains at DMAing, those errors should be triggered. Could I/O at a inocuous location (a well-choosen PCI register ?) be enough for that ? -- Ueimor - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
