Hi there,
I've just bought Roland FA-101 external firewire audio interface box to
start experimenting with multichannel sound processing on my FreeBSD
laptop (NEC Versa S950). 7.2-STABLE runs quite nicely on it, and sees
FW host controller (per pciconf -lv):
fwohci0@pci0:6:7:2: class=0x0c0010 card=0x83191033 chip=0x8032104c rev=0x00 hdr=0x00
vendor = 'Texas Instruments (TI)'
device = 'OHCI Compliant IEEE-1394 FireWire Controller'
class = serial bus
subclass = FireWire
My intention (and ultimate goal for now) is to port ffado.org project
code to our beloved FreeBSD. However, after I kldload firewire.ko and
connect FA-101, I see the following in dmesg:
fwohci0: <1394 Open Host Controller Interface> mem
0xb0117000-0xb01177ff,0xb0110000-0xb0113fff irq 18 at device 7.2 on pci6

firewire0: 2 nodes, maxhop <= 1, cable IRM = 0 (me)
firewire0: root node is not cycle master capable
firewire0: bus manager 0 (me)
fwohci0: too many cycle lost, no cycle master presents?
fwohci0: txd err= 3 miss Ack err
fwohci0: txd err= 3 miss Ack err
fwohci0: txd err= 3 miss Ack err
These messages do not look very exciting, and apparently my box does not
see the device afterwards:
# fwcontrol -t

00 1 5 S400 0 1 0W - - 1 0
I've tried several things; e.g. setting gapcount to 8, but fwcontrol -t
shows the following lines for couple of seconds, and than it disappears
(rapid repeat of fwcontrol -t command output below):
# fwcontrol -t

I've been browsing through fbsd-fw@ archives tonight and discovered
several patches by sbruno@ that might address [some of the] issues I'm
seeing. Sean (and anyone else, of course), can you give me some hand on
the subject? I'm happy to provide any debug info, glad to test patches,
etc. Root access to my laptop is also quite possible, shall it be needed.
Thanks.
