Hi I am trying to send DV stream from one PC to another using firewire bus: box1# egrep firew\|fwohci /var/log/messages | cut -d\ -f6- fwohci0: <Ricoh R5C551> mem 0xd0202000-0xd02027ff at device 5.1 on pci2 fwohci0: [GIANT-LOCKED] fwohci0: OHCI version 1.0 (ROM=1) fwohci0: No. of Isochronous channels is 4. fwohci0: EUI64 08:00:46:03:01:8d:e0:3c fwohci0: Phy 1394a available S400, 2 ports. fwohci0: Link S400, max_rec 2048 bytes. firewire0: <IEEE1394(FireWire) bus> on fwohci0 sbp0: <SBP-2/SCSI over FireWire> on firewire0 ... box1# fwcontrol -t crc_len: 4 generation:11 node_count:2 sid_count:2 id link gap_cnt speed delay cIRM power port0 port1 port2 ini more 00 1 5 S400 0 1 0W - P 0 0 01 1 5 S400 0 1 15W - - C 1 0 box1# fwcontrol -S sample.dv PAL 0123456789012345678901234 5678901234567890123456789 0123456789012345678901234 5678901234567890123456789 .... box2# fwcontrol -R gotsample.dv (EAGAIN) (EAGAIN) (EAGAIN) NTSC 0fwcontrol: unknown format 0x29 box2# egrep firew\|fwohci /var/log/messages | cut -d\ -f6- fwohci0: <Texas Instruments TSB12LV26> mem 0xe9100000-0xe9103fff,0xe9106000-0xe91067ff irq 12 at device 17.0 on pci0 fwohci0: [GIANT-LOCKED] fwohci0: OHCI version 1.0 (ROM=1) fwohci0: No. of Isochronous channel is 4. fwohci0: EUI64 00:30:8d:01:20:43:42:d8 fwohci0: Phy 1394a available S400, 3 ports. fwohci0: Link S400, max_rec 2048 bytes. firewire0: <IEEE1394(FireWire) bus> on fwohci0 What's wrong with such transfer ? (In reality both host are able to get stream from DV camera, and I can't send stream to camera back, not sure why, camera are DV-IN capable) Another question: Is there easy way to "export" disk device through firewire bus ? I do not mean NFS over fwe, I mean sbp or something on geom level. -- Vladimir B. Grebenschikov SWsoft Inc. vova@sw-soft.com
