There are a number of issues here for anyone trying to use this today:
1. On my test drive the command engine on the drive seems to stall after the
inquire is done. So the mode sense times out for a long time before
aborting. This obviously needs to be tracked down and fixed.
However it does do a proper inquire:
scsibus0 at sbpscsi0: 1 target, 1 lun per target
sd0 at scsibus0 target 0 lun 0: <Maxtor, 1394 storage, 60> disk fixed
2. This code is quite ugly in places as debug code was added to test things.
Definitly needs cleanup/documention in places where it's using command
structures. The structure for alloc'ing orbs, running them through the
command engine and getting state back is mostly set but implementation needs
an overhaul in places.
3. For testing I use the following config options:
fwohci* at cardbus? dev ? function ? # IEEE1394 Controller
fw* at fwbus?
options FW_DEBUG
options FWNODE_DEBUG
options P1212_DEBUG
options SBP2_DEBUG
options SBPSCSI_DEBUG
fwnode* at fwbus?
sbpscsi* at fwnode?
scsibus* at sbpscsi?
Current status:
Only OHCI chip is supported (fwohci).
ping (IPv4) works with Sony's implementation (SmartConnect) on Win98.
sometimes works but not stable.
Not implemented yet:
IRM (Isochronous Resource Manager) functionality.
Link layer fragmentation.
Topology map.
More to do:
clean ups
MCAP
charactor device part
dhcp
There is no entry in GENERIC config file yet.
Follow sys/dev/ieee1394/IMPLEMENTATION to enable if_fw.
