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?
