use to synchornize and protect all data objects that are used for that
SIM. Drivers that are not yet MPSAFE register Giant and operate as
usual. RIght now, no drivers are MPSAFE, though a few will be changed
in the coming week as this work settles down.
The driver API has changed, so all CAM drivers will need to be recompiled.
The userland API has not changed, so tools like camcontrol do not need to
be recompiled.

- Compatibility for RELENG_4 and DragonFly.
* firewire
- Timestamp just before queuing.
- Retry bus probe if it fails.
- Use device_printf() for debug message.
- Invalidiate CROM while update.
- Don't process minimum/invalid CROM.
* sbp
- Add ORB_SHORTAGE flag.
- Add sbp.tags tunable.
- Revive doorbell support. It's not enabled by default.
Though this is still incomplete and has some missing features such as
exclusive login and event notification, it may be enough for someone
who wants to play with it.
This driver is supposed to work with firewire(4), targ(4) of CAM(4)
and scsi_target(8) which can be found in /usr/share/example/scsi_target.
This driver doesn't require sbp(4) which implements initiator mode.
Sample configuration:
Kernel: (you can use modules as well)
device firewire
device scbus
device targ
device sbp_targ
After reboot:
# mdconfig -a -t malloc -s 10m
md0
# scsi_target 0:0:0 /dev/md0
(Assuming sbp_targ0 on scbus0)
You should find the 10MB HDD on FreeBSD/MacOS X/WinXP or whatever connected
to the target using FireWire.
Manpage is not finished yet.
