.Sh SYNOPSIS
.Cd "device firewire"
.Pp
.In dev/firewire/firewire.h
.Sh DESCRIPTION
.Fx
provides machine-independent bus support and row drivers for
.Tn firewire
interfaces.
.Pp
The
.Nm
driver consists of two layers: the controller and the
bus layer.
The controller attaches to a physical bus
(like
.Xr pci 4 ) .
The
.Tn firewire
bus attaches to the controller. And the additional driver can be
attached to the bus.
.Pp
Up to 63 devices, including the host itself, can be attached to
a firewire bus. The root node is dynamically assigned with PHY
device function. Also, the other firewire bus specific parameters
e.g. node id, cycle master, isochronous resource manager and bus
manager, are dynamically assigned, after bus rest is initiated.
On firewire bus, every device is identified with EUI 64 address.

$FreeBSD$
IEEE 1394 support for FreeBSD-5.X and 4.X.
1. Introduction
This tarball contains IEEE1394(FireWire) driver which is first
written by Katsushi Kobayashi[1] <ikob@koganei.wide.ad.jp> and
modified by Hidetoshi Shimokawa <simokawa@freebsd.org>.
Please note this driver is still under development.
You can find latest snapshots under:
http://people.freebsd.org/~simokawa/
named firewire-2002XXXX.tar.gz
The driver consists of 6 parts:
- fwohci.c/fwohci_pci.c
OHCI[2] driver
- IEEE1394 link/phy chip control
- firewire.c
Chip independent driver
- CSR
- Transaction
- Character devices for userland
- fwmem.c
/dev/fwmem0: physical memory of a remote node.
- sbp.c
SBP-II[3] (a.k.a. SCSI over FireWire) driver
- if_fwe.c
NON-Standard implementation of Ethernet over FireWire.
- bus_mgm.c (userland)
Bus management function for user.
show topology map, change gap count, bus reset, etc.
2. Installation
Suppose you have kernel source at /sys.
- Extract tarball at root directory.
- cd /sys/dev/firewire
- make
- make install
- make load
For FreeBSD-4 user:
- ./MAKEDEV
3. SBP-II support (sbp)
- You need CAM(SCSI) support in your kernel.
If you are using FreeBSD-5 before 2002/03/23 or FreeBSD-4 before
2002/4/8, you need to apply CAM-patch in this archive
to handle HDD's(T_RBC or T_DIRECT which doesn't support READ_6).
- If you connect a few firewire devices only, try the following to
reduce gap overhead.
- ./bus_mgm -g 8
4. Ethernet over FireWire (if_fwe)
This is a sample driver for ethernet emulation. Please note this
does NOT conform to any standards like IP over FireWire(RFC2734[4]).
It just sends ethernet frames encapsulated in asynchronous stream
packets. It doesn't scale because it does something like unicast over multicast, but it's easy to be implemented and you can use any
facilities what ethernet can do. (ipv6, bridging, vlan etc.)
It also has DEVICE_POLLING[5] support. To enable it, edit your
kernel config file and Makefile.fwe then rebuild kernel and if_fwe.ko.
Note this driver checks kern.polling.enable only when enabling the
interface. When you enable polling after the interface is up,
try 'ifconfig fwe0 down;ifconfig fwe0 up'.
5. FireWire for Kernel Hackers
As you know, IEEE1394 is a bus and OHCI supports physical access
to the host memory. This means that you can access the remote
host over firewire without software support at the remote host.
In other words, you can investigate remote host's physical memory
whether its OS is alive or crashed or hangs up.
You need to apply KVMLIB-patch and rebuild libkvm then rebuild ps,
dmesg and gdb those are statically linked.
You may want to apply GDB-patch in this archive to get same behavior
as gdb with /dev/mem or want to insert savectx(&dumppcb) into panic(),
breakpoint() and so on to emulation crash dump.
You have to determine target node_id manually at this point.
(guess using bus_mgm -t or dmesg)
(Targets should be specified by EUI64 in the future)
# sysctl kern.firewire.fwmem_node=[node_id]
# ps -agx -M /dev/fwmem0 -N /sys/i386/compile/GENERIC/kernel
# dmesg -M /dev/fwmem0 -N /sys/i386/compile/GENERIC/kernel
# gdb -k -c /dev/fwmem0 /sys/i386/compile/GENERIC/kernel.debug
# dd if=/dev/fwmem0 of=vmcore bs=1m count=[phys. memory in MB]
remote gdb at 400,000,000 bps :-)
6. DV
I have not tested yet.
7. Tested HW
OS
- FreeBSD-4/i386
- FreeBSD-4/alpha
- FreeBSD-5/i386
* Not tested on SMP.
* Not tested on big-endian machine...
OHCI
- Texas Instruments TSB12LV26 (PCI)
- Texas Instruments TSB43AA22 (PCI/Cardbus)
* There might be phy probing problem but most of the OHCI
chips should work.
* Tested with multiple firewire buses.
SBP-II
- HDD: Logitec USB/FireWire LHD-P30FU
- HDD: Yano A-dish 120GB
- HDD: Yano B-Max 320GB
The repository of cvsup2.jp.freebsd.org is on this device.
- HDD: Personal Storage 3000XT 160GB
The last sector of this drive cannot be accessed..
- DVD-RAM: Panasonic LF-D340JD
- SCSI-FireWire converter: Yano FWSCSI-01
We can recognize only 1 device/lun at this point
- HDD: iPod, PowerBook G4 (target mode)
Reported by ikob
- Scanner: Epson GT-9700F
Now works!!
Sane-backend needs a patch(SANE-patch in this archive).
if_fwe
- IPv4, IPv6, bridging, vlan.
- You need at least two FreeBSD machines with this driver to use.
