Stefan Richter 0c53decdd0 firewire: new stack is no longer experimental
The new stack is now recommended over the old one if used for industrial
video (IIDC/DCAM) or for storage devices (SBP-2) due to better
performance, improved compatibility, added features, and security.  It
should also be functionally on par with and is more secure than the old
ieee1394 stack in the use case of consumer video devices.

IP-over-1394 support for the new stack is currently emerging, and a
backend of the firedtv DVB driver to the new stack should be available
soon.

The one remaining area where the old stack is still required are audio
devices, as the new stack is not yet able to support the FFADO FireWire
audio framework.

help
This is the new-generation IEEE 1394 (FireWire) driver stack
a.k.a. Juju, a new implementation designed for robustness and
simplicity.
See http://ieee1394.wiki.kernel.org/index.php/Juju_Migration
for information about migration from the older Linux 1394 stack
to the new driver stack.
To compile this driver as a module, say M here: the module will be
called firewire-core.
This module functionally replaces ieee1394, raw1394, and video1394.
To access it from application programs, you generally need at least
libraw1394 v2. IIDC/DCAM applications need libdc1394 v2.
No libraries are required to access storage devices through the
firewire-sbp2 driver.
NOTE:
FireWire audio devices currently require the old drivers (ieee1394,
ohci1394, raw1394).
config FIREWIRE_OHCI
tristate "OHCI-1394 controllers"
depends on PCI && FIREWIRE
help
Enable this driver if you have a FireWire controller based
on the OHCI specification. For all practical purposes, this
is the only chipset in use, so say Y here.
To compile this driver as a module, say M here: The module will be
called firewire-ohci. It replaces ohci1394 of the classic IEEE 1394
stack.
NOTE:
If you want to install firewire-ohci and ohci1394 together, you
should configure them only as modules and blacklist the driver(s)
which you don't want to have auto-loaded. Add either
blacklist firewire-ohci
or
blacklist ohci1394
blacklist video1394
blacklist dv1394
to /etc/modprobe.conf or /etc/modprobe.d/* and update modprobe.conf
depending on your distribution.
config FIREWIRE_OHCI_DEBUG
bool
depends on FIREWIRE_OHCI
default y
config FIREWIRE_SBP2
tristate "Storage devices (SBP-2 protocol)"
depends on FIREWIRE && SCSI
help
This option enables you to use SBP-2 devices connected to a
FireWire bus. SBP-2 devices include storage devices like
harddisks and DVD drives, also some other FireWire devices
like scanners.
To compile this driver as a module, say M here: The module will be
called firewire-sbp2. It replaces sbp2 of the classic IEEE 1394
stack.
You should also enable support for disks, CD-ROMs, etc. in the SCSI
configuration section.
config FIREWIRE_NET
tristate "IP networking over 1394 (EXPERIMENTAL)"
depends on FIREWIRE && INET && EXPERIMENTAL
help
This enables IPv4 over IEEE 1394, providing IP connectivity with
other implementations of RFC 2734 as found on several operating
systems. Multicast support is currently limited.
NOTE, this driver is not stable yet!
To compile this driver as a module, say M here: The module will be
called firewire-net. It replaces eth1394 of the classic IEEE 1394
stack.
