The drivers - ohci1394 (controller driver) - ieee1394 (core) - dv1394, raw1394, video1394 (userspace ABI) - eth1394, sbp2 (protocol drivers) are replaced by - firewire-ohci (controller driver) - firewire-core (core and userspace ABI) - firewire-net, firewire-sbp2 (protocol drivers) which are more featureful, better performing, and more secure than the older drivers; all with a smaller and more modern code base. The driver firedtv in drivers/media/dvb/firewire/ contains backends to both ieee1394 and firewire-core. Its ieee1394 backend code can be removed in an independent commit; firedtv as-is builds and works fine without ieee1394. The driver pcilynx (an incomplete controller driver) is deleted without replacement since PCILynx cards are extremely rare. Owners of these cards use them with the stand-alone bus sniffer driver nosy instead. The drivers nosy and init_ohci1394_dma which do not interact with either of the two IEEE 1394 stacks are not affected by the ieee1394 subsystem removal. There are still some issues with the newer firewire subsystem compared to the older one: - The rare and quirky controllers ALi M52xx, Apple UniNorth v1, NVIDIA NForce2 are even less well supported by firewire-ohci than by ohci1394. I am looking into the M52xx issue. - The experimental firewire-net is reportedly less stable than its experimental cousin eth1394. - Audio playback of a certain group of audio devices (ones based on DICE chipset with EAP; supported by prerelease FFADO code) does not work yet. This issue is still under investigation. - There were some ieee1394 based out-of-the-mainline drivers. Of them, only lisight, an audio driver for iSight webcams, seems still useful. Work is underway to reimplement it on top of firewire-core. All these remainig issues are minor; they should not stand in the way of overall better user experience of IEEE 1394 on Linux, together with a reduction in support efforts and maintenance burden. The coexistence of two IEEE 1394 kernel driver stacks in the mainline since 2.6.22 shall end now, as announced earlier this year. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

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

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.

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.

You should also enable support for disks, CD-ROMs, etc. in the SCSI
|
|
configuration section.

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!

|
|
Nosy is an IEEE 1394 packet sniffer that is used for protocol
|
|
analysis and in development of IEEE 1394 drivers, applications,
|
|
or firmwares.
|
|
|
|
This driver lets you use a Texas Instruments PCILynx 1394 to PCI
|
|
link layer controller TSB12LV21/A/B as a low-budget bus analyzer.
|
|
PCILynx is a nowadays very rare IEEE 1394 controller which is
|
|
not OHCI 1394 compliant.
|
|
|
|
The following cards are known to be based on PCILynx or PCILynx-2:
|
|
IOI IOI-1394TT (PCI card), Unibrain Fireboard 400 PCI Lynx-2
|
|
(PCI card), Newer Technology FireWire 2 Go (CardBus card),
|
|
Apple Power Mac G3 blue & white (onboard controller).
|
|
|
|
To compile this driver as a module, say M here: The module will be
|
|
called nosy. Source code of a userspace interface to nosy, called
|
|
nosy-dump, can be found in tools/firewire/ of the kernel sources.
|
|
|
|
If unsure, say N.
