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.
config FIREWIRE_OHCI
tristate "OHCI-1394 controllers"
firewire: ohci: Asynchronous Reception rewrite Move the AR DMA descriptors out of the buffer pages, and map the buffer pages linearly into the kernel's address space. This allows the driver to ignore any page boundaries in the DMA data and thus to avoid any copying around of packet payloads. This fixes the bug where S800 packets that are so big (> 4080 bytes) that they can be split over three pages were not handled correctly. Due to the changed algorithm, we can now use arbitrarily many buffer pages, which improves performance because the controller can more easily unload its DMA FIFO. Furthermore, using streaming DMA mappings should improve perfomance on architectures where coherent DMA mappings are not cacheable. Even on other architectures, the caching behaviour should be improved slightly because the CPU no longer writes to the buffer pages. v2: Detect the last filled buffer page by searching the descriptor's residual count value fields in order (like in the old code), instead of going backwards through the transfer status fields; it looks as if some controllers do not set the latter correctly. v3: Fix an old resume bug that would now make the handler run into a BUG_ON, and replace that check with more useful error handling. Increase the buffer size for better performance with non-TI chips. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Maxim Levitsky writes: Works almost perfectly. I can still see RCODE_BUSY errors sometimes, not very often though. 64K here eliminates these errors completely. This is most likely due to nouveau drivers and lowest perf level I use to lower card temperature. That increases latencies too much I think. Besides that the IO is just perfect.

depends on PCI && FIREWIRE && MMU
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.
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.
You should also enable support for disks, CD-ROMs, etc. in the SCSI
configuration section.
config FIREWIRE_NET
tristate "IP networking over 1394"
depends on FIREWIRE && INET
help
This enables IPv4/IPv6 over IEEE 1394, providing IP connectivity
with other implementations of RFC 2734/3146 as found on several
operating systems. Multicast support is currently limited.
To compile this driver as a module, say M here: The module will be
called firewire-net.
firewire: new driver: nosy - IEEE 1394 traffic sniffer This adds the traffic sniffer driver for Texas Instruments PCILynx/ PCILynx2 based cards.

Known contributers are Jody McIntyre and Jonathan Woithe. Nosy programs PCILynx chips to operate in promiscuous mode, which is a feature that is not found in OHCI-1394 controllers. Hence, only special hardware as mentioned in the Kconfig help text is suitable for nosy. This is only the kernelspace part of nosy. There is a userspace interface to it, called nosy-dump, proposed to be added into the tools/ subdirectory of the kernel sources in a subsequent change.

help
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 and G4 with PCI graphics
(onboard controller).
