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.
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.
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. To compile this driver as a module, say M here: The module will be called firewire-net.
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). 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.
