The SelfI-ID is one type of DMAs defined in 1394 OHCI specification. It is operated by two registers, one interrupt, and has one format of buffer. This commit adds some static inline functions to deserialize the data in the buffer and registers. Some KUnit tests are also added to check their reliability.

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.docs.kernel.org/en/latest/migration.html
|
|
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

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.

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).
|
|
|
|
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.
