Update the Kconfig help texts of both stacks to encourage a general move from the older to the newer drivers. However, do not label ieee1394 as "Obsolete" yet, as the newer drivers have not been deployed as default stack in the majority of Linux distributions yet, and those who start doing so now may still want to install the old drivers as fallback for unforeseen issues. Since Linux 2.6.32, FireWire audio devices can be driven by the newer firewire driver stack too, hence remove an outdated comment about audio devices. Also remove comments about library versions since the 2nd generation of libraw1394 and libdc1394 is now in common use; details on library versions can be read at the wiki link from the help texts.

IEEE 1394 describes a high performance serial bus, which is also
|
|
known as FireWire(tm) or i.Link(tm) and is used for connecting all
|
|
sorts of devices (most notably digital video cameras) to your
|
|
computer.
|
|
|
|
If you have FireWire hardware and want to use it, say Y here. This
|
|
is the core support only, you will also need to select a driver for
|
|
your IEEE 1394 adapter.
|
|
|
|
To compile this driver as a module, say M here: the module will be
|
|
called ieee1394.
|
|
|
|
NOTE:
|
|
ieee1394 is superseded by the newer firewire-core driver. See
|
|
http://ieee1394.wiki.kernel.org/index.php/Juju_Migration for
|
|
further information on how to switch to the new FireWire drivers.

|
Enable this driver if you have an IEEE 1394 controller based on the
|
|
OHCI-1394 specification. The current driver is only tested with OHCI
|
|
chipsets made by Texas Instruments and NEC. Most third-party vendors
|
|
use one of these chipsets. It should work with any OHCI-1394
|
|
compliant card, however.
|
|
|
|
To compile this driver as a module, say M here: the module will be

called ohci1394.

NOTE:

ohci1394 is superseded by the newer firewire-ohci driver. See

|
further information on how to switch to the new FireWire drivers.
|
|
|
|
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 ohci1394
|
|
blacklist video1394
|
|
blacklist dv1394
|
|
or
|
|
blacklist firewire-ohci
|
|
|
|
to /etc/modprobe.conf or /etc/modprobe.d/* and update modprobe.conf
|
|
depending on your distribution.

This option enables you to use SBP-2 devices connected to an IEEE

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

This builds sbp2 for use with non-OHCI host adapters which do not

support physical DMA or for when ohci1394 is run with phys_dma=0.

Physical DMA is data movement without assistance of the drivers'

interrupt handlers. This option includes the interrupt handlers

|
that are required in absence of this hardware feature.

This option is buggy and currently broken on some architectures.

This driver implements a functional majority of RFC 2734: IPv4 over

1394. It will provide IP connectivity with implementations of RFC
|

2734 found on other operating systems. It will not communicate with
|
|
older versions of this driver found in stock kernels prior to 2.6.3.
|
|
This driver is still considered experimental. It does not yet support
|
|
MCAP, therefore multicast support is significantly limited.
