This is the "Juju" FireWire stack, a new alternative implementation
|
||||
designed for robustness and simplicity. You can build either this
|
||||
stack, or the old stack (the ieee1394 driver, ohci1394 etc.) or both.
|
||||
Please read http://ieee1394.wiki.kernel.org/index.php/Juju_Migration
|
||||
before you enable the new stack.
|
||||
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.
|
||||
|
||||
This module functionally replaces ieee1394, raw1394, and video1394.
|
||||
To access it from application programs, you generally need at least
|
||||
libraw1394 version 2. IIDC/DCAM applications also need libdc1394
|
||||
version 2. No libraries are required to access storage devices
|
||||
through the firewire-sbp2 driver.
|
||||
libraw1394 v2. IIDC/DCAM applications need libdc1394 v2.
|
||||
No libraries are required to access storage devices through the
|

|
||||
|

NOTE:

ohci1394, raw1394).
