Hi All,
One of the few reasons why Fedora is my distro of choice is because its usually
cutting edge, and I like to be where the development is happening.
However today I've had an encounter with Fedora which make me wonder if
sometimes we aren't a little too cutting edge. I tried to get an industrial
firewire camera to work with the stock Fedora kernel using the juju stack. Long
story short, it didn't work.
Which after reading: http://wiki.linux1394.org/JujuMigration Isn't really
surprising, quoting that page: "Almost no support for IIDC cameras: Not
compatible with libdc1394 v1. Highly experimental support in libdc1394 v2 which
works with some luck on only a few OHCI 1.1 controllers. Improvements are to be
expected in Linux 2.6.25-rc1."
Notice how a preliminary fix is expected for 2.6.25, which probably means that
this will still be broken in Fedora 9, notice that the breakage was introduced
in Fedora 7, so thats 18 months worth of broken firewire camera support (iow
most digital video cameras). Add to that that the above referenced wiki page
also says: "Regarding Linux 2.6.22 and 2.6.23, the best advice to Linux
distributors (kernel packagers) ... is: Build only the old IEEE 1394 drivers."
libdc1394 isn't part of Fedora, so that's outside the scope of this
discussion.
Well actually it has been in review for quite a while, with the juju stack
being one of the reasons for it not passing review yet (patents is another, but
a patent free version is most likely possible).
I would like to work on getting this into Fedora, and if things could be fixed
so as to work with the new stack, I'm all for it. Shipping something which
still doesn't work in F-9 makes us look rather bad IMHO, doing new things can
cause breakage, but breakage for 3 releases in a row?
As for the necessary Juju bits, they're already in Fedora 7 and Fedora
8. See this bug: https://bugzilla.redhat.com/show_bug.cgi?id=344851
That fix is included in kernel 2.6.23.9-44.fc7, 2.6.23.9-78.fc8, and
rawhide. It'll hit the *upstream* kernel in 2.6.25.
As for this being fixed, not for my case, as I have a via vt 6306 controller,
which is like, only the most common PC firewire controller on the planet.
Note that I'm more then willing to help debug this, I've added myself to the CC
of: https://bugzilla.redhat.com/show_bug.cgi?id=415841
Anything I van do to help?
Regards,
Hans
