4. the merging process stalled considerably when the paken fork was
discovered
The root of the problem of course is ivtv developpers still haven't
understood the "release early, release often" part and are aiming for
a perfect (cleaned-up and feature-complete) driver before submitting
it. Instead of merging everything now (experimental) and finishing the
paken merge cleanup / inside the kernel.
ivtv 0.5 is not even available as a kernel patchset, so you get the
idea. ivtv writers would get a boatload of feedback if it behaved like
any other kernel patchset.
Now don't get me wrong, the ivtv people did and are doing a wonderful
job driver-side, but they seriously need to learn to integrate in the
kernel ecosystem. Someone wrote in the thread about the need to "kick"
them a bit to make them understand this. I'm afraid this feeling is
shared by a lot of other people. The low priority given to merging is
real frustrating.
Please, give them a break, and let's end this conversation right now.
IVTV has come a long way in a path of merging into V4L, especially
during 2.6.15 development. This is not simply a matter of getting the
ivtv code into the kernel to let it compile correctly.... This is also
an issue of changing the ivtv modules to conform with the V4L2 API, and
to make all of these modules behave in the same style as the other v4l
kernel modules, so that other devices can use the ivtv modules, etc.
We are trying to encourage proper codingstyle, so that things are
correct from the start... This is not simply a matter of merging in a
new module -- When ready, the ivtv modules will become part of the v4l
subsystem, and card drivers will make use of them. These modules must
conform to a standard API as the rest of V4L does... Otherwise, we would
be creating more work for ourselves later on.
I can go on and on explaining why there needs to be work done before
this is all merged in... but simply enough, it isn't ready. (although
it seems to be getting there soon) There are people working on it, and
significant headway has been made in the past few months. We want this
to be done correctly -- not quickly for a deadline. Remember, the
people working on this code are doing it because they want it to work --
NOT because they have a deadline in order to receive a paycheck. Please
have some patience, and things will be better in the longrun.
About the dependency on the v4l cvs tree, this is part of the transition
-- When the ivtv guys are finished with a module, it goes to the v4l-dvb
cvs, where we will make additional cleanups, and set up Kconfig, etc...
Now that there is this "upstream merge window" policy, that explains why
there are some ivtv dependencies in v4l-dvb cvs, that are not yet in the
kernel. If you read the ivtv mailing list, or the web site
instructions, you will understand that there is a 0.4.x series, for use
as standalone, and a 0.5.x series, which depends ont the v4l-dvb tree.
I'm done rambling.... Just have patience.... Merges will happen soon
enough. Please dont try to rush things.
Cheers,
Michael Krufky
P.S.: Hans, Taylor, and all the other ivtv developers - You're doing a
great job, and keep up the good work. This just goes to show how much
the community appreciates the work of the ivtv project. :-D
