It has become clear that out-of-tree drivers often do not get any better until they are merged; meanwhile, users want those drivers and distributors are shipping them. Here we have again one guy against a supposed “clique” of kernel developers. The sad story of the em28xx driver Posted Nov 12, 9: His efforts to enhance that driver quickly ran into trouble, though, when he tried to make substantial changes to the low-level tuner interface – changes which affected a number of other drivers. There seems to be little doubt that it has developed well beyond the in-tree driver; it supports a wider range of devices.

After few years he started to close bugs and feature requests with “use reiser4” effectively abandoning users and stopped reiserfs support when something went wring he pointed out that the same thing worked perfectly with previous version of kernel and basically refused to debug and em288xx problems thus abandoning developers.

Also quite a few bugs have been fixed in the kernelframework eg tuner-core it cost alot time all together and the ek28xx didn’t get valued at all. These changes were not popular in the Video4Linux community, and there were fears that they could break unrelated drivers. The sad story of the em28xx driver Posted Nov 24, I wanted to do it.

Failure to merge it risks losing the work that has been done, and, perhaps, losing em28cx future work of a developer who, for all his faults, is clearly trying to provide a better experience for Video4Linux users.

By Jonathan Corbet November 11, In the process, this long story has helped to give the Video4Linux development community a bit of a reputation as a dysfunctional family – a perception which those developers are only now beginning to overcome.

The sad story of the em28xx driver Posted Me28xx 17, It could easily be that this was mistaken though. And in most cases newer drivers support more hardware, not less.

On the other hand, video developer Hans Verkuil reviewed the new driver and concluded: They fight for at least three years now and they still don’t have a useful infrastructure to support DVB-S2 devices. Reality is probably a bit more complex though. Markus Rechberger The empja story of the em28xx driver.

Mauro doesn’t explain his reason for not wanting both. I got around i2c-dev which allows the access of those shared components in userland, the only outstanding gap in order to remain compatible with existing tv apps was to add a small wrapper to resubmit the controls to userspace sick isn’t it? Posted Nov 15, 5: Maybe Jon’s article can be the crystallization point for everybody to take a step back and go on a path of compromise instead of confrontation hope springs eternal, I know In the referenced posting, you suggest that time could be used better to fix e,28xx.

Ok I acknowledge that is what’s wanted and how it should be done. The userspace drivers used a couple of self written drivers. It’s might be quite a problem for Linux as a platform when developers with such access to the hardware specs as Markus can’t even properly contribute to the mainline kernel driver.


There are users who will attest that the drivers work, and that Markus provides good support for them. He then continued development of the code, hosting it on his own server.

That seems to be the opposite of the open source process. Multiple drivers are easily accepted as temporary solution, but then someone must merge support for other hardware – and then we have “reiserfs situation” where developer works for it’s own feature and against all others Posted Nov 26, It can do some setup steps which the API currently cannot handle. Best would be to replace you as a maintainer since you don’t have any respect of others work either.

Now one group the v4l group has taken over without taking other dvb people who managed the project before as a small group before So this code was not merged. Em28xxx I once asked him about joining that stuff he just told me well but you have it already done.

The sad story of the em28xx driver Posted Nov 20, So it would seem that everybody’s interests are served by getting those drivers into the mainline tree.
