You cannot expect people reacting immediately if something is wrong. There are and do exist enormous delays between publishing a new kernel and the decision to use it after appropriate system or distro update. So your expectation level is simply wrong. > Now, we have already a regression on a stable kernel, and solving it by > creating another regression is not something smart to do. Yes.

It's truly amazing how the filter system of your perception works, isn't it? :) It's not just "an old, orphaned application with a non-official patch on it." That's nonsense! a. As I stated already, there do exist several patched versions of alevt-dvb. For instance the one that Herman Pitton tested here in public causes a closed demux device error on my machine. That means that it does not run because xine-ui is already using the demux device. And this phenomenon has got nothing to do with the kernel headers! I've tried all possibilities (old kernel headers and actual ones) so I know better than Hermann Pitton does! And my version (and obviously the ones of Thomas Voegtle and Emil Meier whom I helped with my tip to revert that patch) cause a kernel crash with the actual kernel. b. As I also stated already the other teletext application called mtt does officially not exist except for Novell / OpenSuSe distros (at least as far as I have seen and found out). And this one is, as I also stated, not affected by the kernel patch. It's part of a discontinued program suite called xawtv-4.0 pre with a very complex infrastructure behind. Please do not ask me why this one runs without noise - I do not know. So AFAICS alevt-dvb is the ONLY teletext application for Linux which is available in almost all Gnu/Linux distros. "Other applications with similar features weren't affected." >From where do you know that the features are "similar"? This is a 100 % phantasy product of your mind that has got nothing to do with existing reality, man! Just one example: alevt-dvb has got an excellent html export filter which makes it possible to export teletext pages as graphical html files. I do not know any other teletext application offering that. > We are too late in -rc cycle, so probably there's not enough time for > writing, test, validate any new API in time for 2.6.33 and write some compat > layer to emulate those two ioctls with a different implementation. Who says that a new API or an overworked API must be ready for 2.6.33? When do you think the correct starting point must be set? When the merge window for 2.6.34 opens or when? Absurd argument! Not valid at all! > So, removing those two ioctls is not an option anymore. Yes. Conclusion??? None! So if everybody wants to close down this discussion with that output then you must admit (if you want it or not) that you de facto bury teletext usage in the mud for the majority of Gnu/Linux DVB users. So the output is more than badly disappointing. Bye bye Teletext. Nothing for future kernels, huh? Regards CS P. S.: If you continue like that you make people run away. Instead you better should try to win people, shouldn't you? Just see how many volunteers are here to help and then reflect why that manpower is missing, Mauro! Your gesture being expressed above does a lot, but it is definitely NOT motivating to change that precarious situation. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
