Re: [LAU] pretty much frustrated about those rt-kernels!

Hi, Since over three years jacklab try to find out what is the best supported rt-kernel on opensuse. The early self compiled 2.6.x rt-kernels broke a lot of drivers and it was not easy for users to extend them with kernel modules or drivers (for nvidia etc) and often the audio priority was a showstopper (xruns!). We decided to rebuild an own rt-kernel (incl all suse patches) for JAD 1.0. (based on oS 10.2). Since 10.3 opensuse offers a kernel-rt, but without the corresponding kernel modules nor kernel-rt-source for build up a proprietary nividia driver (needed for dualhead support) and not at least the "rtc tick is to low" for Rosegarden. The opensuse rt-kernel is not for musicians, it is for SLERT, an enterprise realtime linux. (btw: One of the former LAC founder and synthgeek Matthias Nargoni is the Novell Manager for SLERT) The rt-kernel for oS 11 also doesn't supported well by Suse, still no sources. But the experienced Suser (free suse package builder) Jan Engelhard (jengelh) now offers in his repository a good (mature and fast) rt kernel with nivida-gfx and some kernel modules. He have an open ear for the needs of musicians. With the 2.6.25.8 (patched with rt6) opensuse 11 has a better audio realtime then ever. I can use half of the buffers that I needed with the rt-kernels from the past. The rt audio performance is comparable to 64studio (my personal reference audio linux). Packman offers most of the pro audio software we need, since jacklab and packman joined forces by merging their repositories, and if there is something missing (like wineasio or dssi-vst), you will find it in the jacklab repo or in the 100 other repos around the opensuse build server. http://forum.jacklab.net/viewtopic.php?f=25&t=794 The situation on opensuse Linux is pretty good for musicians at this time :) The next time the jacklab devel Olli Bengs (Applelonkel) has planed to release an installable live dvd named JAD 2.0, a remastered oS 11 for musicians. The jacklab community is very enthusiastic about this release, because it looks very good, also the 64-bit version (oS 11 x86_64) works well on my test system. have a nice day!
