[linux-audio-user] kernel - using rtlimits, realtime_lsm

Hello all, I'm a bit over my head here, so please be gentle :) I've been working with Ubuntu 5.10 and trying to use it as an audio machine. I have been learning about different approaches to getting a multimedia kernel (low latency, etc.). In reading around the web, I see that there are three general approaches: 1. Build your own kernel from scratch - too complicated for me at this time 2. Use the realtime_lsm module on an existing kernel - I've tried this, but I read it's no longer supported in the kernel because of #3... 3. Use rtlimits, which is already a part of the default kernel. Last night I downloaded the set_rtlimits program and was able to get jackd running with real time capabilities. I haven't done any real-world work yet, so I don't know if my efforts were truly successful. Here are my questions: 1. Is rtlimits all that I need for audio work? It seems way too simple. I remember that people using 2.4 kernels had at least two patches that had to be applied before the kernel was suitable for audio work. If I use rtlimits, do I still need to build a kernel with, for instance, the ck patches for a preemptable kernel? 2. Is anyone using rtlimits instead of realtime_lsm? Is there any benefit to using one over the other, in terms of real-world audio work? 3. Should I just break down and install DeMudi? :) I hope my questions make sense. Please feel free to correct any errors in my logic here, that is exactly what I am looking for - to learn how to do things myself the right way. Thanks! Josh -- Josh Lawrence http://www.hardbop200.com
