Above you need to explain. Your overall settings - to me at least - are still looking like you're playing parameter bingo, without understanding much of it. Above parameters define the realtime schedulers time frame, which can be allocated by realtime capable processes. The first parameter says from 1s overall 0.9999999s can be allocated by SCHED_RT processes. The remainder towards 1s = 0,0000001s ( maybe I missed a digit) can be allocated by SCHED_OTHER (all processes without rt-scheduling). If you comment above values out you fall back to default values: 10000000 9500000 which means 0.05s can be used by SCHED_OTHER. In your setup you put quite a lot of processes on IRQs on SCHED_OTHER. If you comment out above commands you'll cause less stress to the SCHED_OTHER group. You achieve exactly the opposite you're claiming. With this you'll concentrate on all other than audio processes. They key challenge on an rt system is to find the right balance between all the processes running. And that's a pretty complex task. And there's more than one solution. I doubt that "industry experts" supported you on this (and on many more of your settings). The overall approach of reducing load on the system with special focus on the audio process has not been your invention btw!!! It's known for quite some time. Anyhow. Keep going. But do your self a favour. Better stop making claims about this or that. You're still PiggyBacking on things other people have figured out.
