[linux-audio-dev] IRQ rotation

Hi all, This has been discussed briefly before: http://www.music.columbia.edu/pipermail/linux-audio-user/2003-March/002834.… It used to be possible (in the 2.0 kernel series) to the rotate priority of IRQs on the two controllers. This sounds really good as on my laptop the soundcard is welded to IRQ5 (very low priority) and everything else is on IRQ10 (higher, c.f. http://myweb.cableone.net/eviltwin69/Arcana.html sec 2.4), so I can only run the card with big buffers. The tool used to do the rotation was irqtune: http://cae.best.vwh.net/irqtune/ I'm downloaded it, hacked it to work with 2.4, but it doesnt seem to do anything (no errors, but no action either AFAICT). I'm wondering if somene here knows enough about the kernel to have a clue why its not doing anything. I can mail a patch to anyone whos interested, but as I said it doesnt work at the moment. I'm replacing this laptop soon, so its mostly academic interest, but it might have been of use to someone. Possibly something similar can be done with APIC, but it didn't seem to work very well on this machine last time I tried. - Steve
