It might not be possible :) Not that I know for sure, but I'd imagine that the best you can do on older cpus is to use the performance governor.

You probably ought to give the interrupt handler servicing the FW interface the highest priority, and then follow the same instructions I gave in a previous post for setting up realtime priorities. -- Joakim _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
