So adding isolcpus=7 to your kernel parameters and
running jack (and
maybe zita bridge) with tasksel -c 7? And maybe even bind that soundcard
IRQ to that CPU as well?
Since jack does not support smp anyway, there is nothing to lose, but
some given away CPU cycles, as that CPU will be bored and not be
available for other tasks.
Jack2 does support SMP so I wouldn't pin that to one CPU. If you use
Jack1 it might be an option but I wonder how much you would gain with
that. I really think it would be better to not try meddling with
scheduling IRQ requests yourself and have the system handle it. Just my
2¢ ;)
