What is Irqbalance
Irqbalance is a daemon to help balance the cpu load generated by interrupts across all of a systems cpus. Irqbalance identifies the highest volume interrupt sources, and isolates each of them to a single unique cpu, so that load is spread as much as possible over an entire processor set, while minimizing cache miss rates for irq handlers.
Building and Installing
./autogen.sh
./configure [options]
make
make install
Developing Irqbalance
Irqbalance is currently hosted on github, and so developers are welcome to use the issue/pull request/etc infrastructure found there.

/proc/interrupts
outputirqbalance --debug
output- content of smp_affinity files - can be obtained by e.g.:
$ for i in $(seq 0 300); do grep . /proc/irq/$i/smp_affinity /dev/null 2>/dev/null; done
- your hw hierarchy - e.g.
