Neil Horman 10bb3d63d4 misc: add sample udev rule 
Its possible for irqbalance to miss device adds/removes during its sleep
time. These udev rules can help fix that.

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 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 Build Status

./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. However, most development discussions take place on the irqbalance mailing list, which can be subscribed to at: http://lists.infradead.org/mailman/listinfo/irqbalance

New Developers are encouraged to use this mailing list to discuss ideas and propose patches.

Bug reporting

When something goes wrong, feel free to send us bugreport by one of the ways described above. Your report should include:

  • Irqbalance version you've been using (or commit hash)
  • /proc/interrupts output
  • irqbalance --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. lstopo-no-graphics output
