x00456305 0c097c000e use policy prior to the default values Currently user-defined policies against non-PCI devices' interrupts are not working properly. For example, when trying to set "balance_level=core" for a non-PCI device interrupt which is classified as "other", will result in the level of "package" because overrided in add_new_irq(). This patch fixes this by restricting irq info initializations in add_one_irq_to_db(), which requires a change on its parameters.

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

./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
