I also tried with the irqbalance daemon, on ARM quad core architecture, and as per my understanding, the daemon sets the /proc/irq/<irq.no.>/smp_affinity file according to the irq frequency on a particular processor.
However, the daemon doesn't work as expected, I also tried accessing the proc file mentioned above to set the cpu mask for particular irq, but this just block the processing of the irq, as I see the count of that irq doesnt increase in /proc/interrupts.
My conclusion is that the irqbalancing is not supported on ARM arch or there is something more required for this to work. Kindly provide some pointers over this.
Regards, Vaibhav
