Hi,

Is there any reason to put this complexity in the kernel instead of
doing it from a userspace daemon?

A userspace daemon can do higher level evaluations, read config files
about the system (like numa configuration etc etc) and all 2.4/2.5
kernels already have a userspace api for setting irq affinity..

an example of a simple version of such daemon is:
http://people.redhat.com/arjanv/irqbalance/irqbalance-0.03.tar.gz

any chance of testing this in an intel lab?

Greetings,
