Hi folks,
I am reading this blog: http://www.ntop.org/pf_ring/irq-balancing/, and got
really confused by the irq balancing.
In this blog, it said:
~# grep eth /proc/interrupts
191: 0 0 3 0 0 0 2 310630615 454 0 0 0 0 0 2 0 PCI-MSI-edge eth5-rx-3
so, it looks like only one cpu handling interrupt 191, but, meanwhile, the
smp_affinity is like this:
# cat /proc/irq/19[12345]/smp_affinity
00008080
my question is, is this "00008080" means there will be two cpus(cpu0 and
cpu8) to handle irq 191? why this configure not take effect?
Thanks.
Alan
