Hi,
I am running 2.6.0-test2-mm4 on an SMP machine with dual Athlon MP
2000+s.
/proc/stat displays:

I am not sure why the intr line contains all those zeros. Is this
normal behavior?
Thanks,

Yes, for most architectures, it prints interrupts from 0 thru NR_IRQS:
for (i = 0 ; i < NR_IRQS ; i++)
len += sprintf(page + len, " %u", kstat_irqs(i));
and NR_IRQS varies depending on the kernel build options, but (for x86)
is usually either 16 or 224.

Eww. So I guess on SMP, it is 224.
Might be nice to only print lines that are registered, like
/proc/interrupts. But then you have no way of knowing which field is
which interrupt line. Ugh.
How can we expect anything to parse that line?

Ugh-ly? We can move it to sysfs and then change the file format
to intnum:count pairs (e.g.).

But then how is it different from /proc/interrupts ?

On i386 you can find out the last irq line number during MP table parsing
(ACPI bits are also in mpparse.c), for the hotplug case i suppose the
hotplug code could bump this up as devices get attached. But unless we do
dynamic NR_IRQs its all just too much effort.
