I have patches to fix this.
But, I the problem is that both soft interrupts and vector interrupts
are useful to know. All vector interrupts are dispatched via soft
interrupts, so if we count both, the interrupt count is double. We
need soft interrupts if we want to see the clock ticking.
bash-2.05b$ vmstat -i
interrupt total rate
stray 1 0
pil 1 0
ithrd pil2 69163 16
gem0 vec2012 27748 6
gem1 vec1990 70 0
atapci0 vec1996 41345 9
tick pil14 421278 99
Total 559606 132
notice that ithrd is equal to gem0 + gem1 + atapci0. pil is the
priority interrupt level (aka soft interrupts).
Comments? Do we count both? or not include soft interrupts? or not
include the ithrd pil?
