I guess you're right, I could change the name.
I liked the name itop, it sounds good, and it's the perfect name for
this soft. That's why people already used it before.
But I think I'll rename it to 'inttop', it's pretty much the same, and
it tell what it does.

You might want to change the name, there are already 2 itops that I
know of, that monitor interrupts:

Yours provides much more information (works fine on my machine BTW),
so it's a useful addition, but if you just call it itop it's going to
be a bit confusing..

lately I had to fight big XRUN troubles, and thanks to this forum
I finally solved that. This excellent thread saved me:
On my long quest, I tried to see a little bit more what happened
with the IRQs on my system. I searched for a kind of 'top' utility
to monitor the interrupts, but the only apps I found were either
deprecated, or missed some cool features.
So, I ended up writing my own tool to monitor the file
It's available a this address:
As its name indicates, it behaves pretty much like top, but for
It's quite a simple thing, that I tried to enhance a bit with some
+ refresh period can be specified.
+ two display modes: display interrupts for every CPU, or only a
sum of all CPU.
+ display every interrupt (sorted like /proc/interrupts), or only
active interrupts (sorted by activity).
+ in case the number of interrupts changes during the execution
of itop (due to a rmmod/modprobe), it's handled without any fuss.
+ command-line options are also available as hotkeys for convenience.
+ at last, the program display a summary on exit. The idea is
that this summary could be copied/pasted in emails to help debugging.
