irqtop - utility to display kernel interrupt information

-C, –cpu-list list

Specify cpus in list format to show.

-d, –delay seconds

Update interrupt output every seconds intervals.

-s, –sort column

Specify sort criteria by column name. See –help output to get column names. The sort criteria may be changes in interactive mode.
