   9 == NAME
  10
  11 irqtop - utility to display kernel interrupt information
  12
  13 == SYNOPSIS
  14
  15 *irqtop* [options]
  16
  17 == DESCRIPTION
  18
  19 Display kernel interrupt counter information in *top*(1) style view.
  20
  21 The default output is subject to change. So whenever possible, you should avoid using default outputs in your scripts. Always explicitly define expected columns by using *--output*.
  22
  23 == OPTIONS
  24
  25 *-o*, *--output* _list_::
  26 Specify which output columns to print. Use *--help* to get a list of all supported columns. The default list of columns may be extended if list is specified in the format _+list_.
  27
  28 *-c*, *--cpu-stat* _mode_::
  29 Show per-cpu statistics by specified mode. Available modes are: *auto*, *enable*, *disable*. The default option *auto* detects the width of window, then shows the per-cpu statistics if the width of window is large enough to show a full line of statistics.
  30
  31 *-C*, *--cpu-list* _list_::
  32 Specify cpus in list format to show.
  33
  34 *-d*, *--delay* _seconds_::
  35 Update interrupt output every _seconds_ intervals.
  36
  37 *-s*, *--sort* _column_::
  38 Specify sort criteria by column name. See *--help* output to get column names. The sort criteria may be changes in interactive mode.
  39
  40 *-S*, *--softirq*::
  41 Show softirqs information.
