# NAME

`intrctl` —
program to control interrupts

# SYNOPSIS

`intrctl` | command [options]

# DESCRIPTION

The `intrctl` command can be used to control and inspect the state of interrupts in the system.

The first argument, command, specifies the action to take. Valid commands are:

affinity `-c` cpu_index `-i` intrid
  set an intrid interrupt's affinity to cpu_index.
intr `-c` cpu_index
  enable to set an interrupt's affinity to cpu_index. If cpu_index is already enabled, this command has no effect.
list [`-cz`] [`-w` wait]
  for each intrid in the system, display interrupt counts per CPU. The intrid is an interrupt name such as "ioapic0 pin 22" for x86.

  If `-c` is specified, display compact list with total counts per interrupt, and CPU affinity as list of CPU indexes.

  If `-w` is specified then `intrctl` display the data continuously with a wait seconds delay between each iteration.

  If `-z` is specified then rows with all CPUs having zero interrupts will be skipped.

nointr `-c` cpu_index
  disable to set an interrupt's affinity to cpu_index. If cpu_index is already disabled, this command has no effect.
