INTRCTL(8)

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 [-c]
    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 comma separated list of CPU indexes.

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.
