INTRCTL(8) FreeBSD System Manager's Manual 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 [-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.
