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.
