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.
