INTRCTL(8)              NetBSD 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 com-
     mands 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 sepa-
                      rated 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.
