|
.Ar command
|
|
.Op Ar options
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command can be used to control and inspect the state of interrupts
|
|
in the system.
|
|
.Pp
|
|
The first argument,
|
|
.Ar command ,
|
|
specifies the action to take.
|
|
Valid commands are:
|
|
.Bl -tag -width XofflineXcpunoX
|
|
.It affinity Fl c Ar cpu_index Fl i Ar intrid
|
|
set an
|
|
.Ar intrid
|
|
interrupt's affinity to
|
|
.Ar cpu_index .
|
|
.It intr Fl c Ar cpu_index
|
|
enable to set an interrupt's affinity to
|
|
.Ar cpu_index .
|
|
If
|
|
.Ar cpu_index
|
|
is already enabled, this command has no effect.
|
|
.It list Oo Fl cz Oc Oo Fl w Ar wait Oc
|
|
for each intrid in the system, display interrupt counts per CPU.
|
|
The intrid is an interrupt name such as "ioapic0 pin 22" for x86.
|
|
.Pp
|
|
If
|
|
.Fl c
|
|
is specified, display compact list with total counts per interrupt,
|
|
and CPU affinity as comma separated list of CPU indexes.
|
|
.Pp
|
|
If
|
|
.Fl w
|
|
is specified then
|
|
.Nm
|
|
display the data continuously with a

.Ar wait
|
|
seconds delay between each iteration.
|
|
.Pp
|
|
If
|
|
.Fl z
|
|
is specified then rows with all CPUs having zero interrupts will be skipped.
|
|
.It nointr Fl c Ar cpu_index
|
|
disable to set an interrupt's affinity to
|
|
.Ar cpu_index .
|
|
If
|
|
.Ar cpu_index
|
|
is already disabled, this command has no effect.
