LATENCY(1) Xenomai LATENCY(1)NAME
latency - Xenomai timer latency benchmark
SYNOPSIS
latency [options]
DESCRIPTION
latency is part of the Xenomai test suite. It is a timer latency benchmark program. The system must run a suitable Xenomai enabled kernel
with the respective module (xeno_timerbench).
OPTIONS
latency accepts the following options:
-h print histograms of min, avg, max latencies
-s print statistics of min, avg, max latencies
-H <histogram-size>
default = 200, increase if your last bucket is full
-B <bucket-size>
default = 1000ns, decrease for more resolution
-p <period_us>
sampling period
-l <data-lines per header>
default=21, 0 to supress headers
-T <test_duration_seconds>
default=0, so ^C to end
-q supresses RTD, RTH lines if -T is used
-D <testing_device_no>
number of testing device, default=0
-t <test_mode>
0=user task (default), 1=kernel task, 2=timer IRQ
-f freeze trace for each new max latency
-c <cpu>
pin measuring task down to given CPU
-P <priority>
task priority (test mode 0 and 1 only)

rtcanrecv - Xenomai tool for receiving CAN messages
SYNOPSIS
rtcanrecv [<can-interface>] [Options]
DESCRIPTION
rtcanrecv is part of Xenomai. It is used to receive messages via a CAN interface. The system must run a suitable Xenomai enabled kernel
with the respective module (xeno_native and the CAN driver).
OPTIONS
<can-interface> is the CAN interface file.
rtcanrecv accepts the following options:
-f, --filter=id:mask[:id:mask]...
apply filter
-e, --error=mask
receive error messages
-t, --timeout=MS
timeout in ms
-T, --timestamp
with absolute timestamp
-R, --timestamp-rel
with relative timestamp
-v, --verbose
be verbose
-p, --print=MODULO
print every MODULO message
-h, --help
