cyclictest(1) Xenomai high resolution timer test


cyclictest [options]


cyclictest is part of the Xenomai test suite and tests the POSIX skin of Xenomai with a cyclic timer test.

For this program to work, you need to run a suitable Xenomai enabled kernel with the respective module (xeno_posix).


cyclictest accepts the following options:

-b USEC, --breaktrace=USEC

send break trace command when latency > USEC

-c CLOCK, --clock=CLOCK

select clock: 0 = CLOCK_MONOTONIC (default) 1 = CLOCK_REALTIME

-d DIST, --distance=DIST

distance of thread intervals in us default=500

-i INTV, --interval=INTV

base interval of thread in us default=1000

-l LOOPS, --loops=LOOPS

number of loops: default=0 (endless)

-n, --nanosleep

use clock_nanosleep

-p PRIO, --prio=PRIO

priority of highest prio thread

-q, --quiet

print only a summary on exit

-r, --relative

use relative timer instead of absolute

-t NUM, --threads=NUM

number of threads: default=1

-v, --verbose

output values on stdout for statistics

format: n:c:v n=tasknum c=count v=value in us
