NAME

       sendme - Send a signal from driver to user and measure time intervals

SYNTAX

       sendme [-a|-a PROC] [-b USEC] [-l loops] [-p PRIO]

DESCRIPTION

       The  program  sendme  uses the backfire driver to send a signal from driver to user. It then reads the timestamp from the driver and calcu-
       lates the time intervals to call the driver and to receive the signal from the driver.

OPTIONS

       -a, --affinity[=PROC]
	      Run on procesor number PROC. If PROC is not specified, run on current processor.

       -b, --breaktrace=USEC
	      Send break trace command when latency > USEC. This is a debugging option to control the latency tracer in  the  realtime	preemption
	      patch.  It is useful to track down unexpected large latencies on a system.

       -l, --loops=LOOPS
	      Set  the	number of loops. The default is 0 (endless). This option is useful for automated tests with a given number of test cycles.
	      Sendme is stopped once the number of timer intervals has been reached.

       -p, --prio=PRIO
	      Set the priority of the process.

NAME

       cyclictest - Xenomai high resolution timer test

SYNOPSIS

       cyclictest [options]

DESCRIPTION

       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).

OPTIONS

       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
