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 calculates 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.
