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.
