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.
