sendme(8) sendme(8)NAMEsendme - Send a signal from driver to user and measure time intervalsSYNTAXsendme [-a|-a PROC] [-b USEC] [-l loops] [-p PRIO]DESCRIPTIONThe 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.FILESbackfire.koEXAMPLES# modprobe backfire # sendme -a -p99 -l1000000 Samples: 1000000 To: Min 0, Cur 0, Avg 1, Max 11 From: Min 2, Cur 3, Avg 3, Max 43AUTHORSCarsten Emde <C.Emde@osadl.org>SEE ALSObackfire(4) 0.2 sendme(8)
