sendme [-a|-a PROC] [-b USEC] [-l loops] [-p PRIO]
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.
- -a, --affinity[=PROC]
- Run on processor 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.
