| .SH "DESCRIPTION" | |
| .LP | |
| The program \fBsendme\fR uses the \fBbackfire\fR 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. | |
| .SH "OPTIONS" | |
| .TP | |
| .B \-a, \-\-affinity[=PROC] | |
| Run on processor number PROC. If PROC is not specified, run on current processor. | |
| .TP | |
| .B \-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. | |
| .TP | |
| .B \-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. | |
| .TP | |
| .B \-p, \-\-prio=PRIO | |
| Set the priority of the process. | |
