Hi Jan,
it is the first time I use oprofile, I hope I have here results that are
significant...
I wrote a bash script to start everything:
--------------------
#!/bin/bash
opcontrol --start
./performance
opcontrol --stop
opreport
--------------------
My real time test application is called "performance".
Here is the output:
------------------------------------------------------------
Profiler running.
delta is 2023521331 per step: 5058
Stopping profiling.
CPU: P4 / Xeon, speed 3192.18 MHz (estimated)
Counted GLOBAL_POWER_EVENTS events (time during which processor is not stopped)
with a unit mask of 0x01 (mandatory) count 100000
