Hi, I used oprofile to trace for 60 seconds using the rtc option. My tick count is higher than I expected. What am I doing wrong?

It wasn't using RTC. oprofile will use the performance counters if they're there. We should error out if it's not in RTC mode, in fact, so this confusion doesn't happen again. regards john |
