Hello, I'm doing some experiments with oprofile on a Intel Xeon E7330 (Core 2). I want to track programmable and fixed counters at the same time, but I can add no more than 2 events in oprofile. I have no idea on how to track the fixed counters. Anyone can help? Thanks --matteo |

I want to track programmable and fixed counters at the same time, but I can add no more than 2 events in oprofile. I have no idea on how to track the fixed counters. Anyone can help? There's currently no support for fixed counters in oprofile. I had an experimental patch once, but it ran into a couple of problems, so it was not really usable. The only way to use them is to use a different profiler or program/read them directly using /dev/cpu/*/msr -Andi -- ak...@li... |
