Get L3 cache misses on xeon X7460

Hello,

What event(s) I have to collect in order to get L3 cache misses on xeon X7460 ?
I don't find any L3 related events on the vtune events list.

On the intel manual, I have find "LLC cache misses" with
Event Num : 2EH and Umask Value : 41H

I have tried to edit an event in order to put this values, but I can't get any events...

What is wrongs ?

Thanks

Regards

Matthieu

Hello Matthieu,

Performance monitoring of L3 cache unit in the Intel Xeon processor 7400 series is not supported by VTune Performance Analyzer.

Please refer to the manual which talks about performance monitoring on L3 cache: http://www.intel.com/Assets/PDF/manual/253669.pdf

Thanks
