How to get call stack of L2 cache misses?

Hello all

It seems to me that VTune only measures L2 cache misses in a hardware sampling analyses, whereas the call stack is only obtained by user mode analysis.

Is there any way to put the two together and obtain the call stack for my L2 cache misses?

Many thanks,

C.

The quick answer is:
VTune Amplifier XE supports Statistical Call Graph feature for user-mode sampling data collection only, all hardware event-based sampling data collection does not support this feature, including lightweight-hotspots data collection, memory access analysis, etc.

I understand that it could be a new feature request to the product.

Regards, Peter
