likwid - issue #98

Events reported with "-H -g" switches not correct for L3CACHE group on AMD Interlagos

Posted on Mar 7, 2013 by Swift Wombat

What steps will reproduce the problem? 1. On AMD Interlagos 6272 2. Execute "likwid-perfctr -H -g L3CACHE" 3. See "formulas" reported.

What is the expected output? What do you see instead? Expected output of the formulas should mention L3 cache events or relevant metrics. Tool reports "L2" events mistakenly.

What version of the product are you using? likwid-3.0-BSD

Please provide any additional information below. When actually using the event group, events measured are correct and relevant to the L3 cache. This is simply an "interface" mishap.
