  • Troubleshooting VTune(TM) Amplifier XE's Power Analysis

    We have recently learned about various problems users are experiencing when attempting to use the power analysis capability of the VTune™ Amplifier XE 2013.  For example, you may see one of the following messages:

    • Error: Power Analysis is not supported on this platform.
    • Unknown symbol "cpufreq_freq_attr_scaling_available_freqs" in /var/log after building and attempting to load the power driver module

    Below are some suggestions for troubleshooting problems with the power analysis feature.

    There are 8 MEM_TRANS_RETIRED.LOAD_LATENCY_GT_* precise events available on Intel® Microarchitecture Codename Sandy Bridge.  The events allow you to pinpoint loads that exceeded a given latency, measured in CPU clock cycles.  For example, the MEM_TRANS_RETIRED.LOAD_LATENCY_GT_4 event is for loads exceeding 4 clocks in latency, and the MEM_TRANS_RETIRED.LOAD_LATENCY_GT_512 event is for loads longer than 512 clocks.
