Cannot run Power Analysis using VTune 2013!

[kang_z_Intel]

I installed VTune Amplifier 2013, and wish to run the power analysis.

After building project and new analysis, the item of power analysis showed the following error:

$isPowerAnalysisAvailable == PlatformError: cannot compare boolean values with arguments other then 'true' or 'false'

And the buttom of "Start" cannot be used...

Could you tell me how to deal with it? Thanks!!

btw, the drivers for power analysis have been built again following the steps of /opt/intel/vtune_amplifier_xe/powerdk/src/README.txt.

Ensure that you work on latest Update 5, and Linux* kernel version should be greater than 2.6.32

Assume that you already built/installed power driver, use "lsmod | grep apwr" to check.

Then, use

# amplxe-cl -collect frequency -- program

# amplxe-cl -report frequency-analysis ./r00?frequency

Or you can use amplxe-gui to open result.

Thanks! I checked my kernel version at /proc/version, it is Linux version 3.2.0-29-generic. Although it is higher than 2.6.32, I think it may be OK.

And, I checked the items shown in http://software.intel.com/en-us/articles/troubleshooting-vtunetm-amplifier-xes-power-analysis

there is only one problem: when running 'lsmod | grep cpufreq', there is nothing shown....

but other items are all OK, for example, CONFIG_X86_ACPI_CPUFREQ=y.

And then, I tried to run a power analysis, but VTune stilll cannot work,

It shows "Collection failed. Cannot start collection of power events" ERROR. :(

Maybe Linux kernel 3.2 is too higher to support cpufreq driver, try kernel v3.1?
