[PCM] pcm-power.x tool does not report the frequency bins.

hilgeman commented on the Intel PCM article:

The pcm-power.x tool does not report the frequency bins. No matter what bins I use with the -p 0 option and -a/-b/-c frequency values, the percentages always remain zero:

Martin,

I could reproduce this on an Intel Xeon E5 v3 processor, and we are looking into right now.

Kind regards
