tools/power turbostat: simplify output, add Avg_MHz
Use 8 columns for each number ouput. We don't fit into 80 columns on most machines, so keep the format simple. Print frequency in MHz instead of GHz. We've got 8 columns now, so use them to show low frequency in a more natural unit. Many users didn't understand what %c0 meant, so re-name it to be %Busy. Add Avg_MHz column, which is the frequency that many users expect to see -- the total number of cycles executed over the measurement interval. People found the previous GHz to be confusing, since it was the speed only over the non-idle interval. That measurement has been re-named Bzy_MHz. Suggested-by: Dirk J. Brandewie Signed-off-by: Len Brown <len.brown@intel.com>
