      turbostat is a Linux tool to observe proper operation
      of Intel(R) Turbo Boost Technology.
      
      turbostat displays the actual processor frequency
      on x86 processors that include APERF and MPERF MSRs.
      
      Note that turbostat is of limited utility on Linux
      kernels 2.6.29 and older, as acpi_cpufreq cleared
      APERF/MPERF up through that release.
      
      On Intel Core i3/i5/i7 (Nehalem) and newer processors,
      turbostat also displays residency in idle power saving states,
      which are necessary for diagnosing any cpuidle issues
      that may have an effect on turbo-mode.
      
      See the turbostat.8 man page for example usage.
