    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.
