    tools/power turbostat: print more turbo-limit information · 6574a5d5

    The "turbo-limit" is the maximum opportunistic processor
    speed, assuming no electrical or thermal constraints.
    For a given processor, the turbo-limit varies, depending
    on the number of active cores.  Generally, there is more
    opportunity when fewer cores are active.
    Under the "-v" verbose option, turbostat would
    print the turbo-limits for the four cases
    of 1 to 4 cores active.
    Expand that capability to cover the cases of turbo
    opportunities with up to 16 cores active.
    Note that not all hardware platforms supply this information,
    and that sometimes a valid limit may be specified for
    a core which is not actually present.
