    Subject[PATCH v3 2/2] cpufreq: CPPC: Change FIE default
    Date
    FIE is mostly implemented as PCC mailboxes on arm machines.  This was
    enabled by default without any data suggesting that it does anything
    but hurt system performance. Lets change the default to 'n' until
    hardware appears which clearly benefits.

    This extends frequency invariance support in the CPPC cpufreq driver,
    by using CPPC delivered and reference performance counters.
