    SubjectRe: [RFT][PATCH 0/2] cpufreq: intel_pstate: Handle _PPC updates on global turbo disable/enable
    Hi,

    I applied these patches on top of 4.20. The max frequency of all the
    cores now reflects the actual value and it's updated whenever I
    change the power source.

    Regards,
    Gabriele
