Intel recommends to use the intel_pstate CPUFreq driver
    in active mode with HWP enabled on Ice Lake and later 
    generations processors. This function allows dynamically 
    setting intel_pstate based on the processor's model.
    For pre-IceLake processors setting pstate to active
    can introduce jitters which were historically seen around
    and tested with RHEL-7.4. From IceLake generation, intel 
    has fixed these issues.
