    sandro, i think you are missing the point on pstate driver.
     
    when i use i7z, it may show frequency maxed out at 3.9GHz, but c1 state shows 97 percent of processor is in halt state.
     
    isn't that power saving?
     
    for a long time i had microcode enabled in kernel and would see in dmesg something about microcode driver. 
     
    i assumed it was working but there is more too it.
     
    i use git-sources. i use method two from this page

    i added cpupower to default runlevel with this line in conf.d
     START_OPTS="--governor powersave -d 1000MHz -u 2000MHz"
    and it works.

    Every 5.0s: cat /proc/cpuinfo | grep "MHz"                                                                      Fri Jul 15 18:43:12 2016
     
    cpu MHz         : 3899.902
    cpu MHz         : 3900.329
    cpu MHz         : 3899.902
    cpu MHz         : 3900.115
     
     
    look at documentation - /usr/src/linux/Documentation/cpu-freq/
     
    i disable acpi driver enable pstate and powersave gov and pstate works automatically.  googling pstate - it gets too technical for me.
    i use cpupower frequency info and cpupower frequency set
