--- Comment #21 from Raymond Auge ---
Ok this seems to give working governance (2 levels only powersave, performance)
and I'm apparently seeing CPU frequencies beyond those previously available,
which were 800MHz-2000MHz
Now I see:
~]$ sudo dmidecode -t processor | grep MHz
External Clock: 100 MHz
Max Speed: 4000 MHz
Current Speed: 2000 MHz
and the cpu speed in powersave hovers around:
~]$ grep MHz /proc/cpuinfo
cpu MHz : 1553.320
cpu MHz : 1560.644
cpu MHz : 2186.230
cpu MHz : 1757.519
