x86_energy_perf_policy: /dev/cpu/0/msr offset 0x770 read failed: Input

I am trying to set up according to this instruction: https://wiki.archlinux.org/index.php/CP … _governors in Control Intel CPUs energy performance policy
Run command:

x86_energy_perf_policy --hwp-enable

And see error x86_energy_perf_policy: /dev/cpu/0/msr offset 0x770 read failed: Input/output error
And trying turn on

x86_energy_perf_policy --hwp-enable 1

Error x86_energy_perf_policy: EPB not enabled on this platform
My processor intel celeron N4100. Can this EPB be enabled on it?
