Ubuntu: Limited cpupower policy



Question:

So the problem:

$ cpupower frequency-info  analyzing CPU 0:    driver: powernow-k8    CPUs which run at the same hardware frequency: 0 1    CPUs which need to have their frequency coordinated by software: 0 1    maximum transition latency: 109 us    hardware limits: 800 MHz - 2.00 GHz    available frequency steps:  2.00 GHz, 1.80 GHz, 1.60 GHz, 800 MHz    available cpufreq governors: conservative ondemand userspace powersave performance schedutil    current policy: frequency should be within 800 MHz and 800 MHz.                    The governor "ondemand" may decide which speed to use                    within this range.    current CPU frequency: Unable to call hardware    current CPU frequency: 800 MHz (asserted by call to kernel)    boost state support:      Supported: no      Active: no  

You see that the cpu supports up to 2GHz clock, but the policy seems to allow only the lowest 800Mhz, no matter which governor I set.

$ uname -roms  Linux 4.10.0-22-generic x86_64 GNU/Linux  $ lsb_release -a  No LSB modules are available.  Distributor ID: Ubuntu  Description:    Ubuntu 17.04  Release:        17.04  Codename:       zesty  

Is there a way to fix those seemingly incorrect policy limits?
