How do I change the cpufreq policy range?$ cpupower frequency-infoanalyzing 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: noYou can see that hardware limit is at 2GHz, but policy limit is at 800. Trying$ sudo cpupower frequency-set --max 2000000 Setting cpu: 0Setting cpu: 1but without effect:$ cpupower frequency-info --policyanalyzing CPU 0:  current policy: frequency should be within 800 MHz and 800 MHz.                  The governor ondemand may decide which speed to use                  within this range.I've tried echoing the values directly:echo 2000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freqno dice.The issue happens on xubuntu 17.04 x86_64 and on latest Majnaro i686, so I don't believe it's distro specific.
