But it's not in use. intel_pstate requires Sandy Bridge+ CPU, and this
is Atom N2800. acpu-cpufreq driver is used instead:
# cpupower frequency-info
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 798 MHz - 1.86 GHz
available frequency steps: 1.86 GHz, 1.60 GHz, 1.33 GHz, 1.06 GHz, 798 MHz
available cpufreq governors: conservative, userspace, powersave, ondemand,
performance
current policy: frequency should be within 798 MHz and 1.86 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 798 MHz (asserted by call to hardware).
boost state support:
Supported: no
Active: no
