analyzing CPU 0:
driver: intel_pstate
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 0.97 ms.
hardware limits: 1.20 GHz - 2.40 GHz
available cpufreq governors: performance, powersave
current policy: frequency should be within 1.20 GHz and 2.40 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency is 1.28 GHz (asserted by call to hardware).

Error setting new values. Common errors:
- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
