frequency-info -------------- analyzing CPU 0: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.55 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.10 GHz and 4.55 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.45 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes AMD PSTATE Highest Performance: 191.
