frequency-info -------------- 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: Cannot determine or is not supported. hardware limits: 1.60 GHz - 2.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.60 GHz and 2.80 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.64 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 2800 MHz max turbo 4 active cores 2800 MHz max turbo 3 active cores 2800 MHz max turbo 2 active cores 2800 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 961 Duration: 31000 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 38379 Duration: 8852315 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 128706 Duration: 46099980 C3: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 31190 Duration: 11358784 C6: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 319440 Duration: 809068081
