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: 1.20 GHz - 3.30 GHz available cpufreq governors: performance powersave current policy: frequency should be within 1.20 GHz and 3.30 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.20 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 3100 MHz max turbo 4 active cores 3100 MHz max turbo 3 active cores 3100 MHz max turbo 2 active cores 3300 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 271 Duration: 46977 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 516692 Duration: 178204142 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 342558 Duration: 117783922 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 218532 Duration: 89122396 C6: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 249 Duration: 165967 C7: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 923580 Duration: 983074978
