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: 800 MHz - 2.30 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 2.30 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 2.00 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 2000 MHz max turbo 4 active cores 2000 MHz max turbo 3 active cores 2000 MHz max turbo 2 active cores 2300 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-SNB C1E-SNB C3-SNB C6-SNB C7-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 676 Duration: 448381 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 63276 Duration: 14816204 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 62778 Duration: 27065023 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 27332 Duration: 15884319 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 190 Duration: 329853 C7-SNB: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 287455 Duration: 759532413
