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 - 1.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 1.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 1.18 GHz (asserted by call to hardware) boost state support: Supported: no Active: no 25500 MHz max turbo 4 active cores 25500 MHz max turbo 3 active cores 25500 MHz max turbo 2 active cores 25500 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1-SNB C1E-SNB C3-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 121 Duration: 30988 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 6091 Duration: 1372412 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 13039 Duration: 8340904 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 65023 Duration: 257836927
