frequency-info -------------- analyzing CPU 0: driver: intel_cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 20.0 us hardware limits: 800 MHz - 1.60 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 1.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.59 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 1600 MHz max turbo 4 active cores 1600 MHz max turbo 3 active cores 1600 MHz max turbo 2 active cores 1600 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 C1E C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 8856 Duration: 134905 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 11566 Duration: 1184264 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 47533 Duration: 7437130 C3: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 220701 Duration: 303714973
