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 - 3.10 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 3.10 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.09 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 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: 35140 Duration: 420716 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 47094 Duration: 7818033 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 127013 Duration: 25603133 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 81713 Duration: 36934912 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 363347 Duration: 577486007
