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: 1.20 GHz - 2.80 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 2.80 GHz and 2.80 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.50 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 2500 MHz max turbo 4 active cores 2700 MHz max turbo 3 active cores 2800 MHz max turbo 2 active cores 2800 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: 176269 Duration: 1985104 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 2148713 Duration: 171089004 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 5606095 Duration: 630082728 C3: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 59251642 Duration: 482833330497 C6 (DISABLED) : Flags/Description: MWAIT 0x20 Latency: 104 Usage: 0 Duration: 0 C7 (DISABLED) : Flags/Description: MWAIT 0x30 Latency: 109 Usage: 0 Duration: 0
