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 - 2.50 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 1.20 GHz and 2.50 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.49 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 2500 MHz max turbo 4 active cores 2500 MHz max turbo 3 active cores 2500 MHz max turbo 2 active cores 2500 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: 9303 Duration: 63501 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 376829 Duration: 39191723 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 2573594 Duration: 215944570 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 373156 Duration: 110583913 C6: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 1578 Duration: 975901 C7: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 2842433 Duration: 4617203699
