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 - 2.20 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 800 MHz and 2.20 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.20 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 2200 MHz max turbo 4 active cores 2200 MHz max turbo 3 active cores 2200 MHz max turbo 2 active cores 2200 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: 8468 Duration: 172692 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 9352 Duration: 600103 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 53836 Duration: 8575828 C3: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 25197 Duration: 7332080 C6: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 76 Duration: 40585 C7: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 338105 Duration: 346342830
