frequency-info -------------- analyzing CPU 10: driver: intel_cpufreq CPUs which run at the same hardware frequency: 10 CPUs which need to have their frequency coordinated by software: 10 maximum transition latency: 20.0 us hardware limits: 800 MHz - 3.20 GHz available cpufreq governors: performance schedutil current policy: frequency should be within 2.25 GHz and 3.20 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.90 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 29: Number of idle states: 4 Available idle states: POLL C1 C1E C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 10314909 Duration: 183928637 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 53300568 Duration: 4048879536 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1204411045 Duration: 254161881645 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 1150873513 Duration: 6084095528129
