frequency-info -------------- analyzing CPU 3: driver: intel_cpufreq CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: 20.0 us hardware limits: 1.20 GHz - 1.70 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.20 GHz and 1.70 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.20 GHz (asserted by call to kernel) boost state support: Supported: no Active: no idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 4: Number of idle states: 5 Available idle states: POLL C1 C1E C3 C6 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 11469411 Duration: 195587735 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 67781085 Duration: 4710171828 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 98663561 Duration: 9813274063 C3: Flags/Description: MWAIT 0x10 Latency: 40 Usage: 145543565 Duration: 123754753449 C6 (DISABLED) : Flags/Description: MWAIT 0x20 Latency: 133 Usage: 0 Duration: 0
