frequency-info -------------- analyzing CPU 4: driver: intel_cpufreq CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: 20.0 us hardware limits: 1.20 GHz - 3.50 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 3.50 GHz and 3.50 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.42 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 3200 MHz max turbo 4 active cores 3300 MHz max turbo 3 active cores 3400 MHz max turbo 2 active cores 3500 MHz max turbo 1 active cores 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 Residency: 0 Usage: 564 Duration: 18030 C1: Flags/Description: MWAIT 0x00 Latency: 1 Residency: 1 Usage: 21151 Duration: 2792495 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 80 Usage: 8069 Duration: 2924070 C3: Flags/Description: MWAIT 0x10 Latency: 59 Residency: 156 Usage: 8784 Duration: 3680154 C6: Flags/Description: MWAIT 0x20 Latency: 82 Residency: 300 Usage: 91746 Duration: 623116143
