frequency-info -------------- analyzing CPU 1: driver: intel_cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 20.0 us hardware limits: 800 MHz - 2.70 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.70 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.38 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes 2500 MHz max turbo 4 active cores 2500 MHz max turbo 3 active cores 2500 MHz max turbo 2 active cores 2700 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 6 Available idle states: POLL C1 C1E C3 C6 C7 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 13774 Duration: 245791 C1: Flags/Description: MWAIT 0x00 Latency: 1 Usage: 33161 Duration: 3652294 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 91983 Duration: 26439966 C3: Flags/Description: MWAIT 0x10 Latency: 59 Usage: 53729 Duration: 21201285 C6: Flags/Description: MWAIT 0x20 Latency: 80 Usage: 3903 Duration: 3149957 C7: Flags/Description: MWAIT 0x30 Latency: 87 Usage: 668534 Duration: 2636300819
