frequency-info -------------- analyzing CPU 2: driver: intel_pstate CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.40 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.79 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 5094 Duration: 139544 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Residency: 4 Usage: 46255 Duration: 9783093 C6: Flags/Description: MWAIT 0x20 Latency: 170 Residency: 500 Usage: 5971 Duration: 3925544 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 600 Usage: 7937 Duration: 6118571 C10: Flags/Description: MWAIT 0x60 Latency: 230 Residency: 700 Usage: 83967 Duration: 363992708
