frequency-info -------------- analyzing CPU 4: driver: intel_pstate CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 3.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.80 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.60 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 5: Number of idle states: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 245948 Duration: 4963135 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 17115 Duration: 1921514 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 26137 Duration: 5472224 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 5477 Duration: 1517608 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 21937 Duration: 12846485 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 508 Duration: 636215 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 43186 Duration: 426419524
