frequency-info -------------- analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 4.40 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 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: 1.91 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 32528 Duration: 248947 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 5125 Duration: 367559 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 8001 Duration: 1361405 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 2868 Duration: 361085 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 14412 Duration: 9723648 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 51 Duration: 34344 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 10424 Duration: 9527651 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 329 Duration: 2248306 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 15183 Duration: 210495769
