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 - 3.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.80 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.67 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: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 8905 Duration: 18053 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 4909 Duration: 381596 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 4232 Duration: 999765 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 947 Duration: 208122 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 3115 Duration: 1616074 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 81 Duration: 68414 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 2502 Duration: 13319793
