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 - 3.90 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.90 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 3: 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: 37459 Duration: 925217 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 186772 Duration: 13893738 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 439962 Duration: 60332712 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 363878 Duration: 51944558 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 1528088 Duration: 733413309 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 14293 Duration: 15711235 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 834503 Duration: 607192251 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 371486 Duration: 579974392 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 1426888 Duration: 6772932789
