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: 0.97 ms. hardware limits: 800 MHz - 2.90 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 800 MHz and 2.90 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 2.89 GHz (asserted by call to hardware). boost state support: Supported: yes Active: yes 2700 MHz max turbo 4 active cores 2700 MHz max turbo 3 active cores 2700 MHz max turbo 2 active cores 2900 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 6 Available idle states: POLL C1-SNB C1E-SNB C3-SNB C6-SNB C7-SNB POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 532 Duration: 251728 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 43450 Duration: 5977881 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 106184 Duration: 50380876 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 18999 Duration: 18671408 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 1379 Duration: 1715168 C7-SNB: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 88385 Duration: 311863098
