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 - 2.20 GHz available cpufreq governors: performance, powersave current policy: frequency should be within 800 MHz and 2.20 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency is 1.28 GHz (asserted by call to hardware). boost state support: Supported: no Active: no 25500 MHz max turbo 4 active cores 25500 MHz max turbo 3 active cores 25500 MHz max turbo 2 active cores 25500 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: 119 Duration: 47503 C1-SNB: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 11269 Duration: 3359612 C1E-SNB: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 26225 Duration: 24744889 C3-SNB: Flags/Description: MWAIT 0x10 Latency: 80 Usage: 3208 Duration: 5566571 C6-SNB: Flags/Description: MWAIT 0x20 Latency: 104 Usage: 148 Duration: 533928 C7-SNB: Flags/Description: MWAIT 0x30 Latency: 109 Usage: 12652 Duration: 56130536
