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 - 2.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 2.80 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.55 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: 8 Available idle states: POLL C1 C1E C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 540 Duration: 18333 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 28839 Duration: 2174744 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 36587 Duration: 5682770 C6: Flags/Description: MWAIT 0x20 Latency: 150 Usage: 0 Duration: 0 C7s: Flags/Description: MWAIT 0x31 Latency: 150 Usage: 194574 Duration: 114726945 C8: Flags/Description: MWAIT 0x40 Latency: 5636 Usage: 531 Duration: 503875 C9: Flags/Description: MWAIT 0x50 Latency: 5636 Usage: 5767 Duration: 12988577 C10: Flags/Description: MWAIT 0x60 Latency: 5963 Usage: 50309 Duration: 249564917
