frequency-info -------------- analyzing CPU 4: driver: intel_pstate CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.01 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 5: 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: 17501 Duration: 282672 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 13164 Duration: 1145733 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 28256 Duration: 2619663 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 4490 Duration: 475218 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 16600 Duration: 5894412 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 421 Duration: 352401 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 10506 Duration: 7351419 C9: Flags/Description: MWAIT 0x50 Latency: 480 Usage: 2924 Duration: 5689385 C10: Flags/Description: MWAIT 0x60 Latency: 890 Usage: 41791 Duration: 384091034
