frequency-info -------------- analyzing CPU 3: driver: intel_pstate CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 3.50 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 900 MHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 4: 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 Residency: 0 Usage: 25772 Duration: 721268 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 8220 Duration: 678406 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 16354 Duration: 3025744 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 6509 Duration: 1648112 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 20849 Duration: 10639605 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 196 Duration: 308459 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 10268 Duration: 8772584 C9: Flags/Description: MWAIT 0x50 Latency: 480 Residency: 5000 Usage: 1570 Duration: 4944536 C10: Flags/Description: MWAIT 0x60 Latency: 890 Residency: 5000 Usage: 25174 Duration: 294838306
