frequency-info -------------- analyzing CPU 2: driver: intel_pstate CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 4.10 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.10 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.00 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 1: 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: 5931 Duration: 89030 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 31947 Duration: 2719917 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 26227 Duration: 3085547 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 15405 Duration: 1947137 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 49819 Duration: 17543866 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 157 Duration: 119607 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 21086 Duration: 12703253 C9: Flags/Description: MWAIT 0x50 Latency: 480 Residency: 5000 Usage: 829 Duration: 1269114 C10: Flags/Description: MWAIT 0x60 Latency: 890 Residency: 5000 Usage: 50887 Duration: 261742495
