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: 800 MHz - 4.50 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 4.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.84 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: 7 Available idle states: POLL C1 C1E C3 C6 C7s C8 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 279303 Duration: 647119 C1: Flags/Description: MWAIT 0x00 Latency: 2 Residency: 2 Usage: 41141 Duration: 1303229 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Residency: 20 Usage: 15549 Duration: 2580433 C3: Flags/Description: MWAIT 0x10 Latency: 70 Residency: 100 Usage: 5150 Duration: 928692 C6: Flags/Description: MWAIT 0x20 Latency: 85 Residency: 200 Usage: 42181 Duration: 30765540 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Residency: 800 Usage: 189 Duration: 193690 C8: Flags/Description: MWAIT 0x40 Latency: 200 Residency: 800 Usage: 103507 Duration: 379066288
