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: 800 MHz - 5.50 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 5.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.32 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 5 Available idle states: POLL C1E C6 C8 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 1196432 Duration: 29112876 C1E: Flags/Description: MWAIT 0x01 Latency: 2 Residency: 4 Usage: 10650971 Duration: 1917975814 C6: Flags/Description: MWAIT 0x20 Latency: 220 Residency: 600 Usage: 499006 Duration: 451280499 C8: Flags/Description: MWAIT 0x40 Latency: 280 Residency: 800 Usage: 1543323 Duration: 1996356973 C10: Flags/Description: MWAIT 0x60 Latency: 680 Residency: 2000 Usage: 2203031 Duration: 5795146410
