frequency-info -------------- analyzing CPU 0: driver: intel_pstate CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: Cannot determine or is not supported. hardware limits: 800 MHz - 3.60 GHz available cpufreq governors: performance powersave current policy: frequency should be within 800 MHz and 3.60 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 3.60 GHz (asserted by call to kernel) boost state support: Supported: no Active: no 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 Usage: 231 Duration: 95226 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 55517 Duration: 7990230 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 22316 Duration: 10258871 C3: Flags/Description: MWAIT 0x10 Latency: 70 Usage: 6101 Duration: 2220155 C6: Flags/Description: MWAIT 0x20 Latency: 85 Usage: 27464 Duration: 22911748 C7s: Flags/Description: MWAIT 0x33 Latency: 124 Usage: 1449 Duration: 1985983 C8: Flags/Description: MWAIT 0x40 Latency: 200 Usage: 57461 Duration: 310405148
