frequency-info -------------- analyzing CPU 0: driver: intel_cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 20.0 us hardware limits: 800 MHz - 1.60 GHz available cpufreq governors: conservative performance schedutil current policy: frequency should be within 800 MHz and 1.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 1.60 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: 9 Available idle states: POLL C1 C1E C3 C6 C7s C8 C9 C10 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 228460 Duration: 747368 C1: Flags/Description: MWAIT 0x00 Latency: 2 Usage: 1543992 Duration: 559574193 C1E: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 1609449 Duration: 314035869 C3: Flags/Description: MWAIT 0x10 Latency: 33 Usage: 9656037 Duration: 19340302518 C6: Flags/Description: MWAIT 0x20 Latency: 133 Usage: 438757 Duration: 229292174 C7s: Flags/Description: MWAIT 0x32 Latency: 166 Usage: 1689923 Duration: 1354655897 C8: Flags/Description: MWAIT 0x40 Latency: 300 Usage: 2545348 Duration: 3656028813 C9: Flags/Description: MWAIT 0x50 Latency: 600 Usage: 7714559 Duration: 46155422806 C10: Flags/Description: MWAIT 0x60 Latency: 2600 Usage: 2139 Duration: 13562538
