frequency-info -------------- analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us hardware limits: 800 MHz - 2.20 GHz available frequency steps: 2.20 GHz, 2.20 GHz, 1.60 GHz, 1.20 GHz, 800 MHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.20 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.20 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1_ACPI C2_ACPI C3_ACPI POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 6718 Duration: 264882 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 254 Duration: 8487 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 1 Usage: 64088 Duration: 31542636 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x30 Latency: 57 Usage: 651353 Duration: 316357833
