frequency-info -------------- analyzing CPU 1: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 10.0 us hardware limits: 800 MHz - 2.40 GHz available frequency steps: 2.40 GHz, 2.40 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz, 800 MHz available cpufreq governors: performance schedutil current policy: frequency should be within 800 MHz and 2.40 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 2.40 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 1: 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: 2147 Duration: 88977 C1_ACPI: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 1458 Duration: 93677 C2_ACPI: Flags/Description: ACPI FFH MWAIT 0x10 Latency: 1 Usage: 912260 Duration: 112148290 C3_ACPI: Flags/Description: ACPI FFH MWAIT 0x50 Latency: 162 Usage: 1465340 Duration: 175212273
