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: 1000 MHz - 2.17 GHz available frequency steps: 2.17 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz available cpufreq governors: conservative, userspace, powersave, schedutil, ondemand, performance current policy: frequency should be within 1000 MHz and 2.17 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.17 GHz (asserted by call to hardware). boost state support: Supported: no Active: no idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 146 Duration: 104427 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 1553 Duration: 305018 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x10 Latency: 1 Usage: 68812 Duration: 54145545 C3: Flags/Description: ACPI FFH INTEL MWAIT 0x20 Latency: 17 Usage: 524295 Duration: 226634427
