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 - 2.00 GHz available frequency steps: 2.00 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz, 800 MHz available cpufreq governors: conservative userspace powersave ondemand performance schedutil current policy: frequency should be within 800 MHz and 2.00 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.00 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 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: 75 Duration: 3585 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 255 Duration: 45513 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x10 Latency: 1 Usage: 4606 Duration: 1418954 C3: Flags/Description: ACPI FFH INTEL MWAIT 0x20 Latency: 17 Usage: 43883 Duration: 184909941
