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: 160 us. hardware limits: 2.00 GHz - 3.00 GHz available frequency steps: 3.00 GHz, 2.67 GHz, 2.33 GHz, 2.00 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 2.00 GHz and 3.00 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.33 GHz. 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: 1692 Duration: 190862 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 57780 Duration: 3885502 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x10 Latency: 1 Usage: 766931 Duration: 218461060 C3: Flags/Description: ACPI FFH INTEL MWAIT 0x30 Latency: 57 Usage: 1085470 Duration: 1789416120
