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 - 2.40 GHz available frequency steps: 2.40 GHz, 2.40 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz, 800 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 800 MHz and 2.40 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 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: 204 Duration: 37456 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 345 Duration: 49099 C2: Flags/Description: ACPI IOPORT 0x1014 Latency: 1 Usage: 78776 Duration: 16362144 C3: Flags/Description: ACPI IOPORT 0x1018 Latency: 162 Usage: 129777 Duration: 245112153
