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 - 2.27 GHz available frequency steps: 2.27 GHz, 2.27 GHz, 1.60 GHz, 800 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 800 MHz and 2.27 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 800 MHz (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: 797 Duration: 167267 C1: Flags/Description: ACPI FFH INTEL MWAIT 0x0 Latency: 1 Usage: 8610 Duration: 777282 C2: Flags/Description: ACPI FFH INTEL MWAIT 0x10 Latency: 1 Usage: 617634 Duration: 285364140 C3: Flags/Description: ACPI FFH INTEL MWAIT 0x50 Latency: 162 Usage: 1182789 Duration: 3309263086
