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: 600 MHz - 1.50 GHz available frequency steps: 1.50 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz, 800 MHz, 600 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 600 MHz and 600 MHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 600 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: 5 Available idle states: POLL C1 C2 C3 C4 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 393 Duration: 61751 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 281 Duration: 20828 C2: Flags/Description: ACPI IOPORT 0x814 Latency: 1 Usage: 551541 Duration: 3158161207 C3: Flags/Description: ACPI IOPORT 0x815 Latency: 85 Usage: 0 Duration: 0 C4: Flags/Description: ACPI IOPORT 0x816 Latency: 185 Usage: 0 Duration: 0
