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: 1000 MHz - 1.83 GHz available frequency steps: 1.83 GHz, 1.33 GHz, 1000 MHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 1000 MHz and 1.83 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.83 GHz (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: 1134 Duration: 680172 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 4275 Duration: 275240 C2: Flags/Description: ACPI IOPORT 0x1014 Latency: 1 Usage: 361371 Duration: 324059183 C3: Flags/Description: ACPI IOPORT 0x1016 Latency: 57 Usage: 6040780 Duration: 61419977389
