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 - 2.67 GHz available frequency steps: 2.67 GHz, 2.00 GHz available cpufreq governors: userspace, ondemand, performance current policy: frequency should be within 2.00 GHz and 2.67 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 2.00 GHz. boost state support: Supported: no Active: no idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu Analyzing CPU 0: Number of idle states: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 0 Duration: 0 C1: Flags/Description: <null> Latency: 0 Usage: 99573 Duration: 222973994 C2: Flags/Description: <null> Latency: 90 Usage: 0 Duration: 0
