The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.33 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: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 345 Duration: 61166 C1: Flags/Description: ACPI HLT Latency: 20 Usage: 61362 Duration: 40245819 C2: Flags/Description: ACPI IOPORT 0xf814 Latency: 40 Usage: 114070 Duration: 530835548
