The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 800 MHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 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: 168 Duration: 126812 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 1892 Duration: 432237 C2: Flags/Description: ACPI IOPORT 0x1014 Latency: 1 Usage: 104440 Duration: 31695029 C3: Flags/Description: ACPI IOPORT 0x1016 Latency: 57 Usage: 104919 Duration: 54658156
