The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.67 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: 956 Duration: 30193 C1: Flags/Description: ACPI HLT Latency: 20 Usage: 15179 Duration: 2194644 C2: Flags/Description: ACPI IOPORT 0xf814 Latency: 40 Usage: 30401 Duration: 29466252
