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: no Active: no Boost States: 0 Total States: 5 Pstate-P0: 1600MHz Pstate-P1: 1400MHz Pstate-P2: 1200MHz Pstate-P3: 1000MHz Pstate-P4: 800MHz 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: ACPI HLT Latency: 0 Usage: 94220 Duration: 16277781 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 400 Usage: 45892 Duration: 384297646
