The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.80 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 1 Total States: 7 Pstate-Pb0: 4300MHz (boost state) Pstate-P0: 4200MHz Pstate-P1: 4100MHz Pstate-P2: 3600MHz Pstate-P3: 2800MHz Pstate-P4: 2000MHz Pstate-P5: 1400MHz 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: 938178 Duration: 369152678 C2: Flags/Description: ACPI IOPORT 0x815 Latency: 100 Usage: 1978028 Duration: 2693702798
