The governor "conservative" may decide which speed to use within this range. current CPU frequency: 1.40 GHz (asserted by call to hardware) boost state support: Supported: yes Active: no Boost States: 2 Total States: 8 Pstate-Pb0: 2800MHz (boost state) Pstate-Pb1: 2300MHz (boost state) Pstate-P0: 1900MHz Pstate-P1: 1800MHz Pstate-P2: 1700MHz Pstate-P3: 1600MHz Pstate-P4: 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: 1214 Duration: 81784 C1: Flags/Description: ACPI HLT Latency: 0 Usage: 483096 Duration: 209779040 C2: Flags/Description: ACPI IOPORT 0x841 Latency: 100 Usage: 1666411 Duration: 3434543510
