frequency-info -------------- analyzing CPU 1: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 4.0 us hardware limits: 1.40 GHz - 4.70 GHz available frequency steps: 4.70 GHz, 4.50 GHz, 4.00 GHz, 3.40 GHz, 2.40 GHz, 1.40 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.40 GHz and 4.70 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 3.40 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 1 Total States: 7 Pstate-Pb0: 5000MHz (boost state) Pstate-P0: 4700MHz Pstate-P1: 4500MHz Pstate-P2: 4000MHz Pstate-P3: 3400MHz Pstate-P4: 2400MHz 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: 9 Duration: 466 C1: Flags/Description: ACPI HLT Latency: 0 Usage: 725179 Duration: 8806706 C2: Flags/Description: ACPI IOPORT 0x815 Latency: 100 Usage: 113918 Duration: 383241941
