frequency-info -------------- analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 4.0 us hardware limits: 1.30 GHz - 2.50 GHz available frequency steps: 2.50 GHz, 2.30 GHz, 2.10 GHz, 1.90 GHz, 1.60 GHz, 1.30 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.30 GHz and 2.50 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.10 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 2 Total States: 8 Pstate-Pb0: 2900MHz (boost state) Pstate-Pb1: 2700MHz (boost state) Pstate-P0: 2500MHz Pstate-P1: 2300MHz Pstate-P2: 2100MHz Pstate-P3: 1900MHz Pstate-P4: 1600MHz Pstate-P5: 1300MHz 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: 12 Duration: 343 C1: Flags/Description: ACPI HLT Latency: 0 Usage: 254644 Duration: 74440562 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 400 Usage: 56208 Duration: 145988465
