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: 1.40 GHz - 3.40 GHz available frequency steps: 3.40 GHz, 3.00 GHz, 2.60 GHz, 2.30 GHz, 1.90 GHz, 1.40 GHz available cpufreq governors: conservative userspace powersave ondemand performance schedutil current policy: frequency should be within 1.40 GHz and 3.40 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.90 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 2 Total States: 8 Pstate-Pb0: 4000MHz (boost state) Pstate-Pb1: 3700MHz (boost state) Pstate-P0: 3400MHz Pstate-P1: 3000MHz Pstate-P2: 2600MHz Pstate-P3: 2300MHz Pstate-P4: 1900MHz 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: 3547970 Duration: 257051630 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 100 Usage: 1241419 Duration: 1834603909
