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 - 3.10 GHz available frequency steps: 3.10 GHz, 2.80 GHz, 2.40 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 3.10 GHz. The governor "ondemand" 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: yes Boost States: 3 Total States: 8 Pstate-Pb0: 3800MHz (boost state) Pstate-Pb1: 3700MHz (boost state) Pstate-Pb2: 3300MHz (boost state) Pstate-P0: 3100MHz Pstate-P1: 2800MHz Pstate-P2: 2400MHz Pstate-P3: 1900MHz 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: 0 Duration: 0 C1: Flags/Description: <null> Latency: 0 Usage: 51379 Duration: 35876987 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 400 Usage: 33975 Duration: 1348512765
