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: 1.10 GHz - 2.20 GHz available frequency steps: 2.20 GHz, 1.90 GHz, 1.60 GHz, 1.30 GHz, 1.10 GHz available cpufreq governors: conservative userspace powersave ondemand performance schedutil current policy: frequency should be within 1.10 GHz and 2.20 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.20 GHz (asserted by call to hardware) boost state support: Supported: yes Active: no Boost States: 3 Total States: 8 Pstate-Pb0: 3000MHz (boost state) Pstate-Pb1: 2700MHz (boost state) Pstate-Pb2: 2400MHz (boost state) Pstate-P0: 2200MHz Pstate-P1: 1900MHz Pstate-P2: 1600MHz Pstate-P3: 1300MHz Pstate-P4: 1100MHz 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: ACPI HLT Latency: 0 Usage: 84976 Duration: 29947907 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 400 Usage: 32593 Duration: 595967446
