frequency-info -------------- analyzing CPU 3: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 maximum transition latency: 4.0 us hardware limits: 1.10 GHz - 2.10 GHz available frequency steps: 2.10 GHz, 1.80 GHz, 1.50 GHz, 1.10 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.10 GHz and 2.10 GHz. The governor "schedutil" may decide which speed to use within this range. current CPU frequency: 1.10 GHz (asserted by call to hardware) boost state support: Supported: yes Active: no Boost States: 3 Total States: 8 Pstate-Pb0: 2900MHz (boost state) Pstate-Pb1: 2600MHz (boost state) Pstate-Pb2: 2400MHz (boost state) Pstate-P0: 2100MHz Pstate-P1: 1800MHz Pstate-P2: 1500MHz Pstate-P3: 1100MHz idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 3: Number of idle states: 3 Available idle states: POLL C1 C2 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1 Duration: 60 C1: Flags/Description: ACPI HLT Latency: 0 Usage: 175509 Duration: 28534319 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 100 Usage: 285806 Duration: 955307869
