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: 800 MHz - 2.80 GHz available frequency steps: 2.80 GHz, 2.20 GHz, 1.50 GHz, 800 MHz available cpufreq governors: ondemand userspace performance schedutil current policy: frequency should be within 800 MHz and 2.80 GHz. The governor "ondemand" 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: yes Boost States: 1 Total States: 5 Pstate-Pb0: 3300MHz (boost state) Pstate-P0: 2800MHz Pstate-P1: 2200MHz Pstate-P2: 1500MHz Pstate-P3: 800MHz 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: 75 Duration: 2966 C1: Flags/Description: ACPI HLT Latency: 0 Usage: 31893133 Duration: 653217275 C2: Flags/Description: ACPI IOPORT 0x514 Latency: 75 Usage: 16998943 Duration: 35712816397
