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: Cannot determine or is not supported. hardware limits: 2.20 GHz - 3.60 GHz available frequency steps: 3.60 GHz, 3.20 GHz, 2.20 GHz available cpufreq governors: conservative userspace powersave ondemand performance schedutil current policy: frequency should be within 2.20 GHz and 3.60 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: no Active: no Boost States: 0 Total States: 3 Pstate-P0: 800MHz Pstate-P1: 400MHz Pstate-P2: 500MHz 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: 162256 Duration: 79287097 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 400 Usage: 64727 Duration: 894858222
