frequency-info -------------- analyzing CPU 2: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 maximum transition latency: 10.0 us hardware limits: 1.20 GHz - 2.60 GHz available frequency steps: 2.60 GHz, 2.20 GHz, 1.80 GHz, 1.20 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.20 GHz and 2.60 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 1.20 GHz (asserted by call to hardware) idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 2: Number of idle states: 5 Available idle states: POLL C1 C2 C3 C4 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 1188 Duration: 53380 C1: Flags/Description: ACPI HLT Latency: 1 Usage: 267352 Duration: 38315249 C2: Flags/Description: ACPI IOPORT 0x814 Latency: 50 Usage: 36366 Duration: 5225252 C3: Flags/Description: ACPI IOPORT 0x815 Latency: 80 Usage: 19966 Duration: 3573772 C4: Flags/Description: ACPI IOPORT 0x816 Latency: 100 Usage: 491763 Duration: 765883834
