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: 800 MHz - 3.00 GHz available frequency steps: 3.00 GHz, 2.70 GHz, 2.40 GHz, 2.10 GHz, 1.90 GHz, 1.50 GHz, 1.20 GHz, 800 MHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 3.00 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 800 MHz (asserted by call to hardware) boost state support: Supported: no Active: no Boost States: 0 Total States: 8 Pstate-P0: 4800MHz Pstate-P1: 6400MHz Pstate-P2: 1600MHz Pstate-P3: 3200MHz Pstate-P4: 6400MHz Pstate-P5: 1250MHz Pstate-P6: 450MHz Pstate-P7: 237MHz 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: 1945372 Duration: 363622775 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 100 Usage: 8152736 Duration: 15583227622
