frequency-info -------------- analyzing CPU 1: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 1 CPUs which need to have their frequency coordinated by software: 1 maximum transition latency: 4.0 us hardware limits: 1.40 GHz - 4.10 GHz available frequency steps: 4.10 GHz, 3.00 GHz, 2.60 GHz, 1.90 GHz, 1.40 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.40 GHz and 4.10 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.51 GHz (asserted by call to kernel) boost state support: Supported: yes Active: no Boost States: 3 Total States: 8 Pstate-Pb0: 4100MHz (boost state) Pstate-Pb1: 4100MHz (boost state) Pstate-Pb2: 4100MHz (boost state) Pstate-P0: 4100MHz Pstate-P1: 3000MHz Pstate-P2: 2600MHz Pstate-P3: 1900MHz Pstate-P4: 1400MHz 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 Residency: 0 Usage: 3 Duration: 116 C1: Flags/Description: ACPI HLT Latency: 0 Residency: 0 Usage: 587207 Duration: 123064221 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 400 Residency: 800 Usage: 162148 Duration: 211186902
