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: 4.0 us hardware limits: 1.40 GHz - 4.00 GHz available frequency steps: 4.00 GHz, 3.00 GHz, 2.50 GHz, 2.00 GHz, 1.40 GHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 1.40 GHz and 4.00 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.52 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes Boost States: 2 Total States: 7 Pstate-Pb0: 4100MHz (boost state) Pstate-Pb1: 3800MHz (boost state) Pstate-P0: 4000MHz Pstate-P1: 3000MHz Pstate-P2: 2500MHz Pstate-P3: 2000MHz 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: 0 Duration: 0 C1: Flags/Description: ACPI HLT Latency: 0 Residency: 0 Usage: 132204 Duration: 18472729 C2: Flags/Description: ACPI IOPORT 0x841 Latency: 100 Residency: 200 Usage: 282006 Duration: 302488174
