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 - 2.50 GHz available frequency steps: 2.50 GHz, 2.30 GHz, 2.10 GHz, 1.90 GHz, 1.60 GHz, 1.20 GHz, 800 MHz available cpufreq governors: conservative ondemand userspace powersave performance schedutil current policy: frequency should be within 800 MHz and 2.50 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 800 MHz (asserted by call to hardware) boost state support: Supported: yes Active: yes Boost States: 1 Total States: 8 Pstate-Pb0: 1600MHz (boost state) Pstate-P0: 3200MHz Pstate-P1: 6400MHz Pstate-P2: 3200MHz Pstate-P3: 6400MHz Pstate-P4: 850MHz Pstate-P5: 450MHz Pstate-P6: 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: 558313 Duration: 131902086 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 100 Usage: 1267092 Duration: 8261874195
