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 - 2.60 GHz available frequency steps: 2.60 GHz, 2.30 GHz, 2.00 GHz, 1.80 GHz, 1.60 GHz, 1.30 GHz, 1000 MHz, 800 MHz available cpufreq governors: conservative userspace powersave ondemand performance schedutil current policy: frequency should be within 800 MHz and 2.60 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 2.60 GHz (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: 4800MHz Pstate-P4: 850MHz 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: 22900 Duration: 2978642 C2: Flags/Description: ACPI IOPORT 0x1771 Latency: 100 Usage: 22384 Duration: 44264527
