frequency-info -------------- analyzing CPU 3: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 3 CPUs which need to have their frequency coordinated by software: 3 energy performance preference: power hardware limits: 400 MHz - 3.80 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 3.80 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 1.40 GHz (asserted by call to kernel) boost state support: Supported: yes Active: no amd-pstate limits: Highest Performance: 196. Maximum Frequency: 5.14 GHz. Nominal Performance: 145. Nominal Frequency: 3.80 GHz. Lowest Non-linear Performance: 42. Lowest Non-linear Frequency: 1.10 GHz. Lowest Performance: 16. Lowest Frequency: 400 MHz. Preferred Core Support: 1. Preferred Core Ranking: 196. idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 4: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 13791 Duration: 559156 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 2 Usage: 209622 Duration: 24412255 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 18 Residency: 36 Usage: 1624092 Duration: 761482930 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 350 Residency: 700 Usage: 1481074 Duration: 2293187139
