frequency-info -------------- analyzing CPU 4: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 4 CPUs which need to have their frequency coordinated by software: 4 energy performance preference: balance_performance hardware limits: 400 MHz - 4.21 GHz available cpufreq governors: performance powersave current policy: frequency should be within 2.39 GHz and 4.21 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 3.11 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes amd-pstate limits: Highest Performance: 255. Maximum Frequency: 4.21 GHz. Nominal Performance: 218. Nominal Frequency: 3.60 GHz. Lowest Non-linear Performance: 145. Lowest Non-linear Frequency: 2.39 GHz. Lowest Performance: 25. Lowest Frequency: 400 MHz. Preferred Core Support: 0. Preferred Core Ranking: 255. idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 10: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 1321 Duration: 45935 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 2 Usage: 51258 Duration: 8650670 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 18 Residency: 36 Usage: 114073 Duration: 45423326 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 350 Residency: 700 Usage: 149980 Duration: 363692793
