frequency-info -------------- analyzing CPU 2: driver: amd-pstate-epp CPUs which run at the same hardware frequency: 2 CPUs which need to have their frequency coordinated by software: 2 energy performance preference: balance_performance hardware limits: 400 MHz - 4.47 GHz available cpufreq governors: performance powersave current policy: frequency should be within 2.37 GHz and 4.47 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: 4.16 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes amd-pstate limits: Highest Performance: 166. Maximum Frequency: 4.47 GHz. Nominal Performance: 145. Nominal Frequency: 3.90 GHz. Lowest Non-linear Performance: 88. Lowest Non-linear Frequency: 2.37 GHz. Lowest Performance: 15. Lowest Frequency: 400 MHz. Preferred Core Support: 1. Preferred Core Ranking: 171. idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 3: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 1807 Duration: 47504 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 2 Usage: 19999 Duration: 2375405 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 18 Residency: 36 Usage: 32865 Duration: 10719383 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 350 Residency: 700 Usage: 64662 Duration: 404565385
