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 maximum transition latency: Cannot determine or is not supported. hardware limits: 400 MHz - 5.18 GHz available cpufreq governors: performance powersave current policy: frequency should be within 2.40 GHz and 5.18 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 2.86 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes AMD PSTATE Highest Performance: 196. Maximum Frequency: 5.18 GHz. AMD PSTATE Nominal Performance: 159. Nominal Frequency: 4.20 GHz. AMD PSTATE Lowest Non-linear Performance: 91. Lowest Non-linear Frequency: 2.40 GHz. AMD PSTATE Lowest Performance: 16. Lowest Frequency: 400 MHz. idle-info --------- CPUidle driver: acpi_idle CPUidle governor: menu analyzing CPU 14: Number of idle states: 4 Available idle states: POLL C1 C2 C3 POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Residency: 0 Usage: 1648 Duration: 46688 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Residency: 2 Usage: 99953 Duration: 6239582 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 18 Residency: 36 Usage: 61754 Duration: 16599584 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 350 Residency: 700 Usage: 64312 Duration: 165334192
