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 - 4.06 GHz available cpufreq governors: performance powersave current policy: frequency should be within 400 MHz and 4.06 GHz. The governor "powersave" may decide which speed to use within this range. current CPU frequency: Unable to call hardware current CPU frequency: 4.03 GHz (asserted by call to kernel) boost state support: Supported: yes Active: yes AMD PSTATE Highest Performance: 255. Maximum Frequency: 4.06 GHz. AMD PSTATE Nominal Performance: 132. Nominal Frequency: 2.10 GHz. AMD PSTATE Lowest Non-linear Performance: 70. Lowest Non-linear Frequency: 1.11 GHz. AMD PSTATE Lowest Performance: 26. Lowest Frequency: 400 MHz. 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 Usage: 4512411 Duration: 160472426 C1: Flags/Description: ACPI FFH MWAIT 0x0 Latency: 1 Usage: 194578527 Duration: 8518800132 C2: Flags/Description: ACPI IOPORT 0x414 Latency: 18 Usage: 445428819 Duration: 32559348774 C3: Flags/Description: ACPI IOPORT 0x415 Latency: 350 Usage: 33398303 Duration: 323087643896
