Hello
since version 6.14.2 new energy is possible with amd-pstate-epp :
you will get status balance_performance , it required
- UEFI option CPPC on
- check with
cpupower frequency-info
analyse du CPU 5 :
driver: amd-pstate-epp
CPUs which run at the same hardware frequency: 5
CPUs which need to have their frequency coordinated by software: 5
energy performance preference: balance_performance
limitation matérielle : 550 MHz - 4.65 GHz
régulateurs disponibles : performance powersave
tactique actuelle : la fréquence doit être comprise entre 1.74 GHz et 4.65 GHz.
Le régulateur "powersave" est libre de choisir la vitesse
dans cette plage de fréquences.
current CPU frequency: 3.56 GHz (asserted by call to kernel)
boost state support:
Supported: yes
Active: yes
amd-pstate limits:
Highest Performance: 166. Maximum Frequency: 4.65 GHz.
Nominal Performance: 132. Nominal Frequency: 3.70 GHz.
Lowest Non-linear Performance: 62. Lowest Non-linear Frequency: 1.74 GHz.
Lowest Performance: 20. Lowest Frequency: 550 MHz.

if you have not amd-pstate or amd-pstate-epp appears ( acpi-cpufreq) ,
you should add on boot command kernel
amd-pstate=active ( with boost) , or passive( without) , or guided ( min/max HW frequency)
