- Linux 7.3 kernel allows per-CPU core granularity for AMD P-State Dynamic EPP instead of a global switch.
- Dynamic EPP is an opt-in feature that lets the kernel autonomously change the Energy Performance Preference (EPP) operating mode.
- The global 'amd_dynamic_epp' module parameter and 'dynamic_epp' sysfs nodes are being removed.
- Per-CPU control is achieved via the 'energy_performance_preference' mode set to 'dynamic' when using the powersave governor.
