The AMD P-State driver is receiving several new features in Linux 7.1, submitted by AMD's Mario Limonciello. Key additions include CPPC Performance Priority, which lets user-space assign per-core floor performance levels for better thermal/power throttling control via new sysfs attributes. Dynamic Energy Performance Preference (EPP) is also added, enabling automatic EPP profile switching based on AC/DC power state on Ryzen laptops. A Raw EPP feature rounds out the update, allowing fine-grained 0–255 EPP values instead of just four preset options. Bug fixes for PREEMPT_RT real-time kernel builds are also included. The changes are queued for the Linux 7.1 merge window opening in late April.
