Linux 7.1 Merges AMD Dynamic EPP Fixes, Intel Bartlett Lake Scaling Fix Written by Michael Larabel in Linux Kernel on 22 May 2026 at 02:50 PM EDT. Add A Comment Merged today for Linux 7.1 was this week's power management fixes with a few notable fixes for both AMD and Intel platforms. Last week I reported on AMD's Dynamic EPP feature for the P-State driver causing some issues for that functionality introduced during the Linux 7.1 merge window. Dynamic Energy Performance Preference (EPP) allows changing the performance profile depending upon whether the Ryzen laptop is running on AC or DC power. EPP values are dynamically adjusted based on the power state and adjust based on plug-in/out events as well as other contributing factors like the ACPI Platform Profile.
