AMD is introducing a 'power module' to the AMDGPU Linux kernel graphics driver's Display Core (DC) component. This module, already used in the Windows Radeon driver, will manage panel power features including backlight control, Panel Self Refresh (PSR), and replay functionality. The change aims to unify code paths between Linux and Windows, improving display power savings on AMD hardware — particularly for laptops. The patches were posted to the mailing list but missed the Linux 7.1 cycle, targeting Linux 7.2 instead.
