The newest code merged overnight for the SDL3 hardware/software abstraction layer is adding basic rumble support for the Valve Steam Deck gaming console handheld.
This merge to the SDL library provides Xbox-style rumble support using the Steam Deck's built-in Xbox-style rumble reporting. The support was contributed by developer Vicki Pfau.
The code was merged into the SDL HIDAPI code for the Steam Deck for SDL 3.0.
