Sony published a kernel driver for Linux that will be used to support PlayStation hardware like the PlayStation 5 DualSense controller. The driver will allow Linux users to use Sony’s new controller in both Bluetooth and USB mode. [Thanks, Phoronix!]
Previously, Linux users used the official “hid-sony” driver for Sony hardware, but this newest driver release, called “hid-playstation,” will feature additional compatibility. In terms of the PlayStation 5 DualSense controller, functions will include the use of its LEDs, touchpad, battery, motion sensors, lightbar, and rumble feature. Currently, the driver doesn’t offer support for the DualSense’s haptic feedback or adaptive triggers.
The controller was also made available for use recently via Steam following a beta release which added “initial input support.” The Linux driver, which contains about 1,400 lines of code, enables a similar range of features. It is worth noting, however, that the new Linux driver is currently still under review. It is possible to test out the patches ahead of release, though.
Sony’s DualSense controller’s adaptive triggers are a way that developers can create different tactile sensations for the player that correspond with gameplay elements by manipulating the resistance in the trigger buttons. Similarly, haptic feedback is a tactile sensation that communicates in-game information to the player, but it uses precise rumble features to do so.
