Linux Kernel Adds Rock Band Guitar Support
The upcoming Linux 7.0 kernel is adding mainline support for Rock Band 4 guitar controllers for the PlayStation 4 and 5. The update reflects the ongoing, community-driven effort to ensure hardware compatibility and interoperability within the open-source ecosystem, often driven by hobbyist and gaming interests.
- The support was added by an independent open-source developer named Rosalie Wanders and merged into the Human Interface Devices (HID) subsystem for the Linux 7.0 kernel. - This kernel-level driver specifically enables support for the PDP RiffMaster and the CRKD Gibson SG guitar controllers, which are designed for Rock Band 4 on the PlayStation 4 and 5. - The patch addresses issues where the controllers weren't mapped correctly and adds support for whammy and tilt functionality by binding them to the left and right triggers. - Prior to this mainline kernel support, using these controllers on Linux often required third-party drivers, community patches, or tools like `RB4InstrumentMapper` which required users to install separate drivers like WinUSB. - This update is part of a larger set of HID changes in Linux 7.0, which also included fixes for Fn lock on ASUS ROG laptops, improved touchpad responsiveness, and support for other various hardware like specific ELECOM mice and multi-touch displays. - The change enables these controllers to be automatically detected and configured through the standard input system, making them usable in games and emulators like Clone Hero and RPCS3 without complex setup. - This contribution highlights the ongoing, community-driven nature of the Linux kernel, which Linus Torvalds started in 1991, where individual developers identify a need and contribute the code to support new hardware.
