Copilot helps update Linux driver for vintage AMD GPUs

An old open-source Linux driver for AMD's Terascale GPUs has received an update with help from Microsoft's Copilot. The driver, R600 Gallium3D for Mesa, supports the Terascale architecture that debuted with the Radeon HD 2000-series in 2007 and ran through the HD 6000-series three years later.

AMD no longer provides official support for these drivers, so community coders maintain them. Gert Wolny, one of the few still working on R600, used GitHub Copilot to tidy the shader compiler code — a refactoring task that removes duplication and bloated code without changing its fundamental behavior.

Machine learning can quickly spot issues across large codebases, making it well suited to this kind of cleanup. Microsoft also provides a short tutorial on Copilot refactoring for those curious about the process. The update will matter mostly to enthusiasts running vintage hardware on Linux to avoid Windows driver headaches.
