Building a Linux GPU Driver for the M4 Mac Mini in One Month

Two developers report building a Linux GPU driver for the M4 Mac Mini in about a month, a driver they describe as fully OpenGL ES 3.0 compliant, using AI agents to run experiments and implement code. Their account shows how human experiment design affected progress: OpenAI's Codex struggled for over a week with a large capture of GPU activity, then advanced after the task was reduced to a small, isolated compute trace.

The developers also used the existing Khronos conformance test suite to guide implementation. It supplied concrete observations and pass-or-fail checks for the agents' work. The result illustrates AI-assisted systems engineering anchored in hardware experiments and tests; the authors say the code needs further testing, human review and refactoring before it can be proposed for upstream integration.
