That said, the business model as described by IBM's Red Hat may well comply with the GPL — it's just so murky that any tweak to the model in any direction seems to definitely violate, in our experience.

• M1 Mesa Driver Upstreamed — I’ve begun a Gallium driver for the M1, implementing much of the OpenGL 2.1 and ES 2.0 specifications. With the compiler and driver together, we’re now able to run OpenGL workloads like glxgears and scenes from glmark2 on the M1 with an open-source stack. To top it off, the compiler and driver are now upstreamed in Mesa!
