The +open kernel modules cannot support GPUs before Turing, because the open +kernel modules depend on the GPU System Processor (GSP) first +introduced in Turing. + +"Most features of the Linux GPU driver are supported with the open +flavor of kernel modules, including CUDA, Vulkan, OpenGL, OptiX, and +X11.
