As a reminder, the same (closed-source) user-space components for OpenGL / OpenCL / Vulkan / CUDA are used regardless of the NVIDIA kernel driver option with their official driver stack.
Right, I'm well aware that that article is the reason why a bunch of people have been making the unsubstantiated claim that Nvidia has hired people to work on Nouveau.
Nvidia hired the former lead Nouveau maintainer and he contributed a bunch of patches a couple of months ago after they hired him. That was his first contribution since stepping down and I'm fairly certain it was his last because there's no way Phoronix would miss the opportunity to milk this some more if they could. He had said when stepping down that he was open to contributing every once in a while, so this wasn't very surprising either way. To be clear, it is not evidence that he or anyone else was hired by Nvidia to work on Nouveau. Otherwise, I'd like to ask what he's been doing since, because that was over three months ago.
