If it is this license agreement from Nvidia https://docs.nvidia.com/cuda/eula/index.html Then it is clearly not open source and I would have to recommend against allowing this driver in DPDK. Corollary: without a open-source GPU driver, I would also recommend against including the GPU driver subsystem in DPDK. Note: these views are my own as part of the open-source community and do not represent those of my employer.
