      Some questions, in case anyone knows:
      1. For GPUs with substantial deep learning capabilities, are they expected to use a different driver for exposing that functionality? If yes, how would that driver interact with the graphics driver/functionality?
      2. Does the new subsystem have a requirement for open source userspace software that can utilize the device?
      3. Does the driver API address cache-coherent device memory (e.g. via CXL), in any explicit way, or have any other functional advantages over using the GPU driver subsystem?
