NVIDIA Exploring Ways To Better Support An Upstream Kernel Driver
Here's how an exciting message from a NVIDIA engineer that just hit the mailing list begins: 'NVIDIA has been exploring ways to better support the effort for an upstream kernel mode driver for GPUs that are capable of running GSP-RM firmware, since the introduction to Nova.'
Use cases have been identified for which separating the core GPU programming out of the full DRM driver stack is a strong requirement from our key customers. A core driver would be responsible for booting and communicating with GSP-RM, enumeration of HW configuration, shared/partitioned resource management, exception handling, and event dispatch. As Nouveau's KMD is already split (in the logical sense) along similar lines, we're using it here for the purposes of this RFC to demonstrate the feasibility of such an architecture, and open it up for discussion."
