How does this differ from the "intel_gna" driver being proposed here: https://lore.kernel.org/linux-doc/20210513110040.2268-1-maciej.kwapulinski@linux.intel.com/ Please work together to come up with a unified userspace api for these devices, and hopefully, shared kernel code as well. thanks, greg k-h
