There will be PCIe controllers in the initial configurations, and typically in most others as well; our config software and process lets the uncore be configured to suit the application, and not all applications need them. We do not anticipate configuring any graphics capability directly on the initial chips; it’s not our expertise. Later on, possibly, if resources permit and markets demand.
We expect to port software support for most industry-standard interfaces, likely including OpenGL. As for others, it’s too soon to sketch out a path.
