The Intel "ANV" Vulkan driver has begun seeing prep work for enabling a multi-GPU future with multiple Intel graphics processors on the same system. Up to now, the Intel ANV driver has made design assumptions of just having one Intel GPU but now that is being reworked.
The patches merged a few minutes ago begin allowing for multiple adapters and enumerating multiple devices in acknowledging, "What we have now works today because we our GPUs are build into the CPU and so you're guaranteed to only ever have one of them. One day, that will change and we want ANV to be ready."
Beyond the existing Gen12 graphics code that initially came together in 2019, there isn't any new Xe/Gen12 specific code to talk about today but rather these necessary infrastructure changes to make for what is sure to be a very exciting 2020.
