Some systems have a split render/display architecture: the display side is managed by a KMS driver and the render side is managed by a separate Vulkan driver. Figuring out that these two drivers can work together is not trivial. Currently, the Vulkan renderer tries to find a Vulkan physical device which matches the DRM device's dev_t. On split render/display, there is no such device. The platform bus has historically been abused for situations where no other bus would make sense (e.g. VKMS, evdi). A new "faux" bus has been introduced [1] for such devices, so the platform bus should now be a pretty good hint that all devices are on the same system-on-chip. When we don't find a Vulkan physical device and the DRM device is using the platform bus, fall back to any Vulkan physical which also uses the platform bus.
