Since that uio driver required patching the kernel, and the kernel maintainer of UIO didn't want that patch, that work was abandoned. The intention is to use VFIO in no-IOMMU mode instead. Once VFIO with no-IOMMU is working, I will rework the virtio (and vmxnet3) changes to support that. If you want to help or do it your self, I can send the old code.
