RISC-V has GPU vector extension in order to build "shader" cores. But this is not a hardware 3D pipeline. In theory, the hardware 3D pipeline should be programmed "à la" vulkan: hardware queues of commands (3D/compute/DMA). But as far as I know, we don't have something like ahci or nvme or usb xhci for that... yet.
