Linux kernel drivers for AMD GPU would work (maybe with a little code meddling), but I seems to me (and I may be wrong) the SoC has too small window for mapping PCIe device address space. GPU cards usually have at least 128MB BAR space, but RK3399 is so tightly stuffed, it seems to support only 64MB. It is enough for something like SATA controller, but not enough for graphic data/buffers.
