Qualcomm doesn't release open source drivers for Adreno graphics, so there's that at least. There's a reverse engineering project "freedreno" but I doubt they use that (I don't think it even supports all features). In the ARM SoC space that's quite common (blobs at least for 3D graphics). I don't know if there's something else.
