    NGG -> Next-Generation Geometry (AMD's marketing term for this combined shader stage)

    TES -> Tessellation Evaluation Shader
    GS -> Geometry Shader
    VS -> Vertex Shader

    GDS -> Global Data Share (An element of AMD's architectures I think is just a part of the cache hierarchy, or a small memory more local than main memory, as opposed to Local Data Share which is smaller and more local still)

    Other than the AMD-specific terms (NGG and GDS), the rest should be found in any OpenGL/Vulkan manual, any introductory 3D graphics textbook or advanced tutorial.

    Yes, probably.

    - Transform feedback is completely emulated with the help of GDS ordered atomics. Transform feedback queries have to be emulated too. (it might still be faster than the previous hw)

    There are too many acronyms. It would be nice to see a proper explanation of the acronyms in the article.

    Phoronix: Radeon Navi Support Pending For RadeonSI OpenGL Driver With 47k Line Worth Of Changes

    Last week AMD posted more than 400 patches providing the AMD Navi support within their AMDGPU DRM kernel driver while this week has brought dozens of patches amounting to 4,293 lines as a patch for their RadeonSI Gallium3D driver in order to provide OpenGL support on these next-gen GPUs being introduced next month as the Radeon RX 5700 series...
