Some CTS tests, in particular, dEQP-VK.pipeline.pipeline_library.graphics_library.misc.independent_pipeline_layout_sets.*, do the following: 1. Create a pipeline with a vertex input struct that defines a single attribute pointing to vertex buffer #0, but a vertex shader that doesn't use any attributes. 2. Bind the pipeline, but don't call vkCmdBindVertexBuffers(), then draw. Other drivers handle this just fine because the vertex input registers are never used. However we have an optimization in turnip where we pre-calculate the size of the vertex buffer draw state when the vertex input draw state is bound, which results in a vertex buffer draw state with non-zero size but zero iova, resulting in hangs. While it's questionable whether this is allowed, it's easy enough to just disable the draw state in that case. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/18554>

Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary.
