Most drivers will want nir_opt_barrier_modes() to optimize out unnecessary memory barrier modes. However, virgl has to translate back to GLSL, which means it can really only handle partial memory barriers in compute shaders today, because there isn't a proper way to express them otherwise. Just ask nir_to_tgsi to promote these back to full barriers as a workaround. See KHR-GL43.shader_storage_buffer_object.advanced-readWrite-case1 on virpipe-on-gl as a case where this hack is needed.

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.
