To avoid incompatibility between the compiler implementations used by the driver and the renderer, seq_cst ordering is picked here, which has required a full mfence instruction. Then the renderer side acquire is ensured to be ordered after the cache flush of ring cs updates. Perf wise, there's no regression in headless vkmark runs. In theory, the overhead introduced here weighs trivially as compared to the ring cs encode/decode part. So we should go for better robustness.

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. 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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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.
