If we can entirely push uniform data, we don't need a SURFACE_STATE descriptor for pulling data. Since constant uploads are a very common operation, and being able to push all data is also very common, we would like to avoid the overhead in this case. This patch defers uploading new descriptors. Instead of handling that at iris_set_constant_buffer, we do it at iris_update_compiled_shaders, where we can see the currently bound shader variants. If any need pull descriptors, and descriptors are missing, we update them and flag that the binding table also needs to be refreshed. Improves performance in GFXBench5 gl_driver2 on an i7-6770HQ by 31.9774% +/- 1.12947% (n=15). Reviewed-by: Caio Marcelo de Oliveira Filho <caio.oliveira@intel.com> |

`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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 `Freenode's #dri-devel <irc://chat.freenode.net#dri-devel>`_, someone will redirect you if necessary.
