For this we add a scoring system that evaluates various aspects of the draw calls in a job. If the cost of the geometry side of the pipeline is too high, then we may pay too high a price in double-buffer mode because with smaller tile size may will probably have more vertex shader invocations in the render and binning stages. On the other hand, if rendering cost is not high enough, we may not have enough rendering work to hide the latency of tile stores in double-buffer mode. Also, because we need to make a decision after we know all the draw calls in a job, but the double-buffer enable bit comes in the TILE_BINNING_MODE_CFG that needs to be emitted first in the binning command list before the draw calls are recorded, if we decide to enable it we need to rewrite that packet and we need to size the tile state properly to account for the extra tiles. For this purpose we delay tile state setup for render pass jobs until we are finishing a job.

`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://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. Remember that not everyone is in the same timezone as you, so it might take a while before someone qualified sees your question. To figure out who you're talking to, or which nick to ping for your question, check out `Who's Who on IRC <https://dri.freedesktop.org/wiki/WhosWho/>`_. The next best option is to ask your question in an email to the mailing lists: `mesa-dev\@lists.freedesktop.org <https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_ Bug reports ----------- If you think something isn't working properly, please file a bug report (`docs/bugs.rst <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
