Previously the A5XX_SP_FS_OUTPUT_REG_HALF_PRECISION was set depending on whether half_precision was set in the shader key. With support for mediump precision, it is possible to have different outputs use different precisions. That means we can’t have a global shader state to specify it. Instead it now tries to copy the half-float-ness from the nir_variable for the output into the ir3_shader_variant. This is then used to decide whether to set half-precision for each output. The a6xx version is copied from the a5xx code but it has not been tested. v2. [Hyunjun Ko (zzoon@igalia.com)] There's the half flag recently added, which represents precision based on IR3_REG_HALF. Now use this flag to avoid duplication. Signed-off-by: Rob Clark <robdclark@chromium.org> |

`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. 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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses email mailing-lists for patches submission, review and discussions.
