The HW can technically execute 16-bit operations, but the restrictions on 16-bit ALU ops are so great that it ends up not being a win for GLES-on-Vulkan to lower mediump to 16-bit operations, at least with the current state of the Intel compiler. This brings zink-on-anv in line with iris and angle-on-anv for mediump behavior (ANGLE uses RelaxedPrecision, which we ignore). Perf on some angle traces on my brya (ADL) and i9-9900K (CFL): ADL zink pubg_mobile_battle_royale: +13.4574% +/- 5.2046% (n=5) CFL zink pubg_mobile_battle_royale: +29.5332% +/- 0.646585% (n=6) ADL zink aztec_ruins_high: +5.78027% +/- 4.80645% (n=4) CFL zink aztec_ruins_high: -1.10641% +/- 0.140562% (n=12) ADL zink trex_200: +5.86956% +/- 2.09633% (n=10) CFL zink trex_200: +9.72136% +/- 0.749261% (n=10) Reviewed-by: Ivan Briano <ivan.briano@intel.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/21775> |

`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.
