This has been pending for a long time. It is not very consistent to add a significant delay for textures and not do it for UBOs, etc The reason we have not been doing this so far is the accumulated effect on register pressure for V3D as shown by shader-db results below, but from the point of view of a generic scheduler it makes sense to do this. Later patches will address V3D specific issues with register pressure derived from this by letting the driver control its instruction delay settings. total instructions in shared programs: 12662138 -> 13126587 (3.67%) instructions in affected programs: 1813091 -> 2277540 (25.62%) helped: 2410 HURT: 10499 total threads in shared programs: 415858 -> 407208 (-2.08%) threads in affected programs: 17348 -> 8698 (-49.86%) helped: 8 HURT: 4333 total uniforms in shared programs: 3711483 -> 3812698 (2.73%) uniforms in affected programs: 128012 -> 229227 (79.07%) helped: 3474 HURT: 2143 total max-temps in shared programs: 2138763 -> 2318430 (8.40%) max-temps in affected programs: 318780 -> 498447 (56.36%) helped: 588 HURT: 11997 total spills in shared programs: 3860 -> 49086 (1171.66%) spills in affected programs: 709 -> 45935 (6378.84%) helped: 23 HURT: 1595 total fills in shared programs: 5573 -> 55810 (901.44%) fills in affected programs: 1067 -> 51304 (4708.25%) helped: 23 HURT: 1595 LOST: 3 GAINED: 0 Reviewed-by: Alejandro Piñeiro <apinheiro@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15276> |

`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.
