it turns out we have explicit control over helper invocations; if a particular bit in the fragment shader descriptor is set, helper invocations are launched; if it clear, they are not. Helper invocations are required whenever computing derivatives, whether explicitly (dFdx/dFdy) *or* implicitly (any texturing). Accordingly, we set this bit when texturing to fix edge case behaviour (literally, haha). Thank you to Jason Ekstrand and Ilia Mirkin for pointing out the representative dEQP test failed along triangle edges and for suggesting helper invocations / derivatives as a list of suspect pieces (which led to discovering the helper invocations enable bit in the first place). Ideally we would use the new NIR analysis pass for this, but that hasn't landed quite yet. Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.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. 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.
