Constructing the render target store payload is more complex than we can reasonably handle at the NIR level. The main reason is that samplemask and stencil are packed 16-bit and 8-bit parameters, respectively, which are intermixed with other values that are 32-bit. In SIMD32 mode, the packed sub-32-bit values take up fewer registers than normal values. Currently we also don't specialize the NIR for each FS dispatch width, and we can't construct the message descriptor without knowing it. So, we alter nir_intrinsic_store_render_target_intel to take each of the expected parameters - colour, depth, stencil, samplemask, src0_alpha, and discard predicate. We construct the payloads and descriptors in the backend. Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/41688> |

`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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
