- gen4 - has dp4acc and dp2acc, dp4acc is used to implement 4x8 dot product. - gen3 - has dp2acc, in OpenCL blob uses dp2acc for dot product on both get3 and gen4. - gen2 - unknown, lower everything. - gen1 - no dp2acc, lower everything. OpenCL blob doesn't advertise cl_qcom_dot_product8 but still generates code for it. The assembly is more verbose and uses yet to be documented mad32.u16 instruction. Passes: dEQP-VK.spirv_assembly.instruction.compute.opsdotkhr.* dEQP-VK.spirv_assembly.instruction.compute.opudotkhr.* dEQP-VK.spirv_assembly.instruction.compute.opsudotkhr.* dEQP-VK.spirv_assembly.instruction.compute.opsdotaccsatkhr.* dEQP-VK.spirv_assembly.instruction.compute.opudotaccsatkhr.* dEQP-VK.spirv_assembly.instruction.compute.opsudotaccsatkhr.* Only packed 4x8 unsigned and mixed versions are accelerated. However in theory we should be able to do better for signed version than current NIR lowering.

`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.
