This is always set to true for elk platforms. No need for the option. crocus also assumes that we take the sampler path. hasvk had support for both paths (leftover from when the driver still supported Gfx12). We started using HDC messages for indirect UBO access on Tigerlake (Gfx12.x) because of cache reworks that made it more viable. On all prior platforms, we used the sampler because it has additional L1/L2 caches that the dataport lacks. Additionally, Ivybridge and nearby platforms had notoriously slow L3 access in some very common cases. Note that we do use the dataport for constant-offset UBO access, since we can combine many reads into larger block loads.

`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.
