This should avoid some SIMD stalls. I think this special case was added to try to handle this case: First Instruction: WMMA Second Instruction: WMMA instruction with same VGPR of previous WMMA instruction’s Matrix D as Matrix C Stall if the first and second instruction are not the same type of WMMA or use ABS/NEG on SRC2 of the second instruction If I read it correctly, we shouldn't need a delay if the type is the same and no modifier is used. That's kind of complex to handle, so leave it for now. Not inserting any delays likely hurts more than this.

`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.
