SSBO access works very differently from UBO access. Straddling
loads/stores isn't an issue, loads/stores instead must be aligned to the
element size and can have up to 4 components.
We support 16-bit access with SSBOs on a650+, and sometimes the
vectorizer tries to create a misaligned 32-bit access when combining
32-bit and 16-bit accesses. The UBO-focused logic didn't reject this,
which is now fixed. This fixes a number of VK-CTS regressions on a650+.
Fixes: bf49d4a084 ("freedreno/ir3: Enable load/store vectorization for SSBO access, too.")

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.
