tcs_out_lds_offsets is not sure to be 16 byte aligned, it's calculated like this: num_patches * patch_vertices * lshs_vertex_stride num_patches and patch_vertices are not sure to be any value aligned, lshs_vertex_stride is added one extra dword, so it's only 4 byte aligned. This may cause problem even before we switch to nir tess output lower when write tess factor before read tail of input. But it's more likely to cause problem after we switch to nir tess output lower because the main body won't eliminate the low 4bit offset but epilog will, so they use different offset to read/write tess factor.

`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.
