Yuzu is running into a segfault because it writes the push descriptor
twice with 2 different layouts, but without a draw/dispatch in
between.
First vkCmdPushDescriptorSetKHR() writes descriptor 0 & 1 with a
uniform buffer. We toggle the 2 first bits of
anv_descriptor_set::generate_surface_states.
Second vkCmdPushDescriptorSetKHR() writes descriptor 0 with uniform
buffer and descriptor 1 with an image view. The first bit of
anv_descriptor_set::generate_surface_states stays, but the second bit
was already set before and it should now be off.
When we finally flush the push descriptor, we try to generate a
surface state for descriptor 1, but there is no valid buffer view for
it, we access an invalid pointer and segfault.
This fix resets the anv_descriptor_set::generate_surface_states when
the descriptor layout changes.

`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>`_).
