If a program does two blits in a row, we internally do a sequence of
operations that involves binding vb0.
Previously, the vb0 state after each operation would look something like:
| operation | cmd->state.gfx.vb0 | hardware | save->vb0 |
| ---------------------------- | ------------------ | --------- | --------- |
| | user | user | |
| nvk_meta_begin() | user | user | user |
| BindVertexBuffers(internal0) | internal0 | internal0 | user |
| nvk_meta_end() | internal0 | user | |
| nvk_meta_begin() | internal0 | user | internal0 |
| BindVertexBuffers(internal1) | internal1 | internal1 | internal0 |
| nvk_meta_end() | internal1 | internal0 | |
That is, CmdBindVertexBuffers() would update cmd->state.gfx.vb0, but
nvk_meta_end() would not. This meant that the last operation would bind a
driver-internal buffer instead of the original value that the user set.
This change fixes the issue by tracking cmd->state.gfx.vb0 in
nvk_cmd_bind_vertex_buffer(), which both CmdBindVertexBuffers() and
nvk_meta_end() call into.
After this commit, the state looks like:
| operation | cmd->state.gfx.vb0 | hardware | save->vb0 |
| ---------------------------- | ------------------ | --------- | --------- |
| | user | user | |
| nvk_meta_begin() | user | user | user |
| BindVertexBuffers(internal0) | internal0 | internal0 | user |
| nvk_meta_end() | user | user | |
| nvk_meta_begin() | user | user | user |
| BindVertexBuffers(internal1) | internal1 | internal1 | user |
| nvk_meta_end() | user | user | |

`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>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
