Pre-bake IBO descriptor sets at the time that images/SSBOs are bound, and re-use the pre-baked descriptors at draw time when we emit state. This starts putting in place the state tracking we'll use when switching over to bindless IBO state, without yet changing the shaders (lowering to bindless) or changing the actual state emitted (other than switching to use the storage descriptor for image reads via isam, like tu does). Note that this even pre-bakes the iova into the descriptor, rather than relying on OUT_RELOC() to do the bo tracking, so we need to manually attach the bo to the ring. But we already require FD_BO_NO_HARDPIN for a6xx. This makes the state emit a straight memcpy, and will simplify things when it comes to generating the bindless descriptor set (which due to the desc_size field in the low bits of the BINDLESS_BASE regs would be awkward to construct as a ring rather than a bo).

`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.
