This adds the following template options:
- add an option to fill TC set_vertex_buffers from st_update_array directly
(always true without u_vbuf, so always used with radeonsi)
- add an option saying that there are no zero-stride attribs
- add an option saying that there are no user buffers
(always true with glthread, so always used with radeonsi)
- add an option saying that there is an identity mapping between vertex
buffers and vertex attribs
I have specifically chosen those options because they improve performance.
I also had other options that didn't, like unrolling the setup_arrays loop.
This adds a total of 42 variants of st_update_array_templ for various cases.
Usually only a few of them are used in practice.
Overhead of st_prepare_draw in VP2020/Catia:
Before: 8.5% of CPU used
After: 6.13% of CPU used
That's 2.37% improvement. Since there are 4 threads using the CPU and
the percentage includes all threads in the system, the improvement for
the GL thread is about 8% (roughly 2.17% * 4; each thread at 25% of global
utilization means 100% utilization in 4 cores).

`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.
