Rather than manipulating job descriptor headers as fat pointers (slow) and using fancy manipulation functions for programatically building the tree in arbitrary orders (slow and complicated) and then having to do a topological sort at runtime every frame (slow) which requires traversing said headers in GPU memory (slow!)... we finally know enough about the hardware to just get things right the first time, or second for next_job linking. So rip out all that code and replace it with a much better routine to create, upload, and queue a job all in one (since now it's the same operation essentially - which is much better for memory access patterns, by the way) and most everything falls into place gracefully according to the rules we've set out. Even wallpapering isn't *so* terrible if you just... move that one little... giant... hack out of sight... ahem.... panfrost_scoreboard_link_batch is no longer a bottleneck, mostly because it no longer exists :-) Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/merge_requests/3836> |

`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.html <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.html <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 `Freenode's #dri-devel <irc://chat.freenode.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.html <https://mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.html <https://mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
