Track them via pending_flush_bits. Previously WFI was only tracked in flush_bits and WAIT_FOR_ME was emitted directly. This means that we don't emit WAIT_FOR_ME or WAIT_FOR_IDLE if there wasn't a cache flush or other write by the GPU. Also split up host writes from sysmem writes, as only the former require WFI/WAIT_FOR_ME. Along the way, I also realized that we were missing proper handling of transform feedback counter writes which require WAIT_MEM_WRITES. Plumb that through as well. And CmdDrawIndirectByteCountEXT needs a WAIT_FOR_ME as it does not wait for WFI internally. As an example of what this does, a typical barrier for transform feedback with srcAccess = VK_TRANSFORM_FEEDBACK_WRITE_COUNTER_BIT_EXT and dstAccess = VK_ACCESS_INDIRECT_COMMAND_READ_BIT used to emit on A650: - WAIT_FOR_IDLE and now we emit: - WAIT_MEM_WRITES - WAIT_FOR_ME So we've eliminated a useless WFI and added some necessary waits.

`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 `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.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.
