Since we don't normally flush before performing copy transfers, it's possible in some scenarios to use too much memory for staging resources and start failing. This can happen either because we exhaust the total available memory (including system memory virtio-gpu swaps out to), or, more commonly, because the total size of resources in a command buffer doesn't fit in virtio-gpu video memory. To reduce the chances of this happening, force a flush before a copy transfer if the total size of queued staging resources exceeds a certain limit. Since after a flush any queued staging resources will be eventually released, this ensures both that each command buffer doesn't require too much video memory, and that we don't end up consuming too much memory for staging resources in total. Fixes kernel errors reported when running texture_upload tests in glbench. Signed-off-by: Alexandros Frantzis <alexandros.frantzis@collabora.com> Reviewed-by: Chia-I Wu <olvaffe@gmail.com> |

`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 email mailing-lists for patches submission, review and discussions.
