An example when the memory leak happens: requested_size = 4 and alignment = 65536 in anv_slab_bo_alloc: The alloc_size = 65536 and requested = 4 in this case. The group to allocate the entry is the group of size 65536 based on the entry size, while the group to reclaim the entry is the group of size 4 due to the bo->size is registered as the requested_size=4 and used in anv_slab_bo_free. That means, the entry is allocated in group[order of size 65535]->free, moved from group[order of size 65535]->free to the user, and then moved to group[order of size 4]->reclaim, so the entries is accumulated in group[order of size 4]->reclaim and group[order of size 65535] keeps allocating new entries and leading to OOM. The solution is to use `bo->actual_size` to get the group in pb_slab_bo_free using the allocation size. Fixes: |

`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://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ 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://docs.mesa3d.org/bugs.html>`_). Contributing ------------ Contributions are welcome, and step-by-step instructions can be found in our documentation (`docs/submittingpatches.rst <https://docs.mesa3d.org/submittingpatches.html>`_). Note that Mesa uses gitlab for patches submission, review and discussions.
