We currently only create one queue per queue family on the device. The device can be shared between multiple zink_screens, so having one lock per screen can still lead to multiple locks per queue. Fix this by allocating queue_lock along with the device. This fixes an issue that was causing crashes with nvk+zink and QtWebEngine with QTWEBENGINE_FORCE_USE_GBM=1 This can be reproduced by resizing the window in either: * anki - https://apps.ankiweb.net/ or * Qt's simplebrowser example https://doc.qt.io/qt-6/qtwebengine-webenginewidgets-simplebrowser-example.html which would then cause this dmesg error: nouveau 0000:01:00.0: anki[92007]: Failed to find syncobj (-> in): handle=40 along with a context loss. With VK_LOADER_LAYERS_ENABLE=VK_LAYER_KHRONOS_validation we would additionally get warnings like: Validation Error: [ UNASSIGNED-Threading-MultipleThreads-Write ] | MessageID = 0xa05b236e vkQueueSubmit(): THREADING ERROR : object of type VkQueue is simultaneously used in current thread 139824449189568 and thread 139823901816512 Objects: 1 [0] VkQueue 0x557a666783e0 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>`_).
