I think we'd want to change wl_drm to have a copy of the callbacks. As-is one could get a crash racing dlclose of libEGL (or friends) while any of the callbacks are still used. I'm assuming that's one of the reasons we have the wl_drm::wl_buffer_interface instance. -Emil _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
