it looks like I'm a step further understanding the problems which come with this change.
I've more or less audited all use cases and think that only i915 is left with the following lock inversion: https://intel-gfx-ci.01.org/tree/drm-tip/Patchwork_9705/fi-cfl-8700k/igt@gem_mmap_gtt@xxxxxxxxxxxxxxxxxxxxxxxxxx
Now my question is what is &obj->mm.lock used for and why do you guys call dma_buf_map_attachment() while holding it?
Thanks in advance, Christian. _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
