I thought about that approach as well, but unfortunately it also has a couple of downsides. Especially keeping the exclusive fence set while we actually don't need it isn't really clean either. I'm currently a bit busy with other tasks and so put Nayan on a road to get a bit into the kernel driver (he asked for that anyway). Implementing the simple workaround to sync when we export the DMA-buf should be something like 20 lines of code and fortunately Nayan has an I+A system and so can actually test it. If it turns out to be more problematic or somebody really starts to need it I'm going to hack on that myself a bit more. Regards, Christian.
