Christian, do you see anything which could prevent the solution I
outlined from working?
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.
