My expectation is that we should remove the host1x-waiter entirely. It
comes from 2011/2012 era of the host1x driver and now duplicates
functionality provided by the dma-fence and drm-scheduler. Perhaps it
could be okay to re-use existing code for the starter, but this is
something to keep in mind that it may be better not to put much effort
into the older code.
Agreed, it should be cleaned up and probably replaced. I made only
minimal changes here to get all my tests working, as I didn't want to do
a full refactoring in this patch series.
