Could we use a smaller DMA length so that we get more DMA0 interrupts?
That would allow us to update the latency more often, rather than once per
block. I think. I'm not looking at the code right now and I have a
sketchy understanding at best anyway

(Note I'm not suggesting we change the blocksize, just that we set program
the DMA length to be MIN( length, SMALL ) where SMALL could be 1024 for
example).
