Matthias,
I've just reached the point where it's obvious that our design must use DMA. This is a significant setback as writing a custom DMA driver is going to impact our timescales quite badly. My knowledge of PCIe transactions is negligible, so we are looking for additional expertise in this area. It's a shame that there is no generic solution from Altera and that every user must make their own solution from scratch.

Oliver, you said "Unfortunately, as others have warned, it's really slow!".
Is it fast enough?
Once you get your head round the MM address translation tables DMA functionality with the MM interface is fairly straight forward.
