So I think we do want these branches for coherent vs non-coherent as they have very different semantics and I do not think that hiding them under the same API helps people to understand those vastly different semantics. OTOH we should look into a fallback for DMA API instances that do not support the discontigous allocations. I think between your comments and those from Ricardo I have a good idea for a somewhat updated API. I'll try to post something in the next days.Did you have time to look into this? No hurry, I just want to make sure that I didn't miss anything ;)
Haven't managed to get to it, sorry.
