Pretty much the answer I expected :), I was just hoping that "wiser and more experienced" minds would say "oh, well to do what you want you should go in this direction". Ah well, such is the life of a kernel hacker. So it sounds like the async dma is the way to go, since I want to off load as much as possible from the core. As you say, though, it's new and not in LDD3. Is .../drivers/dma/dmaengine.c what everyone is refering to as async dma? If not, what is? And what in the kernel is already using it so I can look at some example code. Thanks very much for the pointers Timur.
