Greetings Markus,
It is a fair question of which I do not have a nice answer. I am working on fresh atapi-packet-generic engine but it is not a joy. There are oddities like bus-phases or bus-states which their setup and feeding of the DMA engine requires a more eligant hammer.
As much as I hate to concept of a DMA mempool, it looks like the direction to follow. Games such as HOST<>DEVICE || feast<>famine of buffer streams appear to be the norm to push vast amounts of atapi-dma. The alternative is to have device level request queues and have the queues carry the SG or PRD list for that portion.
I am open to suggestions for direction.
Cheers,
Andre Hedrick LAD Storage Consulting Group
