Correct.

DMA of the data through the proposed AQ is supported.

If I understood Max correctly when Max said " This AQ is not aimed for performance ",
he means that AQ doesn't have performance requirements as io/network queues to complete millions of ops/sec.

it is several hundred to maybe (on the higher side) thousand ops/sec during LM, provisioning use case.

DMA perspective as you mentioned, AQ still has the same perf requirements as that of regular nw/blk io queues.
