One of the things I'm interested in is to use a memcpy capable DMA engine HW to optimize user space and kernel space parameter copying.
Of course, this will not be viable for all parameter sizes but I can see this being useful. The goal is to save power in the cost of little performance.
Before I go and invent my own mechanism, I'd like to have ideas on what an acceptable solution would look like. Especially, I'm looking for a generic implementation that could plug into any DMA engine HW.
