I'd like to try to go even one step further and mmap both the TS
ringbuffer and a special memory page containing the current DMA

API while allowing trivial-to-implement v3 backward compability.
Hopefully all existing budget cards will support that interface. It
would be a pity if there is some hardware design limitation (for
example broken or ill dma capabilties) that prevents it from using
your proposal.
