I've seen an absurd number of people (including myself) complaining about problems with DMA overruns, DMA not being able to grab memory below 16meg, DMA not properly allocated, etc., and it seems to me that part of this is due to the fact that every kernel module that uses DMA has to PROGRAM THE DMA CHIP ITSELF!
Perhaps it would be a good idea to consolidate all this into a set of kernel functions to access DMA. That way DMA would only be handled in one place...resulting in fewer DMA-related bugs.
Has this been suggested before? Has anyone worked on it? Is there any reason this might be a bad idea?
