I would love to finish this project but I am not sure how. It seems we need to: 1) Evaluate the patches that Baolin suggests as a simpler alternative. 2) Test them in an Android kernel with AAudio MMAP. If you can provide a clear description of the latest set of patches then maybe I can work with someone in-house to test this. I am open to suggestions.
