Well, that sounds perfect to me; David and Brad have experience of Linux coding, and you have the test and packaging experience. I really want to get into Linux coding, and am quite happy to do the admin and docs as req'd. I think we could both learn some new things :) As you said, David, asm isn't really used, as the goal is portability. It might come in handy once we've got a driver working and we want to improve its latency on a specific platform. (I'm thinking Intel and ARM from my side.) Wrt pages of code per model, I agree with you that hopefully we can get round that, perhaps by having a glue layer to different cards. I don't know, it's been ages since I looked at the code. Have you seen the Echo code, Brad? I'd suggest we make sure we all have a copy, even if we can't post it to a central site, so that we are starting from the same point. We need to classify all the operations that we must provide (the API) and the operations we can build on from the cards. I'd imagine there's a core set.. What do you think? Sounds like you've got a short in there somewhere. Regards, Ranjit.
