Hi Pierre-Louis
That said, do we want to preclude it? at some point we probably want to get rid of the FE/BE distinction and have 'domains' that can be chained. So it may not be a good thing to cast a restriction in stone. If at some point we need a list of upstream/downstream clients maybe we should keep this.
Yeah, "domains" is nice idea !!
But, before that, I think we need to cleanup soc-pcm. I'm reading it, but it is too much complex, and too unreadable... I want to cleanup it first. I believe it can help the conversion (= FE/BE to domains).
The idea of domains/constraint propagation is not mine BTW, it was presented by Lars some 2-3 years ago. there may be a note somewhere in the audio miniconference minutes.
Yes, I guess it was ELC-E. My work (*) is to helpping him/his idea.

Thank you for your help !! Best regards --- Kuninori Morimoto
