Ok, I can redo and use specific types, but there still is a problem of how do we configure a pipeline (a collection of widgets, where several pipelines can make a path from PCM to DAI). This configuration data is not hw/sw params type data, but more DSP scheduling type data. My original thought was the pipeline widget, as there is nothing else that cleanly fits into the ABI and that the pipeline scheduling data is DAPM widget/graph related anyway.
Another alternative is extending the topology ABI and introduce a pipeline object that would be ignore by the core and just used by certain drivers and firmwares ?
I think I'm tending towards having a scheduler widget now (instead of a pipeline widget) and that would be a valid part of the graph and also discoverable via debugfs etc.
