In other words you would do something like -audiohw
<audiodev-args>,model=xxx and it gets desugared automatically to either
-audiodev <audiodev-args>,id=foo -device devname,audiodev=xxx
or
-audiodev <audiodev-args>,id=foo -M propname=foo
Suggestions how to do that in a clean way?
Given that -audiodev is qapi-based I tried it this way:
Since this is sugar, I think it's okay to make it desugar into QAPI,
instead of being QAPI all the way down:
- use qobject_input_visitor_new_str in softmmu/vl.c
- visit the "model" key
- look up the "model", fail if it doesn't match a known model
- pass the rest into a variant of audio_parse_option that takes a
Visitor and returns and Audiodev*
- pass the id into a constructor function keyed by the model
