I'm not sure "officialise" is a word :) Taking a step back... "info via" and its new QMP counterpart x-query-mos6522-devices dump device state. I understand why examining device state via monitor can be useful for debugging. However, we have more than 2000 devices in the tree. Clearly, we don't want 2000 device state queries. Not even 100. Could we have more generic means instead? We could use QOM (read-only) properties to expose device state. If we use one QOM property per "thing", examining device state becomes quite tedious. Also, you'd have to stop the guest to get a consistent view, and adding lots of QOM properties bloats the code. If we use a single, object-valued property for the entire state, we get to define the objects in QAPI. Differently tedious, and bloats the generated code. We could use a single string-valued property. Too much of an abuse of QOM? We could add an optional "dump state for debugging" method to QOM, and have a single query command that calls it if present. Thoughts?
