We can just add the list of interfaces the machine is implementing as an additional parameter to DEFINE_MACHINE, and this solves the problem without adding any boilerplate. Ultimately, we'll need to tag all machines to mention targets supported, so this information has to be written somewhere. Regards, BALATON Zoltan

So hiding boilerplate behind the macro would be ok, thus my proposal. Zoltan, could you please confirm in which way you were qualifying this as boilerplate? See commit f84203a8c22 and if I remember correctly there was some discussion around that on the list where this came from which was partly started by me being annoyed to have half of a device model consiting of just boiler plate. I would not like that to come back if can be avoided as having these macros make the models much more comprehensive for new people not having to go through all the QOM boiler plate to see the actual functionality.

[PATCH 00/11] hw/arm: Define machines as generic QOM types
While DEFINE_MACHINE() is a succinct macro, it doesn't allow registering QOM interfaces to the defined machine. Convert to the generic DEFINE_TYPES() in preparation to register interfaces.
