QMP: Add query-hotpluggable-cpus
It will allow mgmt to query present and hotpluggable CPU objects, it is required from a target platform that wishes to support command to implement and set MachineClass.query_hotpluggable_cpus callback, which will return a list of possible CPU objects with options that would be needed for hotplugging possible CPU objects. There are: 'type': 'str' - QOM CPU object type for usage with device_add 'vcpus-count': 'int' - number of logical VCPU threads per CPU object (mgmt needs to know) and a set of optional fields that are to used for hotplugging a CPU objects and would allows mgmt tools to know what/where it could be hotplugged; [node],[socket],[core],[thread] For present CPUs there is a 'qom-path' field which would allow mgmt to inspect whatever object/abstraction the target platform considers as CPU object.
