Subject[PATCH v5 03/17] Extend QMP command query-cpus to return accelerator id and model name
Date
The QMP command query-cpus now additionally displays a model name and
the backing accelerator. Both are omitted if the model name is not
initialized.

request:
{ "execute" : "query-cpus" }

answer:
{ { "current": true,
"CPU": 0,
"model": "2827-ga2",
"halted": false,
"accel": "kvm",
"thread_id": 31917
}, ... }
