Failed to catch the point. :(
What's "query-schema"? Is that a QMP command?
What I meant is that, we can define the following (for example):
{ 'struct': 'GICCapInfo',
'data': [
'version': 'int',
'emulated': 'bool',
'kernel': 'bool'] }
And:
{ 'command': 'query-gic-capability',
'returns': ['GICCapInfo'] }
So we can keep this schema as it is when new versions arrive. We
can just push another element in.
