[Qemu-devel] [PATCH 0/3] qmp: query-host-cpu command

[Eduardo Habkost]

Add QMP command to allow management software to query for
CPU information for the running host.

The data returned by the command is in the form of a dictionary
of QOM properties.

This series depends on the "Add runnability info to
query-cpu-definitions" series I sent 2 weeks ago.

Example output for x86:
