* machine_set_cpu_numa_node:

* @machine: machine object to modify
|
|
* @props: specifies which cpu objects to assign to
|
|
* numa node specified by @props.node_id
|
|
* @errp: if an error occurs, a pointer to an area to store the error
|
|
*
|
|
* Associate NUMA node specified by @props.node_id with cpu slots that
|
|
* match socket/core/thread-ids specified by @props. It's recommended to use
|
|
* query-hotpluggable-cpus.props values to specify affected cpu slots,
|
|
* which would lead to exact 1:1 mapping of cpu slots to NUMA node.
|
|
*
|
|
* However for CLI convenience it's possible to pass in subset of properties,
|
|
* which would affect all cpu slots that match it.
|
|
* Ex for pc machine:
|
|
* -smp 4,cores=2,sockets=2 -numa node,nodeid=0 -numa node,nodeid=1 \
|
|
* -numa cpu,node-id=0,socket_id=0 \
|
|
* -numa cpu,node-id=1,socket_id=1
|
|
* will assign all child cores of socket 0 to node 0 and
|
|
* of socket 1 to node 1.
|
|
*
|
|
* On attempt of reassigning (already assigned) cpu slot to another NUMA node,
|
|
* return error.
|
|
* Empty subset is disallowed and function will return with error in this case.
