507 | * machine_set_cpu_numa_node: | |
508 | * @machine: machine object to modify | |
509 | * @props: specifies which cpu objects to assign to | |
510 | * numa node specified by @props.node_id | |
511 | * @errp: if an error occurs, a pointer to an area to store the error | |
512 | * | |
513 | * Associate NUMA node specified by @props.node_id with cpu slots that | |
514 | * match socket/core/thread-ids specified by @props. It's recommended to use | |
515 | * query-hotpluggable-cpus.props values to specify affected cpu slots, | |
516 | * which would lead to exact 1:1 mapping of cpu slots to NUMA node. | |
517 | * | |
518 | * However for CLI convenience it's possible to pass in subset of properties, | |
519 | * which would affect all cpu slots that match it. | |
520 | * Ex for pc machine: | |
521 | * -smp 4,cores=2,sockets=2 -numa node,nodeid=0 -numa node,nodeid=1 \ | |
522 | * -numa cpu,node-id=0,socket_id=0 \ | |
523 | * -numa cpu,node-id=1,socket_id=1 | |
524 | * will assign all child cores of socket 0 to node 0 and | |
525 | * of socket 1 to node 1. | |
526 | * | |
527 | * On attempt of reassigning (already assigned) cpu slot to another NUMA node, | |
528 | * return error. | |
529 | * Empty subset is disallowed and function will return with error in this case. | |
