441 | * machine_set_cpu_numa_node: | |
442 | * @machine: machine object to modify | |
443 | * @props: specifies which cpu objects to assign to | |
444 | * numa node specified by @props.node_id | |
445 | * @errp: if an error occurs, a pointer to an area to store the error | |
446 | * | |
447 | * Associate NUMA node specified by @props.node_id with cpu slots that | |
448 | * match socket/core/thread-ids specified by @props. It's recommended to use | |
449 | * query-hotpluggable-cpus.props values to specify affected cpu slots, | |
450 | * which would lead to exact 1:1 mapping of cpu slots to NUMA node. | |
451 | * | |
452 | * However for CLI convenience it's possible to pass in subset of properties, | |
453 | * which would affect all cpu slots that match it. | |
454 | * Ex for pc machine: | |
455 | * -smp 4,cores=2,sockets=2 -numa node,nodeid=0 -numa node,nodeid=1 \ | |
456 | * -numa cpu,node-id=0,socket_id=0 \ | |
457 | * -numa cpu,node-id=1,socket_id=1 | |
458 | * will assign all child cores of socket 0 to node 0 and | |
459 | * of socket 1 to node 1. | |
460 | * | |
461 | * On attempt of reassigning (already assigned) cpu slot to another NUMA node, | |
462 | * return error. | |
