Currently, there is only a local work\nqueue for one graph to walk. We introduce a scheduler worker queue in\neach worker core for dispatching tasks. It will perform the walk on\nscheduler work queue first, then handle the local work queue.\n\nSigned-off-by: Haiyue Wang <haiyue.wang@intel.com>\nSigned-off-by: Cunming Liang <cunming.liang@intel.com>\nSigned-off-by: Zhirun Yan <zhirun.yan@intel.com>\n---\n lib/graph/rte_graph_model_dispatch.h | 42 ++++++++++++++++++++++++++++\n 1 file changed, 42 insertions(+)", "diff": "diff --git a/lib/graph/rte_graph_model_dispatch.h b/lib/graph/rte_graph_model_dispatch.h\nindex 7cbdf2fdcf..764c4ecfd0 100644\n--- a/lib/graph/rte_graph_model_dispatch.h\n+++ b/lib/graph/rte_graph_model_dispatch.h\n@@ -71,6 +71,48 @@ __rte_experimental\n int rte_graph_model_dispatch_lcore_affinity_set(const char *name,\n \t\t\t\t\t\tunsigned int lcore_id);\n \n+/**\n+ * Perform graph walk on the circular buffer and invoke the process function\n+ * of the nodes and collect the stats.\n+ *\n+ * @param graph\n+ * Graph pointer returned from rte_graph_lookup function.\n+ *\n+ * @see rte_graph_lookup()\n+ */\n+__rte_experimental\n+static inline void\n+rte_graph_walk_mcore_dispatch(struct rte_graph *graph)\n+{\n+\tconst rte_graph_off_t *cir_start = graph->cir_start;\n+\tconst rte_node_t mask = graph->cir_mask;\n+\tuint32_t head = graph->head;\n+\tstruct rte_node *node;\n+\n+\tif (graph->wq != NULL)\n+\t\t__rte_graph_sched_wq_process(graph);\n+\n+\twhile (likely(head != graph->tail)) {\n+\t\tnode = (struct rte_node *)RTE_PTR_ADD(graph, cir_start[(int32_t)head++]);\n+\n+\t\t/* skip the src nodes which not bind with current worker */\n+\t\tif ((int32_t)head < 0 && node->lcore_id != graph->lcore_id)\n+\t\t\tcontinue;\n+\n+\t\t/* Schedule the node until all task/objs are done */\n+\t\tif (node->lcore_id != RTE_MAX_LCORE &&\n+\t\t graph->lcore_id != node->lcore_id && graph->rq != NULL &&\n+\t\t __rte_graph_sched_node_enqueue(node, graph->rq))\n+\t\t\tcontinue;\n+\n+\t\t__rte_node_process(graph, node);\n+\n+\t\thead = likely((int32_t)head > 0) ? head & mask : head;\n+\t}\n+\n+\tgraph->tail = 0;\n+}\n+\n #ifdef __cplusplus\n }\n #endif\n", "prefixes": [ "v3", "11/15" ] }
