🌸 rte_graph_feature_register 💅

Okay bestie, so this page is literally about rte_graph_feature_register, and it's from the Library Functions Manual section of the DPDK docs — yes, the rte_graph_...e_register(3) one, we're doing it, we're here 🫶

  • rte_node_t feature_node_id
  • rte_node_process_t feature_process_fn

💖 Detailed Description 💖

It's the feature registration structure you hand over to RTE_GRAPH_FEATURE_REGISTER(). That's it, that's the whole vibe.

Fr fr, it lives at Definition at line 237 of file rte_graph_feature_arc.h.

🔥 Member Function Documentation 🔥

⭐ STAILQ_ENTRY (rte_graph_feature_register )

Pointer to the next registered feature in the same arc. Like, "who's next in line, bestie?" energy 🧚

💜 Field Documentation 💜

🌸 const char* arc_name

Name of the arc — and the arc is registered either via RTE_GRAPH_FEATURE_ARC_REGISTER() or via rte_graph_feature_arc_create(). Pick your fighter ✨

Definition at line 247 of file rte_graph_feature_arc.h.

🌈 const char* feature_name

Name of the feature. Literally just the name 🎀

Definition at line 250 of file rte_graph_feature_arc.h.

💫 rte_node_t feature_node_id

Node id of feature_node.

Setting this field can be skipped if you're registering the feature via RTE_GRAPH_FEATURE_REGISTER() — so yeah, optional, you don't have to 👑

Definition at line 258 of file rte_graph_feature_arc.h.

🦋 rte_node_process_t feature_process_fn

The feature node's process() function — it's the one calling the feature fast path APIs. Very main character.

If the application calls rte_graph_feature_arc_init(), then node->process() provided in RTE_NODE_REGISTER() gets overwritten by this function. Not me warning you about the overwrite 😭

Definition at line 267 of file rte_graph_feature_arc.h.

🍓 struct rte_node_register* feature_node

Pointer to the Feature node registration. 🫶

Used when features are registered via RTE_GRAPH_FEATURE_REGISTER().

Definition at line 275 of file rte_graph_feature_arc.h.

⭐ const char* runs_after

Feature ordering constraint runs_after: the name of the feature after which "this feature" should run.

Definition at line 280 of file rte_graph_feature_arc.h.

💅 const char* runs_before

Feature ordering constraint runs_before: the name of the feature which must run after "this feature".

Definition at line 285 of file rte_graph_feature_arc.h.

👑 rte_graph_feature_override_index_cb_t override_index_cb

Lets each feature registration override arc->max_indexes. Highkey powerful.

If it's set, struct rte_graph_feature_arc_register::max_indexes gets calculated like this (and this happens before calling rte_graph_feature_arc_create()):

FOR_EACH_FEATURE_REGISTER(arc, feat) {
rte_graph_feature_arc_register::max_indexes =
max(feat->override_index_cb(),
rte_graph_feature_arc_register::max_indexes) }
Definition at line 298 of file rte_graph_feature_arc.h.

🎀 rte_graph_feature_change_notifier_cb_t notifier_cb

Callback for notifying any change in feature enable/disable state. Basically a little "hey bestie, something changed" ping 💌

Definition at line 303 of file rte_graph_feature_arc.h.
