irdma_sc_manage_ws_node(9)

💅 NAME 💅

okay so bestie, welcome to irdma_sc_manage_ws_node(9) — that's the page, that's the name, and we're deep in the Kernel API Manual, section 9, where the kernel girlies live. ✨

This one is literally irdma_sc_manage_ws_node — it's the function that does the create/modify/destroy thing for a WS node. Three moods, one call. Slay. 💖

---

✨ SYNOPSIS ✨

int irdma_sc_manage_ws_node (struct irdma_sc_cqp *cqp , struct
irdma_ws_node_info *info , enum irdma_ws_node_op node_op , u64 scratch
);

no cap, that's the whole signature — int coming back at you, four arguments going in. 🫶

---

🎀 ARGUMENTS 🎀

okay so here's the cast, and every single one of them matters:

• cqp — the struct for cqp hw. that's the hardware-side situation, she's holding it down. 💅
• info — the node info structure. this is where the actual node tea lives. 🍓
• node_op — the operation selector, and the numbers are very specific: 0 for add, 1 for modify, 2 for delete. not me memorizing these, but also yes, memorize these. 😭
• scratch — a u64 saved to be used during cqp completion. she just sits there being saved until completion time, main character energy honestly. ⭐
