irdma_create_cm_node(9)

🦋 irdma_create_cm_node(9) — the Kernel API Manual, bestie edition 💅

okay so bestie, we're deep in the irdma source tree and you've stumbled onto a page from the Kernel API Manual — irdma_create_cm_node(9) — and I promise it's not as scary as it looks. sit down, hydrate, let's go 🫶

---

✨ NAME ✨

irdma_create_cm_node — make a connection node with params 💖

like, literally, that's the whole job. it builds you a connection node, and it takes params to do it. no cap.

---

✨ SYNOPSIS ✨

int irdma_create_cm_node (struct irdma_cm_core *cm_core , struct
irdma_device *iwdev , struct iw_cm_conn_param *conn_param , struct
irdma_cm_info *cm_info , struct irdma_cm_node **caller_cm_node );

five args, one int return. it's giving "short and iconic". 👑

---

✨ ARGUMENTS ✨

• cm_core — cm's core, fr fr. it's the core of the cm. the main character energy of the whole operation 🎀
• iwdev — the iwarp device structure 🌸. yes, the device one. iykyk.
• conn_param — connection parameters 💫 the actual deets for the connection.
• cm_info — quad info for connection ✨ quad info, specifically. for the connection. obsessed.
• caller_cm_node — pointer to cm_node structure to return 🦋. this is the out-param bestie — it's how the function hands you back your very own cm_node.

---

✨ SEE ALSO ✨

the manpage literally points at a kernel file — ./drivers/infiniband/hw/irdma/cm.c — and then drops the entire friend group at you 😭 so here's every single one, no skips, no cuts, we don't do that here 💀

🎀 the cute little sign-off 🎀

so that's the page! it lives in ./drivers/infiniband/hw/irdma — that's the source/version vibe of this whole thing — and it was dated October 2026, which is genuinely so far ahead of us it's giving time traveler 😭✨

go read irdma_make_cm_node(9) next bestie, it's literally right there in the see-also. slay, periodt, and happy hacking 🌈💖
