irdma_create_cq(9)

💅 irdma_create_cq — it's giving "create cq", bestie

okay so first things first: this page is irdma_create_cq from section 9 of the Kernel API Manual, and if you're here you're probably deep in RDMA land at 2am. welcome, i'm obsessed already 🫶

✨ NAME ✨

irdma_create_cq — create cq. that's it. that's the whole name. short, sweet, iconic 👑

---

🌸 SYNOPSIS 🌸

int irdma_create_cq (struct ib_cq *ibcq , const struct ib_cq_init_attr
*attr , struct uverbs_attr_bundle *attrs );

like look at that signature. it returns an int, it takes three pointers, and it's lowkey the main character of this whole page 💅

🦋 ARGUMENTS 🦋

• ibcq — the CQ that got allocated. think of it as the finished product you're handing over, bestie 🎀
• attr — the attributes for that cq. all the personality traits, fr fr ✨
• attrs — the uverbs attribute bundle. the lil group chat of attributes tagging along 🙈

and before the guest list: these all live in the kernel file ./drivers/infiniband/hw/irdma/verbs.c — that's the address, iykyk.

see? told you it was a whole family. and yeah, _irdma_destroy_qp(9) has a leading underscore — that's not a typo, that's just how it is, periodt 💅

that's the whole page, bestie. go forth and create cqs responsibly 🧚

no warnings, no exit statuses, no env vars on this one — it's a short bop, not an album 🎀
