irdma_create_cqp(9)

💅 irdma_create_cqp — kernel API manual, but make it make sense

okay so bestie, welcome to the irdma_create_cqp(9) glow-up ✨ this is the kernel API manual page, and we're gonna read it together like it's the group chat 🫶

---

✨ NAME ✨

irdma_create_cqp — create control qp 💖

(no cap, that's the whole vibe: it makes a control qp. "cqp" = control qp. manifesting ✨)

---

🌸 SYNOPSIS 🌸

int irdma_create_cqp (struct irdma_pci_f *rf );

literally one function, one arg, one int return. iconic. 💅

---

🎀 ARGUMENTS 🎀

• rf — the RDMA PCI function 🦋 that's it, that's the whole parameter. it's the thing you're handing over so the cqp can get built.

---

🔥 DESCRIPTION 🔥

so here's the tea ☕: irdma_create_cqp returns 0 if the cqp and all the resources associated with it are successfully created, and otherwise it returns an error 💀

that's the whole contract, bestie. 0 = slay, everything including all its little resource besties made it 🌈. non-zero = something didn't go through, and you get an error back. no in-between, no "it's complicated". periodt. 👑

okay and a lil heads-up bestie: this page lives in ./drivers/infiniband/hw/irdma, so that's where you go digging if you want to see it in the wild 🧚

and that's the whole page, bestie 💜 this one came from the Kernel API Manual, source path ./drivers/infiniband/hw/irdma, dated October 2026, and it's filed under irdma_create_cqp(9) — mwah, go build that cqp, you got this 🍓👑💅
