irdma_setup_umode_qp(9)

✨ irdma_setup_umode_qp ✨ <small>(section 9, Kernel API Manual)</small>

okay so bestie, this is the kernel API page for irdma_setup_umode_qp — it lives in the Kernel API Manual, section 9, and it's all about one little job: setting up the sq and rq size in a user mode qp. that's it, that's the whole vibe 🫶

---

🌸 NAME 🌸

irdma_setup_umode_qp — setup sq and rq size in user mode qp ✨

---

💅 SYNOPSIS 💅

int irdma_setup_umode_qp (struct irdma_ucontext *ucontext , struct
irdma_create_qp_req *req , struct irdma_device *iwdev , struct irdma_qp
*iwqp , struct irdma_qp_init_info *info , struct ib_qp_init_attr
*init_attr );

like, six arguments, one int back. she's thorough, she's iconic, no cap 💖

---

🎀 ARGUMENTS 🎀

• ucontext — user context 💫
• req — user request pointer (the actual ask, incoming) 🦋
• iwdev — iwarp device 🌈
• iwqp — qp ptr (user or kernel, she's flexible like that) ⭐
• info — initialize info to return, so you get something back out of this 🌸
• init_attr — Initial QP create attributes 🔥

ngl, everything here is a pointer except the return value, so mind your lifetimes bestie 😭

that's the whole page bestie, you ate that read 💅✨

sign-off time: this one comes from source ./drivers/infiniband/hw/irdma, version dated October 2026, and the page itself is irdma_setup_umode_qp(9). go forth and configure your qp sizes responsibly, mwah 🎀💖🌸
