rdma_create_qp(9)

💅 rdma_create_qp — a Kernel API Manual moment

okay so bestie, welcome to rdma_create_qp(9), a page from the Kernel API Manual, and it is literally three arguments long. we love a low-effort legend. let's get into it 🎀

---

✨ NAME ✨

rdma_create_qp — allocate a QP and associate it with the specified RDMA identifier.

like, you're making a Queue Pair and then introducing it to the RDMA id of your dreams. matchmaking, but for kernel objects 🫶

---

✨ SYNOPSIS ✨

int rdma_create_qp (struct rdma_cm_id *id , struct ib_pd *pd , struct
ib_qp_init_attr *qp_init_attr );

it returns an int, it takes three pointers, and yes there's a space before every comma. they did that. we respect it 🧚

---

✨ ARGUMENTS ✨

okay so brace yourself, the original page is going through something and did NOT write these up. not me exposing the documentation like this, but fr fr:

• id — -- undescribed -- 😭
• pd — -- undescribed -- 💀
• qp_init_attr — -- undescribed -- 🙈

that's it. that's the whole section. i cannot make the manpage say more than it says, so i'm not gonna invent lore about what these do. the page is silent, and we're gonna sit in that silence together. iconic, honestly 👑

---

✨ DESCRIPTION ✨

here's the actual tea, and it's good tea 🍓

QPs allocated to an rdma_cm_id will automatically be transitioned by the CMA through their states.

the way that the CMA just handles the state transitions for you… no manual stepping, no babysitting the QP through every state, it just goes. main character energy 🔥

ngl this is the entire description. short, sweet, and it ate. periodt 💅

---

✨ SEE ALSO ✨

buckle up bestie, this list is LONG and honestly kind of iconic 🦋

this page has a Kernel file reference: ./include/rdma/rdma_cm.h — go read it, it's giving source of truth ✨

and then the whole squad:

• rdma_create_id(9)
• rdma_destroy_id(9)
• rdma_restrict_node_type(9)
• rdma_bind_addr(9)
• rdma_resolve_addr(9)
• rdma_resolve_route(9)
• rdma_resolve_ib_service(9)
• rdma_destroy_qp(9)
• rdma_init_qp_attr(9)
• rdma_listen(9)

• rdma_read_gids(9)

twenty-one cross-references for a page with three undescribed arguments. the confidence? unmatched 👑✨

🌸 cute little sign-off 🌸

this masterpiece came out of ./include/rdma and it's stamped October 2026 — so in the year 2026 someone was still out here shipping -- undescribed -- in a kernel manpage and honestly? we stan a consistent queen 💖

go create a QP bestie, the CMA's got your back 🎀💅
