irdma_modify_qp_roce(9)

💅 irdma_modify_qp_roce(9) — like, the modify-qp request page, bestie

okay so this is a page from the Kernel API Manual, and honestly? it's a short one but it matters. irdma_modify_qp_roce does exactly what it says on the label: it's the modify qp request. that's it, that's the whole NAME section. short, sweet, iconic. 🎀

---

✨ SYNOPSIS ✨

int irdma_modify_qp_roce (struct ib_qp *ibqp , struct ib_qp_attr *attr ,
int attr_mask , struct ib_udata *udata );

it returns an int, it takes four things, and yes bestie the spacing in the original is exactly like that, we respect the original 💖

---

🦋 ARGUMENTS 🦋

four of them, no more no less, let's go:

• ibqp — the qp's pointer, for modify. that's the queue pair you're messing with, your main character 🫶
• attr — access attributes. all the vibes of the modify, carried in a struct.
• attr_mask — state mask. it tells everybody which of those attributes actually count.
• udata — user data. the user-side payload, doing its thing.

that's literally all of them. short king behavior ngl 👑

okay so here's the thing: this function lives in the kernel file at ./drivers/infiniband/hw/irdma/verbs.c, and it has so many neighbors. like an entire group chat of functions. here's the full squad, no cap, every single one:

note the very first one is _irdma_destroy_qp(9) with the little underscore — that's not a typo, that's just how it is, don't come for me 🙈 and yes __irdma_poll_cq(9) has two underscores, we stan a double-underscore moment 💀

also lowkey note that irdma_modify_qp(9) is in there too, right next to irdma_modify_qp_roce(9) — siblings! not the same page though, so don't get it twisted bestie ✨

that's the whole page fr fr — no OPTIONS section, no EXIT STATUS, no BUGS, nothing else hiding in there. go read the neighbors if you want more 🤍

this lil page is from ./drivers/infiniband/hw/irdma, dated October 2026, and it's irdma_modify_qp_roce(9) — mwah, bye bestie, go modify those qps responsibly 🧚‍♀️💜
