init_qp(9)

💅 init_qp(9) — like, the Queue Pair glow-up page 💅

okay so bestie, welcome to the Kernel API Manual entry for init_qp(9) — yes that's the manual name, it's giving kernel-doc realness and we're obsessed. this one's a little function that sets up a Queue Pair, and honestly? iconic. let's get into it ✨

---

🌸 NAME 🌸

init_qp — Initialize a Queue Pair. that's it. that's the whole vibe. 🎀

---

✨ SYNOPSIS ✨

ok so here's the signature, copy it exactly bestie, no cap, don't be out here "fixing" the spacing:

int init_qp (struct hinic_func_to_io *func_to_io , struct hinic_qp *qp ,
int q_id , struct msix_entry *sq_msix_entry , struct msix_entry
*rq_msix_entry );

look at her. five args. a whole main character. 💅

---

🦋 ARGUMENTS 🦋

every single one of these matters, so let's go down the list, no skipping, we don't do that here 🫶

• func_to_io — the func to io channel that holds the IO components. like, this is the whole closet where all the IO pieces live. you're passing the closet. 🗄️
• qp — pointer to the qp to initialize. this is the Queue Pair we're about to give the glow-up to, and it's a pointer, so be normal about it. 🔥
• q_id — the id of the qp. yup. the number. the identity. every qp needs one. ✨
• sq_msix_entry — msix entry for sq. (sq = the send side of the operation, and it's getting its own msix entry, periodt.) 📨
• rq_msix_entry — msix entry for rq. (rq = the receive side, matching bestie to the one above. they're a set, iykyk.) 📬

ngl the two msix entries are literally a matched pair and i think that's adorable

---

💖 DESCRIPTION 💖

here's the whole deal, and it's short because she's efficient:

• Return 0 — Success 🎉 (slay)
• negative — Failure 😭 (we don't talk about it, but like… handle your return value bestie)

that's genuinely the entire description. no notes. she said what she said. 💀

🔥 SEE ALSO 🔥

if you're done here (you're not, but okay) go read these next, they're all part of the same little friend group 🌈

• Kernel file ./drivers/net/ethernet/huawei/hinic/hinic_hw_io.c — yes, the actual source, go look at her, she's right there 👀
• write_qp_ctxts(9)
• destroy_qp(9)
• hinic_io_create_qps(9)
• hinic_io_destroy_qps(9)
• hinic_io_init(9)
• hinic_io_free(9)

like a whole squad. init, create, destroy, free — the full lifecycle arc, genuinely a coming-of-age story 🧚

---

⭐ reminder bestie: init_qp returns 0 on success and negative on failure. check it. love yourself. 💜

okay and finally the sign-off, because the source of this whole thing is ./drivers/net/ethernet/huawei/... and the date on it is October 2026, so like… mark your calendars, this page is from the future apparently 😭🕰️ anyway mwah, go initialize some queue pairs, you've got this 🎀💖✨
