irdma_post_send(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 irdma_post_send — the manual, but make it make sense 🌸

okay so bestie, we're in the Kernel API Manual today 💅 and this page is all about irdma_post_send(9) — one little function that's about to be your whole personality. no cap, it's giving "tiny signature, big responsibilities". let's get into it 🔥

✨ NAME ✨

irdma_post_send — kernel application wr

that's it. that's the whole name section. short and iconic 🎀

🦋 SYNOPSIS 🦋

here's the signature, copied exactly because we do not play with prototypes in this house:

int irdma_post_send (struct ib_qp *ibqp , const struct ib_send_wr *ib_wr
, const struct ib_send_wr **bad_wr );

yes the comma is on the next line. no we're not fixing it. it's in its era 🌈

💖 ARGUMENTS 💖

three args, three vibe checks, let's go:

  • ibqp — qp ptr for wr 🫶 (that's the qp pointer your work request is riding with)
  • ib_wr — work request ptr ✨ (the actual work request pointer, the star of the show)
  • bad_wr — return of bad wr if err 😭 (if something goes wrong, the bad work request gets handed back to you through this)
literally three params and each one has a job. respect the trio 👑

👑 SEE ALSO 👑

first off, the source of truth lives right here — kernel file ./drivers/infiniband/hw/irdma/verbs.c 🌸 so if you want the real real, that's the address.

and then… okay bestie, brace yourself, because this list is long long. iykyk. every single one, in order, no skipping, because i would never do you like that 💜

like… that's the whole extended friend group and you're gonna meet all of them eventually 🧚💫

🎀 the cute sign-off 🎀

this little love letter lives over in ./drivers/infiniband/hw/irdma, and it's stamped October 2026 ⭐ — so go forth, post that send, and may your bad_wr always be NULL 🍓💖 periodt.
