irdma_build_mpa_v2(9)

📦 version 7.3.1, in nixpkgs unstable

💅 irdma_build_mpa_v2 — like, the MPA V2 frame builder?? yes bestie

okay so this one's from the Kernel API Manual, section 9 — say hi to irdma_build_mpa_v2(9) 👋 it's giving "small function, big job" energy and honestly? iconic.

✨ NAME ✨

irdma_build_mpa_v2 — build a MPA V2 frame 🎀

That's it. That's the whole job. It builds the frame. She's a builder. Periodt.

💖 SYNOPSIS 💖

void irdma_build_mpa_v2 (struct irdma_cm_node *cm_node , void
*start_addr , u8 mpa_key );

not a single return value in sight — void ate and left no crumbs 💀 she does the thing and dips.

🦋 ARGUMENTS 🦋

three besties walk into a function:

  • cm_node — the connection's node 🫶 like, whose connection? this one's. it's the CM node for the connection you're working on.
  • start_addr — the buffer start address ✨ where the buffer starts. that's the vibe check and it passed.
  • mpa_key — this is the u8 little guy that says whether we're doing read0 or write0 👑 two moods, one key.
ngl there's no return value and no error path listed here — it's literally just "build a MPA V2 frame" and that's the whole assignment. no cap.

🌈 SEE ALSO 🌈

okay this section is long long, like a group chat where everyone keeps adding themselves. the kernel file lives at ./drivers/infiniband/hw/irdma/cm.c and these are all its friends 💜

like, genuinely every single one of them. no skips, no "etc." — we don't do that here 💅

okay so that's the whole page, mwah 💋

cute little sign-off bestie: this one's served from ./drivers/infiniband/hw/irdma 💖 and the version vibe is stamped October 2026 🗓️✨ so like, future girlie energy, obsessed. and yeah — the manual is irdma_build_mpa_v2(9) in case you forgot in the last thirty seconds 🙈 love u, go build some frames 🦋
