ipr_build_ioadl64(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ipr_build_ioadl64 — bestie edition

okay so this is the ipr_build_ioadl64(9) page from the Kernel API Manual, and yes we're going to read the whole thing together. grab a snack. 🍓

✨ NAME ✨

ipr_build_ioadl64 — it builds a scatter/gather list and maps the buffer. that's the whole vibe. that's what it does. 💖

🦋 SYNOPSIS 🦋

int ipr_build_ioadl64 (struct ipr_ioa_cfg *ioa_cfg , struct ipr_cmnd
*ipr_cmd );

like, it hands you back an int. that's the tea. ☕

🎀 ARGUMENTS 🎀

  • ioa_cfg — the ioa config struct. she's the config, she's the blueprint, she's giving main character paperwork. 👑
  • ipr_cmd — the ipr command struct. this one's the actual command doing the doing. 🫶

🌸 DESCRIPTION 🌸

so what's the return value, i hear you ask? bestie it's a whole two-outcome situation:

  • 0 means success — slay, it worked, we love to see it. ✨
  • -1 means failure — not slay, something went sideways, we simply do not stan. 😭

that's it. that's the description. she's concise. she's iconic. periodt. 💅

lowkey the whole point is: build the scatter/gather list, map the buffer, report back whether it ate or flopped. ngl the two outcomes are the entire personality here.

🔥 SEE ALSO 🔥

okay this part is genuinely a lot, so buckle up. the kernel file lives at ./drivers/scsi/ipr.c and here's every single friend in the group chat, no cap — not a single one skipped, i checked, twice:

see? everybody accounted for. iykyk. 🧚

💀 fr fr though — go read the actual page, because these are the facts and the facts are sacred. i'm just here to make them cute.

okay bye bestie, go build that scatter/gather list 💜

and that's the whole thing! this page lives over in ./drivers/scsi, and the version fairy stamped it October 2026 — so if you're reading it later than that, congrats, you're in the future, we love a time traveler. 🦋⭐💖
