mpi3mr_issue_iocfacts(9)

📦 version 7.3.1, in nixpkgs unstable

💅 mpi3mr_issue_iocfacts — the mpi3mr_issue_iocfacts(9) glow-up ✨

okay so real talk, this is a kernel API manual page (section 9, kernel dev vibes only, not for your regular terminal usage 🫶) and it's literally just one function doing one iconic little job. let's get into it 💖

🌸 NAME 🌸

mpi3mr_issue_iocfacts — bestie, it Sends IOC Facts. that's the whole thing. that's the assignment 👑

✨ SYNOPSIS ✨

int mpi3mr_issue_iocfacts (struct mpi3mr_ioc *mrioc , struct
mpi3_ioc_facts_data *facts_data );

two args, one int coming back at you. no cap, that's it 💅

🎀 ARGUMENTS 🎀

  • mrioc — the Adapter instance reference. it's your lil handle to the adapter you're talking to, main character energy 🦋
  • facts_data — the Cached IOC facts data. the facts, already cached, ready to go. iykyk 📦

🧚 DESCRIPTION 🧚

so what does it do? it issues the IOC Facts MPI request through the admin queue, and then it waits for that request to complete — or for it to time out. that's the vibe check: send it, then sit there patiently like a good little driver until something comes back or the clock runs out ⏳💀

lowkey important: there is a timeout. if the completion never shows up, you're not waiting forever, bestie — that's the whole point of the timeout 🌈

🔥 RETURN 🔥

  • 0 on success 🎉 slay
  • non-zero on failures 😭 (that's your sign something went sideways)

👑 SEE ALSO 👑

the friend group is LARGE and honestly kind of iconic. kernel file ./drivers/scsi/mpi3mr/mpi3mr_fw.c is where all these live, and here's every single one, no skipping, we don't do that here 💖:

and that's the whole page, bestie 🫶 go read some source and hydrate 💧

lil sign-off before you go: this whole thing lives in ./drivers/scsi/mpi3mr, it's dated October 2026, and it's page mpi3mr_issue_iocfacts(9) — i.e. a Kernel API Manual entry, so don't be surprised when it doesn't show up in your normal man energy. mwah 💋🎀
