mpt_attach(9) — Kernel API Manual, but make it iconic ✨

Okay so bestie, let me introduce you to mpt_attach — she's from the Kernel API Manual and she's lowkey one of the most important functions in the MPT adapter universe. Let me break it down for you, no cap. 💅

🎀 NAME 🎀

mpt_attach — installs a PCI intelligent MPT adapter. That's her whole job. That's the assignment and she ate. 👑

✨ SYNOPSIS ✨

int mpt_attach (struct pci_dev *pdev , const struct pci_device_id *id );

Like, she returns an int and takes two args. Very demure, very mindful. 🧚

🦋 ARGUMENTS 🦋

  • pdev — a pointer to the pci_dev structure. That's your PCI device vibes, fr fr.
  • id — the PCI device ID information. It's giving "who am I, really?" energy. 🪪

🔥 DESCRIPTION 🔥

So here's the tea ☕ — this routine does all the steps necessary to bring the IOC of an MPT adapter to a OPERATIONAL state. Like, she wakes the whole thing up and makes it perform. Main character energy, honestly.

That includes:

  • registering memory regions 📝
  • registering the interrupt ⚡
  • allocating request and reply memory pools 🏊‍♀️

She also pre-fetches the LAN MAC address of a Fibre Channel MPT adapter. Not her job technically but she's thoughtful like that. 🫶

Return codes are giving:

  • 0 → success, slay 💖
  • non-zero → failure, not slay 😭
Tiny little TODO bestie: "Add support for polled controllers" — so if you were wondering, no, that's not supported yet. Don't @ me. 🙈

💜 SEE ALSO 💜

Okay this list is long but every single one of these is iconic in her own right, so let me read them all out, periodt:

Like, she knows everyone. The connections are unreal. 💀✨

And that's the whole page bestie — brought to you fresh from ./drivers/message/fusion with the October 2026 date, all wrapped up in the Kernel API Manual aesthetic. Go forth and attach those MPT adapters, you've got this. 🌈🫶💖
