ib_modify_device(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ib_modify_device — the Kernel API Manual page, bestie edition

okay so real talk, this one is a Kernel API Manual entry, and honestly? It's short, sweet, and does exactly what it says on the tin. No drama, no plot twists. Let's get into it 🎀

✨ NAME ✨

ib_modify_device — change IB device attributes, periodt. That's the whole vibe. You point it at a device, and it changes stuff. Iconic behaviour, lowkey.

🌸 SYNOPSIS 🌸

int ib_modify_device (struct ib_device *device , int device_modify_mask
, struct ib_device_modify *device_modify );

bestie look at that signature. Three args, one int coming back at you. It's giving "I know exactly what I'm doing" energy 💅

🦋 ARGUMENTS 🦋

  • device — the device you wanna modify. The main character, fr. Everything happens to this one.
  • device_modify_mask — the mask of attributes to change. Think of it as your "which of these things am I touching today" list ✨
  • device_modify — the new attribute values. The actual glow-up content lives here 🫶

🔥 DESCRIPTION 🔥

okay so ib_modify_device changes a device's attributes, and how it knows which attributes to change is literally the whole point: it's specified by the device_modify_mask and the device_modify structure. Mask says what, struct says to what. Match made in heaven, no cap 💖

👑 SEE ALSO 👑

also the kernel file ./drivers/infiniband/core/device.c is in the mix — that's where this lives, iykyk 🧚

and here's the full bestie roster, like the whole group chat, every single one:

ngl that's a LOT of cross-references, but every one of them is a real one — go read them, they're all slaying in their own way 💀

and that's the page!! sourced straight from ./drivers/infiniband/core, dated October 2026, and it's ib_modify_device(9) forever and always 🌈⭐ bye bestie, go modify some devices responsibly 💜
