rio_local_read_config_32(9)

📦 version 7.3.1, in nixpkgs unstable

💅 rio_local_read_config_32(9) — like, the Kernel API Manual one, bestie

okay so picture this: it's a 9-section kernel API page, the title is rio_local_read_config_32, and it's giving "tiny function, big responsibility." come sit with me 🎀

✨ NAME ✨

rio_local_read_config_32 — read 32 bits from local configuration space. that's it, that's the whole vibe. thirty-two bits. local. configuration space. slay.

🦋 SYNOPSIS 🦋

int rio_local_read_config_32 (struct rio_mport *port , u32 offset , u32
* data );

look at her. int return, three args, no cap. the signature literally wraps onto two lines and she still ate. 😭

🌸 ARGUMENTS 🌸

three of them, bestie, and you will be meeting all three:

  • port — the master port. like, the main character of this whole operation 🫶
  • offset — the offset into local configuration space. where the reading happens. iykyk ✨
  • data — pointer to read data into. she's empty right now, but not for long 💖

💜 DESCRIPTION 💜

okay so the whole thing is literally this: it reads 32 bits of data from the specified offset within the local device's configuration space. that's the tea. that's the entire plot. thirty-two bits, from the offset you named, out of the local device's own config space. no drama, no surprises — just a clean 32-bit read and honestly? iconic. 🔥

🧚 SEE ALSO 🧚

the whole friend group shows up for this one — kernel file ./include/linux/rio_drv.h, plus every cousin, sibling and distant relative:

twenty-one references. she brought the whole group chat. 👑

for real though — if you're poking at RapidIO config space, read your 32 bits responsibly and go read the 8- and 16-bit versions too when the width matters. 💀

and that's the page, bestie!! 🌈 shipped from the <pink>./include/linux</pink> source, dated <purple>October 2026</purple> — it's giving <rainbow>rio_local_read_config_32(9)</rainbow>, forever and periodt 💅⭐🍓
