msg_fetch_notification(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 msg_fetch_notification (9) — Kernel API Manual, bestie edition 🌸

Okay so this one's from the Kernel API Manual — yes, the whole manual, and we're about to get into it. Sit down, hydrate, let's go 💅

✨ NAME ✨

msg_fetch_notification — fetch the notification payload out of the transport SDU. That's it, that's the whole job 🎀

✨ SYNOPSIS ✨

void msg_fetch_notification (struct scmi_msg_payld *msg , size_t len ,
size_t max_len , struct scmi_xfer *xfer );

Look at her. <italic>void</italic>, so she's not handing anything back — she just does the thing and dips 🦋

✨ ARGUMENTS ✨

Four of them, no notes, icon behavior:

  • msg — the transport SDU that's carrying the notification 🧚 This is the actual thing with the payload in it.
  • len — the size of the transport SDU. Yes, the length. Yes, you do have to pass it. No, she won't guess 💀
  • max_len — the maximum SCMI payload size to fetch. It's giving "please don't go past this line" 🚧
  • xfer — the notification message itself. This is where the notification lives, lowkey the main character of the whole function 👑

✨ SEE ALSO ✨

The family reunion, all from the kernel file ./drivers/firmware/arm_scmi/msg.c — go say hi to the siblings:

msg_fetch_response(9) is literally her cousin and they're always getting compared. Not fair, but okay 🙈

Ngl, that synopsis formatting with the space before the commas? That's just how it came out of the manpage, bestie. We do not touch the code. Periodt 💖

And that's the whole page! Shoutout to ./drivers/firmware/arm_scmi — that's the source and version vibe — and to October 2026, the date, which is honestly so soon. Slay, see you in the next one 🌈👑
