pci_wait_for_pending(9)

📦 version 7.3.1, in nixpkgs unstable

💖 pci_wait_for_pending(9) 💖

okay bestie, buckle up — this one is a kernel API manual page (the Kernel API Manual one, yes), and it's genuinely so chill. it's one function, it does one little thing, and it does it gorgeously. no cap.

✨ NAME ✨

pci_wait_for_pending — literally just: wait for the @mask bit(s) to clear in the status word at @pos. that's the whole vibe. she waits, she checks, she's done. 🎀

✨ SYNOPSIS ✨

int pci_wait_for_pending (struct pci_dev *dev , int pos , u16 mask );

look at her. three args, one int return, zero drama. 💅

🌸 ARGUMENTS 🌸

  • dev — the PCI device you're operating on. the main character of this whole situation, fr fr. 🫶
  • pos — config space offset of the status word. iykyk — that's where in config space we're peeking. 👀
  • mask — mask of the bit(s) you actually care about in that status word. everything else? not invited to the party. 🙈

🦋 DESCRIPTION 🦋

So here's the tea: this function returns 1 when the mask bit(s) in the status word have cleared, and 0 otherwise. that's it. that's the sentence. iconic behaviour, honestly. ⭐

lowkey the whole function is a vibe check for bits — did they clear or not? 1 = slay, yes. 0 = not yet, bestie. 🔥

👑 SEE ALSO 👑

like… the whole PCI friend group showed up. bestie behaviour honestly. 💜

and that's the page, babes 🧚 — brought to you straight out of ./drivers/pci (the source/version corner of the world), dated October 2026. periodt. 💅✨
