💅 pci_reenable_device(9) — Kernel API Manual, bestie edition 🎀

okay so welcome to the Kernel API Manual (yes that's the manual name, we're fancy now ✨) and today's main character is pci_reenable_device. Buckle up, it's short but it's important.

✨ NAME ✨

pci_reenable_device — resume an abandoned device 🫶

Like, the device got left on read and we're bringing it back to the chat. No cap.

🦋 SYNOPSIS 🦋

int pci_reenable_device (struct pci_dev *dev );

🌸 ARGUMENTS 🌸

  • dev — the PCI device that's getting resumed, i.e. the one we're reviving. This is the device, the whole point of the function, don't lose it 💖

💀 NOTE 💀

okay bestie, listen carefully because this one matters:

This function is a backend of pci_default_resume and is not supposed to be called by normal code. Write a proper resume handler and use that instead. Periodt. 🙈

(translation: it's giving "internal-use-only, don't touch" energy. the function is iconic but it is not for you and me. 😭)

⭐ SEE ALSO ⭐

The kernel file ./drivers/pci/pci.c, plus literally the entire friend group of PCI functions. Yes, all of them. I said what I said. 👑

and that's the whole page, bestie 💜 this gem lives in ./drivers/pci, dated October 2026, and it's filed under pci_reenable_device(9) — go forth, don't call it from normal code, and slay ✨🎀🦋
