pci_unregister_driver(9)

💖 pci_unregister_driver(9) — Kernel API Manual edition 💖

okay bestie, welcome to the pci_unregister_driver(9) page from the Kernel API Manual. this is the one about politely yeeting a PCI driver out of the kernel’s registry, and yes, it’s giving cleanup-era main character energy. periodt. 💅

---

🌸 NAME 🌸

pci_unregister_driver — unregister a pci driver

---

✨ SYNOPSIS ✨

void pci_unregister_driver (struct pci_driver *drv );

---

🎀 ARGUMENTS 🎀

• drv — the driver structure to unregister. that’s the whole argument, bestie, no cap. 🫶

---

🦋 DESCRIPTION 🦋

okay so here’s the tea: this function deletes the driver structure from the list of registered PCI drivers. then it gives it a chance to clean up by calling its remove function for each device it was responsible for. and finally it marks those devices as driverless. iconic behavior, honestly. 💖
