aperture_re..._pci_devices(9)

✨ aperture_remove_conflicting_pci_devices ✨

okay so bestie, welcome to the Kernel API Manual entry for aperture_remove_conflicting_pci_devices(9) — yes that's the full name, yes it's a mouthful, no we're not shortening it, it's iconic 💅

---

🌸 NAME 🌸

aperture_remove_conflicting_pci_devices — the function that goes and evicts whatever framebuffers are already squatting on your PCI devices 🫶

---

⭐ SYNOPSIS ⭐

int aperture_remove_conflicting_pci_devices (struct pci_dev *pdev ,
       const char *name );

---

🎀 ARGUMENTS 🎀

• pdev — the PCI device in question, the main character of this whole operation 💖
• name — a descriptive name of the requesting driver (basically, who's asking, so everyone knows who did it 👀)

---

🦋 DESCRIPTION 🦋

So here's the vibe: this function removes devices that own apertures within any of pdev's memory bars. Like, all of them, whoever's hanging out in there, they've gotta go ✨

And lowkey the spicy part: the function assumes that a PCI device with shadowed ROM drives a primary display — and because of that assumption it kicks out vga16fb as well. Not asking, just removing 💀

---

🔥 RETURN 🔥

0 on success, or a negative errno code otherwise. That's it, that's the whole return situation 😌
