💅 pciehp_unconfigure_device(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a pciehp_unconfigure_device(9) situation and it's lowkey iconic for hotplug girlies ✨

---

✨ NAME ✨

pciehp_unconfigure_device — remove PCI devices below a hotplug bridge 🫶

---

🌸 SYNOPSIS 🌸

void pciehp_unconfigure_device (struct controller *ctrl , bool presence );

---

🎀 ARGUMENTS 🎀

• ctrl — the PCIe hotplug controller, aka the main character running the whole slot situation 👑
• presence — whether the card is still chillin' in the slot. Set it to true for safe removal via sysfs or an Attention Button press, and false for surprise removal 💀

---

🦋 DESCRIPTION 🦋

So what does it actually do? It unbinds PCI devices below a hotplug bridge from their drivers and removes them from the system, periodt ✨

Devices that got safely removed are quiesced 🌸 — all calm, all collected, no drama.

Devices that got surprise removed are marked as such, specifically to prevent further accesses. Not me making sure nobody touches a card that already ghosted the slot 🙈

💡 friendly reminder: presence is not a vibe-check variable, it's real. true = safe removal, false = surprise removal. Choose wisely, bestie 💅
