module_pci_driver(9)

💅 module_pci_driver — the Kernel API Manual tea 🫶

Okay so bestie, welcome to module_pci_driver, one of those tiny little kernel macros that lowkey carries your whole PCI driver setup on its back. It's living over in the Kernel API Manual, and honestly? It's giving "small but mighty." ✨

---

🌸 NAME 🌸

module_pci_driver — the helper macro for registering a PCI driver, periodt 💖

---

🦋 SYNOPSIS 🦋

module_pci_driver (__pci_driver );

That's the whole vibe. One macro, one argument, iconic. 🎀

---

⭐ ARGUMENTS ⭐

• __pci_driver — a pci_driver struct, bestie. That's the one thing you hand over and it handles the rest 🫶

---

💜 DESCRIPTION 💜

So here's the tea ☕ — this is a helper macro for PCI drivers that literally do nothing special in module init/exit. Like, nothing. No extra setup, no little rituals, no secret handshake. And because of that, this macro just… handles it for you. It eliminates a lot of boilerplate, and we love a macro that eats the boring parts. 🔥

⚠️ Important caveat, no cap: each module may only use this macro once, and calling it replaces module_init and module_exit. So don't go doubling up on it — it's a one-and-done situation, main character energy only. 💅
