bdx_remove(9)

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

okay so welcome to bdx_remove(9), straight out of the Kernel API Manual ✨ pull up a chair, we're talking device removal and it's honestly kinda iconic.

---

🌸 NAME 🌸

bdx_remove — the Device Removal Routine, aka the "bestie, pack it up" function 🧳

---

✨ SYNOPSIS ✨

void bdx_remove (struct pci_dev *pdev );

like, that's the whole signature. no cap. returns void, takes one pointer, done. 💅

---

🦋 ARGUMENTS 🦋

• pdev — the PCI device information struct 🫶 that's the one and only thing you hand over, and it's the device we're saying bye to.

---

💖 DESCRIPTION 💖

so bdx_remove gets called by the PCI subsystem to slide into the driver's DMs and be like "hey bestie, you gotta release this PCI device." 👑 it's a heads-up, not a suggestion.

the way this happens is lowkey two vibes:

• it could be caused by a Hot-Plug event 🔥 (device showing up or dipping out mid-party), or
• it could be because the driver is going to be removed from memory 💀 (like, the whole driver, gone, no more).

either way, bdx_remove is your girl. she gets the memo, you release the device, everyone moves on. periodt. 🌈
