pci_hp_remove_devices(9)

💅 pci_hp_remove_devices(9) — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual today and this one is literally about yeeting every PCI device under a bus. no cap. it's giving cleanup era. 🧹✨

✨ NAME ✨

pci_hp_remove_devices — remove all devices under this bus

like, all of them. every single one. periodt. 💅

---

🎀 SYNOPSIS 🎀

void pci_hp_remove_devices (struct pci_bus *bus );

note the void — this function returns nothing, it just does the thing and leaves. main character energy, honestly. 🫶

---

🌸 ARGUMENTS 🌸

• bus — the indicated PCI bus 💖

that's it. that's the whole argument list. one (1) bus. she's lowkey simple like that.

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function removes all of the PCI devices under this bus — and not just from one place, bestie, from both:

1. the linux pci device tree 🌈
2. the powerpc EEH address cache 🔥

two whole places. she's thorough. not me being obsessed with a cleanup function but here we are. 💀

⭐ SEE ALSO ⭐

• Kernel file ./arch/powerpc/kernel/pci-hotplug.c — that's where she lives, iykyk 📁
• pcibios_release_device(9) 🫶
• pci_hp_add_devices(9) — yes, the add counterpart, they're a matching set fr fr 👑

---

💜 reminder bestie: this is the remove one. if you were looking for the add one, that's pci_hp_add_devices(9) up there in SEE ALSO. don't mix them up, bestie, i'm begging 🙈

and that's the page!! 🎀 this icon was brought to you by the fine folks at ./arch/powerpc/kernel, dated October 2026, and yes the header said pci_hp_remove_devices(9) three times because manpages love a triple threat. slay. 💅✨🌸
