🌸 vfio_ap_mdev_on_cfg_remove(9) 🌸

Hey bestie, welcome to the Kernel API Manual 💖 — this is the page for vfio_ap_mdev_on_cfg_remove, and honestly? It's giving cleanup era. Pull up a chair, grab your iced coffee 🍓, and let's get into it.

✨ NAME ✨

vfio_ap_mdev_on_cfg_remove — the function that responds to the removal of adapters, domains and control domains from the host AP configuration, by unplugging them from the guests that are using them 💅

Like, host config said "these are gone now" and this function is the one who actually goes and tells the guests, okay? No cap, that's the whole vibe.

---

🦋 SYNOPSIS 🦋

void vfio_ap_mdev_on_cfg_remove (struct ap_config_info *cur_config_info
, struct ap_config_info *prev_config_info );

Yup, that's it — void return, two pointers, zero drama ✨

---

🎀 ARGUMENTS 🎀

• cur_config_info — the current host AP configuration information. This is the now snapshot, the main character of the present moment 👑
• prev_config_info — the previous host AP configuration information. This is the before snapshot, the throwback pic you compare against 🙈

So yeah, it's a before/after situation — you hand it both configs and it does the unplugging thing 💀✨
