PCI_DRIVER_..._DEVICE_VFIO(9)

okay bestie, welcome to the PCI_DRIVER_..._DEVICE_VFIO(9) page from the Kernel API Manual 💅✨ — the header keeps it abbreviated, but the actual main character is PCI_DRIVER_OVERRIDE_DEVICE_VFIO. it’s giving tiny macro, big VFIO energy, and we’re getting into every single detail. 🫶

🌸 NAME 🌸

PCI_DRIVER_OVERRIDE_DEVICE_VFIO — a macro used to describe a VFIO "driver_override" PCI device. 💖

---

✨ SYNOPSIS ✨

PCI_DRIVER_OVERRIDE_DEVICE_VFIO (vend , dev );

that’s the whole call, no cap. 🎀

---

🦋 ARGUMENTS 🦋

• vend — the 16 bit PCI Vendor ID 💜
• dev — the 16 bit PCI Device ID 🌈

---

💅 DESCRIPTION 💅

This macro is used to create a struct pci_device_id that matches a specific device. the subvendor and subdevice fields will be set to PCI_ANY_ID, and the driver_override will be set to PCI_ID_F_VFIO_DRIVER_OVERRIDE. that’s the whole magic trick ✨ — specific-device matching with the VFIO override vibe baked in.
