pci_match_device(9)

🎀 pci_match_device(9) 🎀

okay so this page is from the Kernel API Manual, and it's all about pci_match_device(9) — literally the “are you my driver's person?” check for PCI devices. bestie, it's giving matchmaking but make it kernel. 💅

✨ NAME ✨

pci_match_device — see if a device matches a driver's list of IDs 💖

🦋 SYNOPSIS 🦋

const struct pci_device_id * pci_match_device (struct pci_driver *drv ,
struct pci_dev *dev , struct pci_device_id *id_copy );

💖 ARGUMENTS 💖

• drv — the PCI driver to match against 🚗
• dev — the PCI device structure to match against 🧸
• id_copy — place to store a copy of pci_device_id for dynamic ID 📝

🌈 DESCRIPTION 🌈

A driver uses this to check whether a PCI device is in its list of supported devices or in the dynids list — which may have been augmented via the sysfs "new_id" file. It returns the matching pci_device_id structure, or NULL if there is no match. no cap: match found = the matching struct; no match = NULL, and that's the whole vibe. 😭
