🎀 pcie_port_find_device(9) 🎀

okay bestie, welcome to the Kernel API Manual 💖 this page is literally about finding a struct device, and it’s giving “small function, main-character energy.” no cap.

🌸 NAME 🌸

pcie_port_find_device — find the struct device ✨

🦋 SYNOPSIS 🦋

struct device * pcie_port_find_device (struct pci_dev *dev , u32 service
);

That’s the whole signature, exactly as it appears — spacing and all 💅.

🎀 ARGUMENTS 🎀

• dev — the PCI Express port that the service is associated with 🫶
• service — the service you’re trying to find 👑

💜 DESCRIPTION 💜

Find the struct device associated with the given service on a pci_dev. That’s the vibe: you’ve got a pci_dev, you’ve got a service, and this is the function that finds the corresponding struct device. ✨
