get_pci_node_path(9)

💅 get_pci_node_path(9) — like, the Kernel API Manual page you actually wanna read 🎀

okay so bestie, this is get_pci_node_path from the Kernel API Manual and honestly? it's a tiny function with main character energy. it takes a PCI device and tells you where it lives on the hardware tree. short, sweet, slay. let's get into it ✨

---

🌸 NAME 🌸

get_pci_node_path — literally determines the hardware path for a PCI device. that's it. that's the whole vibe check 💖

---

✨ SYNOPSIS ✨

void get_pci_node_path (struct pci_dev *pdev , struct hardware_path *path );

no return value, no drama, void and iconic 🫶

---

🎀 ARGUMENTS 🎀

• pdev — the device you want the path for. the main character of this whole operation 👑
• path — a pointer to a previously-allocated array where the path gets dropped. like, you bring the container, the function just fills it. no cap, allocate it first or it's giving undefined chaos 😭

---

🦋 DESCRIPTION 🦋

so what it does is fill in the hardware_path structure with the route to the PCI device you passed in as pdev. that structure is then suitable for passing to PDC calls — that's the whole point, that's the assignment, and it ate 🔥

not me being obsessed with how a function this small is this important, but here we are 💜
