✨ drm_debugfs_clients_add(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one is short and sweet and honestly kind of iconic — it's drm_debugfs_clients_add(9), and we're gonna get you obsessed with per-client debugfs directories. no cap.

---

🌸 NAME 🌸

drm_debugfs_clients_add — adds a per client debugfs directory 🎀

---

🦋 SYNOPSIS 🦋

void drm_debugfs_clients_add (struct drm_file *file );

like, that's the whole vibe. one function, one argument, go off 💅

---

⭐ ARGUMENTS ⭐

• file — the drm_file for a client. that's it, that's the argument, she's serving main character energy 🫶

---

🔥 DESCRIPTION 🔥

so what does she actually do? bestie, she creates the debugfs directory for each client ✨. literally every single client gets their own little directory to live in.

and why do we care? because that directory is what's gonna be used to populate driver specific data for each client — iykyk, the drivers need somewhere cute to put their stuff 🌈.

she also adds the process information debugfs file for each client 📁 — which exists purely to tag which client belongs to which process. the way that's literally just a little name tag so you can tell who's who at the party 🎉.

ngl, this is a side-effect-y girlie. you call her, she makes directories and files appear. she's not returning anything — the return type is void, periodt 💀
