drm_for_each_privobj(9)

💖 drm_for_each_privobj(9) — the private object iterator, bestie 💖

Okay so this is a page from the Kernel API Manual, and it's literally about drm_for_each_privobj — the private object iterator. It's short, it's sweet, it's giving "small but mighty," and we're gonna get through it together 🫶

---

✨ NAME ✨

drm_for_each_privobj — the private object iterator, periodt 💅

---

🌸 SYNOPSIS 🌸

drm_for_each_privobj (privobj , dev );

Yep, that's the whole vibe. Two things go in, and the magic happens. Note the spacing, bestie — copy it exactly, no cap 🔥

---

🎀 ARGUMENTS 🎀

• privobj — this is a pointer to the current private object. And here's the cute part: it gets updated after each iteration 🔄 so it's always pointing at whoever's up next. Main character rotation energy, honestly.
• dev — the DRM device we want to get private objects from. Like, the source of truth. The mothership. The place all the private objects live 🏠

---

🦋 DESCRIPTION 🦋

So what does it actually do? It lets you iterate over all private objects attached to dev 💫 That's it. That's the whole thing. You loop, you get every private object, you live your life. Iconic behaviour, honestly, ate and left no crumbs 👑

🧚 sign-off, bestie 🧚

This lil page lives in ./include/drm, and it's dated October 2026 — yes, future vibes, we're ahead of the curve ⭐ and it's the drm_for_each_privobj(9) page, obviously. Slay, go iterate some private objects, and drink some water 💖✨
