💅 vmw_du_helper_plane_update(9) — from the Kernel API Manual, bestie 🎀

Okay so picture this: you're deep in the kernel, you've got a display unit that needs a plane update, and you're like "who's gonna handle this for me??" Enter vmw_du_helper_plane_update. It's literally the helper that does the plane update on a display unit. Main character energy, no cap. ✨

🌸 NAME 🌸

vmw_du_helper_plane_update — the helper that does the plane update on a display unit. That's it, that's the whole vibe. 🦋

---

⭐ SYNOPSIS ⭐

int vmw_du_helper_plane_update (struct vmw_du_update_plane *update );

---

💖 ARGUMENTS 💖

• update — the closure structure. Yeah, that one. Hand it over, she'll take it from here. 🫶

🧚 DESCRIPTION 🧚

So here's the tea: call this helper after you've set your callbacks in vmw_du_update_plane, and it'll do the plane update on the display unit for you. Setup first, then call — in that order, bestie, it's giving correct usage. 💅

---

👑 RETURN 👑

0 on success, or a negative error code on failure. So basically, if you see 0, slay. Anything negative? That's your sign something went sideways. 😭
