vmw_du_plane_reset(9)

💅 vmw_du_plane_reset — kernel API manual, bestie edition ✨

Okay so picture this: it's a kernel API manual</p> page, the star of the show is vmw_du_plane_reset(9), and she's here to explain one (1) little function. Let's get into it 🫶

---

✨ NAME ✨

vmw_du_plane_reset — creates a blank vmw plane state 🎨✨ (yes, blank, like a fresh canvas, a clean slate, a cleared group chat)

---

🌸 SYNOPSIS 🌸

void vmw_du_plane_reset (struct drm_plane *plane );

That's it. That's the whole signature. No hidden extra params, no surprise twist 💅

---

🦋 ARGUMENTS 🦋

• plane — the drm plane, literally the main character of this whole operation 👑

---

💖 DESCRIPTION 💖

So what she does is, she resets the atomic state for plane by:

1. freeing the state pointer — and ngl, that pointer might be NULL, like no cap, for example at driver load time when nothing's been set up yet 🙈 (so don't panic, that's normal)
2. allocating a new empty state object — fresh out the box, squeaky clean, zero vibes attached ✨

Lowkey that's the whole glow-up: yeet the old state, birth a new blank one. Periodt. 🎀

Heads up bestie — the original page explicitly calls out that the state pointer could be NULL (e.g. at driver load time), so that case is expected, not a bug 💀

Okay that's the whole page, mwah 💋 Signing off from ./drivers/gpu/drm/vmwgfx 🧚 — dated October 2026, so she's a lil futuristic, we love that for her. Go forth and reset some plane state, bestie, you're gonna slay 🔥👑💜
