vmw_du_prim...atomic_check(9)

✨ vmw_du_prim...atomic_check(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil function called vmw_du_primary_plane_atomic_check and honestly? she's the vibe check for your primary plane. let's get into it 🎀

---

🌸 NAME 🌸

vmw_du_primary_plane_atomic_check — literally just checks if the new state is okay, no cap 💅

---

🦋 SYNOPSIS 🦋

int vmw_du_primary_plane_atomic_check (struct drm_plane *plane , struct
       drm_atomic_commit *state );

---

💜 ARGUMENTS 💜

• plane — the display plane, bestie. that's her 🫶
• state — all the info on the new plane state, including the FB 👑

---

🧚 DESCRIPTION 🧚

So what she does is: check if the new state is settable given the current state. iconic behavior, honestly ✨

Other than what the atomic helper checks, she cares about two things:

• the crtc fitting the FB (does it fit? does it slay? 🔥)
• maintaining one active framebuffer (just one, bestie, one 😭)

And then — drumroll 🥁 — Returns 0 on success 💖

and that's the whole page, bestie!! 🥹✨ she lives in ./drivers/gpu/drm/vmwgfx, dated October 2026, and yes the title up top still says vmw_du_prim...atomic_check(9) because that's just her name 😌💖 bye lovie, go check some atomic state 🦋🌸
