vmw_du_plane_cleanup_fb(9)

✨ vmw_du_plane_cleanup_fb — Unpins the plane surface 💅

okay so bestie, this is a page from the Kernel API Manual (section 9, the kernel-API girlies 🧚) and it's all about vmw_du_plane_cleanup_fb. Buckle up, it's short but she ate. 🎀

---

🌸 SYNOPSIS 🌸

void vmw_du_plane_cleanup_fb (struct drm_plane *plane , struct
drm_plane_state *old_state );

like, literally just two args and she's done. no return value, no drama. periodt. 💖

---

🦋 ARGUMENTS 🦋

• plane — the display plane herself. main character. 👑
• old_state — this one holds the FB that needs to get cleaned up. she's carrying the framebuffer we're about to unpin. 🙈

---

💜 DESCRIPTION 💜

so what does she actually do? she unpins the framebuffer surface. that's it. that's the whole vibe. 🫶

ngl there's a cute little line down here that says "Returns 0 on success" — which is lowkey funny because the function is void, but hey, we don't gatekeep documentation. 😭✨

bestie note: don't go looking for a return value at the call site, the signature says void and we respect her. 💀

and that's the whole page, bestie! 🍓

cute little sign-off: this one lives in ./drivers/gpu/drm/vmwgfx from the Kernel API Manual, dated October 2026, and she's filed under vmw_du_plane_cleanup_fb(9). slay, go unpin some framebuffers. 💖✨🎀
