dpu_plane_init_virtual(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dpu_plane_init_virtual — from the Linux Kernel API Manual, section 9, bestie 💅

okay so real talk, this page lives in the Kernel API Manual (that's the 9 section, for the uninitiated — kernel functions, iykyk) and it's all about making a virtual plane ✨

🦋 NAME 🦋

dpu_plane_init_virtual — create new virtualized DPU plane 🎀

like, it literally makes a plane. a virtual one. no cap.

✨ SYNOPSIS ✨

struct drm_plane * dpu_plane_init_virtual (struct drm_device *dev , enum
drm_plane_type type , unsigned long possible_crtcs );

she returns a struct drm_plane *, she takes three things, and yes the line break in the middle is exactly how it's written, don't come for me 🙈

🌸 ARGUMENTS 🌸

  • dev — Pointer to DRM device 🖥️ — like, the whole DRM device this plane belongs to, hi bestie
  • type — Plane type: PRIMARY / OVERLAY / CURSOR 👑 — pick your fighter, these are your three options
  • possible_crtcs — bitmask of crtc that can be attached to the given pipe 🔗 — it's a bitmask, so it's doing bitmask things

💖 DESCRIPTION 💖

Initialize the virtual plane with no backing SSPP / pipe. that's the whole bit — it's virtual, she's got nothing behind her, no SSPP, no pipe, just vibes and a struct drm_plane * 🫶

ngl that's the entire description, short and iconic, so don't go looking for more lore.

and that's the whole page, bestie 🧚 sources say she comes from ./drivers/gpu/drm/msm/disp/dpu1 and she's dated October 2026 — yes, 2026, main character energy, future queen 👑💜 mwah, go init a plane, ily bye 🎀
