vkms_config_...rimary_plane(9)

📦 version 7.3.1, in nixpkgs unstable

💅 vkms_config_crtc_primary_plane(9) — like, the Kernel API Manual page bestie 🎀

okay so this is the vkms_config_...rimary_plane(9) page from the Kernel API Manual, and honestly? it's a lil cutie. tiny function, big "where's my plane" energy. let's get into it ✨

✨ NAME ✨

vkms_config_crtc_primary_plane — returns the primary plane for a CRTC 🖥️💖

🌸 SYNOPSIS 🌸

struct vkms_config_plane * vkms_config_crtc_primary_plane (const struct
vkms_config *config , struct vkms_config_crtc *crtc_cfg );

🦋 ARGUMENTS 🦋

  • config — the configuration that contains the CRTC. that's the container, the vibe-holder, the whole situation 🫶
  • crtc_cfg — -- undescribed -- 😭 yeah. the docs literally just say "undescribed" here. not me exposing upstream like this 💀 it's a struct vkms_config_crtc *, that's all we're given, bestie

💜 DESCRIPTION 💜

so here's the tea: if this function finds multiple primary planes, it hands you back the first one. and like... that's not a slay. in that case, the configuration will be invalid. check vkms_config_is_valid for that. no cap 🔥

⚠️ fr fr if you're getting more than one primary plane back, something's cooked — go validate your config.

👑 RETURN 👑

the primary plane, or NULL if none is assigned yet. that's it. that's the whole return 🫡

🌈 SEE ALSO 🌈

okay this is the long part and we are NOT skipping a single one, iykyk. Kernel file ./drivers/gpu/drm/vkms/vkms_config.h, plus:

like, go read them. all of them. it's giving "study group" 📚✨

and that's the page!! this icon lived in ./drivers/gpu/drm/vkms and dropped way back in October 2026 — main character energy from the kernel docs honestly 💅💖 bye bestie, go find that primary plane 🦋
