drm_mode_cr...tio_property(9)

📦 version 7.3.1, in nixpkgs unstable

💖 drm_mode_create_aspect_ratio_property 💖

Okay bestie, so this is from the Kernel API Manual — like, the actual manual for kernel devs, and we're about to make it make sense. This function is drm_mode_create_aspect_ratio_property, and no cap, it's giving "small but mighty" energy. ✨

🌸 NAME 🌸

drm_mode_create_aspect_ratio_property — create aspect ratio property, periodt. That's literally the whole vibe. 💅

🎀 SYNOPSIS 🎀

int drm_mode_create_aspect_ratio_property (struct drm_device *dev );

Like, you pass it a dev and it hands you back an int. Simple as that, fr fr. 🫶

🦋 ARGUMENTS 🦋

  • dev — DRM device. That's it. That's the whole argument list. Your DRM device, your bestie, the main character of this function call. 💖

✨ DESCRIPTION ✨

So here's the tea: this one gets called by a driver the first time it's needed. Not every time — the first time. And lowkey important: the property it creates must be attached to desired connectors. Like, you can't just make it and leave it sitting there, bestie. It needs a home. 🏠💅

🌈 RETURN 🌈

  • Zero on success — slay, you ate. ✅
  • Negative errno on failure — 😭 not the errno, but okay, at least you know what went wrong.

👑 SEE ALSO 👑

Okay so this list is long — like, genuinely a whole group chat of related functions. But I'm not skipping a single one because every single reference matters. Here we go, bestie:

Like, that's the whole squad right there. 🔥

Okay that's the whole page, bestie. Now go forth and create those aspect ratio properties. You've got this. 💪✨

So yeah — that's it! This little guy lives in ./drivers/gpu/drm, and this version of the manual is dated October 2026. Go off, kernel dev. 🎀👑💖
