drm_noop(9)

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

okay so picture this: you're deep in the drm_noop manpage from the Kernel API Manual, and honestly? it's a whole mood. it's short, it's sweet, it does literally nothing, and it slays at it. let's get into it ✨

🌸 NAME 🌸

drm_noop — the DRM no-op ioctl implementation. yes, that's it. that's the whole job. and it ate. 💅

---

🎀 SYNOPSIS 🎀

int drm_noop (struct drm_device *dev , void *data , struct drm_file
*file_priv );

look at that signature, it's giving main character energy fr fr 🫶

---

✨ ARGUMENTS ✨

• dev — the DRM device for the ioctl 🖥️ like, who are we doing this for
• data — the data pointer for the ioctl 📦 the little payload bestie
• file_priv — the DRM file for the ioctl call 📄 the file it's all happening on

---

💖 DESCRIPTION 💖

okay so this is a no-op implementation for drm ioctls, and before you come for it — it's actually useful, no cap. here's the tea 🍵: it's for deprecated functionality where we literally can't return a failure code, because existing userspace checks the result of the ioctl but doesn't actually care about the action. so we give it a 0, it gives us peace, everyone goes home happy. the way that works out is honestly iconic.

lowkey important: the reason it can't fail is about userspace expectations, not because anything unsafe is happening — it's just a polite little no-op sitting there doing nothing on purpose. 🙈

Always returns successfully with 0. that's the whole vibe check and it passes every time 💀✨
