drm_crtc_find(9)

💅 drm_crtc_find(9)

Okay so bestie, welcome to the Kernel API Manual ✨ — this one's a tiny little helper that lives in drm_crtc_find(9) and honestly? It's giving "small but iconic." Let's get into it 🎀

---

🌸 NAME 🌸

drm_crtc_find — look up a CRTC object from its ID 🦋

---

⭐ SYNOPSIS ⭐

struct drm_crtc * drm_crtc_find (struct drm_device *dev , struct
drm_file *file_priv , uint32_t id );

Like, that's the whole signature right there 💖

---

✨ ARGUMENTS ✨

• dev — the DRM device, obvi 🖥️
• file_priv — the drm file that we're checking for a lease against 👀
• id — a drm_mode_object ID, iykyk 🔑

💜 DESCRIPTION 💜

So what does it actually do? You can use this to look up a CRTC from its userspace ID 🌈. That's the whole vibe.

But here's the tea ☕ — it's only used by drivers for legacy IOCTLs and interface. No cap. Nowadays, if you're adding extensions to the KMS userspace interface, you should be doing that with drm_property instead. Periodt 💅 That's not me being dramatic, that's literally what it says — legacy stuff stays legacy, new stuff goes through drm_property 🫶

🔥 SEE ALSO 🔥

Go read these next, bestie, they're all in the Kernel file ./include/drm/drm_crtc.h 📚:

• struct drm_crtc_state(9)
• struct drm_crtc_funcs(9)
• struct drm_crtc(9)
• struct drm_mode_set(9)
• drmm_crtc_alloc_with_planes(9)
• drm_crtc_index(9)
• drm_crtc_mask(9)
• drm_for_each_crtc(9)
• drm_for_each_crtc_reverse(9)

---

💀 Quick vibe check before you go: this thing is legacy territory. If you're writing new KMS interface extensions, drm_property is the main character, not this 🧚

Okay that's the whole page, you ate that 🍓💖 Mwah! This cutie came from ./include/drm, dated October 2026 — go forth and look up those CRTCs responsibly, bestie 👑✨
