drm_dev_get(9)

💖 drm_dev_get(9) — the Kernel API Manual glow-up 💖

okay so bestie, welcome to the drm_dev_get page — it's from the Linux Kernel API Manual and it's literally about taking a reference on a DRM device 🎀

---

✨ NAME ✨

drm_dev_get — take a reference of a DRM device 🫶

---

🌸 SYNOPSIS 🌸

void drm_dev_get (struct drm_device *dev );

---

🦋 ARGUMENTS 🦋

• dev — the device you wanna take a reference of... or NULL, bestie, no judgment 💅

---

⭐ DESCRIPTION ⭐

So what this does is it bumps the ref-count of dev up by one. That's it. That's the whole vibe. ✨

⚠️ but like, fr fr — you must already own a reference when you call this. not optional. no cap.

When you're done with it, use drm_dev_put to drop this reference again, okay? 🫶

This function never fails. iconic behavior honestly 👑. However — and this is the important part, so listen up — this function does not provide any guarantee whether the device is alive or running 😭. It only provides a reference to the object and the memory associated with it. that's it. that's all it's giving 💀
