drm_gem_object_get(9)

💖 drm_gem_object_get(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ today's main character is drm_gem_object_get(9) and honestly she's a tiny little function with one job and she does it flawlessly 🎀

---

✨ NAME ✨

drm_gem_object_get — acquire a GEM buffer object reference 🫶

---

🌸 SYNOPSIS 🌸

void drm_gem_object_get (struct drm_gem_object *obj );

that's it. that's the whole vibe check. void in, void out, reference acquired 💅

---

🦋 ARGUMENTS 🦋

• obj — the GEM buffer object, aka the little guy you're about to hold onto for dear life 🥺

---

⭐ DESCRIPTION ⭐

okay so here's the tea ☕ — this function acquires an additional reference to obj. one more ref, bestie. you're now officially holding a stake in it ✨

but like… it is illegal to call this without already holding a reference 💀 no cap, that's not a vibe, that's a bug. you gotta already have one in your hand before you go grabbing more.

the good news?? No locks required. 🔓 literally none. zero. go off, no mutex needed, it's giving effortless 🌈
