drm_gem_obje...sts_unlocked(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

drm_gem_object_handle_get_if_exists_unlocked — bestie, this grabs you a reference on a user-space handle if there even is one 🫶

okay so real talk, this is a kernel API page (Kernel API Manual), and we're talking about the drm_gem_object_handle_get_if_exists_unlocked(9) function. yes the name is a mouthful. no we are not changing it. periodt.

✨ SYNOPSIS ✨

bool drm_gem_object_handle_get_if_exists_unlocked (struct drm_gem_object
*obj );

🎀 ARGUMENTS 🎀

  • obj — the GEM object, your main character for this whole function 🦋

🌸 DESCRIPTION 🌸

So here's the vibe: this function acquires a reference on the GEM buffer object's handle. That reference is literally required to keep the GEM object alive — no reference, no object, that's just how it is ngl 💀

When you're done with it, you call drm_gem_object_handle_put_if_exists_unlocked to release the reference. don't ghost it, actually put it back 😭

And here's the cute part: if the buffer object has no handle, this function does nothing. no drama, no error, just vibes 🌈

⭐ RETURN ⭐

  • True if a handle exists 👑
  • false otherwise 🙈

and that's the whole page, bestie 🌈✨

cute lil sign-off time 🎀 this one came from ./drivers/gpu/drm, dated October 2026, and yes it's still drm_gem_obje...sts_unlocked(9) in the corner because the name got truncated and we're keeping it 💅 slay.
