drm_gpuvm_resv_obj(9)

💅 drm_gpuvm_resv_obj — ok bestie listen up

So this is a page from the Kernel API Manual, and it's about drm_gpuvm_resv_obj — the little helper that hands you the &drm_gem_object that's holding onto a &drm_gpuvm's &dma_resv. That's the whole vibe. Short page, iconic energy, let's get into it. ✨

---

🌸 NAME 🌸

drm_gpuvm_resv_obj — returns the &drm_gem_object holding the &drm_gpuvm's &dma_resv

Like, you give it a gpuvm, it gives you back the gem object that's carrying the resv. That's it. That's the function. 🫶

---

✨ SYNOPSIS ✨

drm_gpuvm_resv_obj (gpuvm__ );

That's literally the whole signature, no cap. One argument, one return, zero drama. 💅

---

🎀 ARGUMENTS 🎀

• gpuvm__ — the drm_gpuvm. Yeah, the double underscore is really out here living its truth, and we respect it. This is the gpuvm you're asking about.

---

🌈 RETURN 🌈

A pointer to the drm_gem_object holding the drm_gpuvm's shared dma_resv. 🦋

So like… you get a pointer back. To a gem object. Which is the one holding the shared resv. Simple as that, fr fr.

💀 Real talk moment: this page is deliberately tiny. It's one function, one argument, one return value. But the SEE ALSO section? That's the whole friend group chat. Go read those too, iykyk.
