okay so real talk, this one is short but it's important, so pay attention 💖

✨ NAME ✨

drm_gpuvm_resv_object_alloc — literally just allocates a dummy &drm_gem_object, no cap 🫶

🌸 SYNOPSIS 🌸

struct drm_gem_object * drm_gpuvm_resv_object_alloc (struct drm_device *drm );

🦋 ARGUMENTS 🦋

  • drm — the driver's drm_device, that's it, that's the whole arg 👑

💅 DESCRIPTION 💅

So what this does is it allocates a dummy drm_gem_object ✨ and the whole point of this lil guy is that you can pass it to drm_gpuvm_init so it can serve as the root GEM object — like the main character 👑 — providing the drm_resv that's shared across drm_gem_objects local to a single GPUVM. iykyk 💜

🌈 RETURN 🌈

  • on success → you get the drm_gem_object 🎉
  • on failure → NULL 😭 (vibe check failed, handle it)
