drm_gpuvm_is_extobj(9)

💅 drm_gpuvm_is_extobj(9) 💅

okay so bestie, welcome to the Kernel API Manual — today’s main character is drm_gpuvm_is_extobj, and it’s lowkey here to tell you whether the given &drm_gem_object is an external object. no cap. 🫶

🌸 NAME 🌸

drm_gpuvm_is_extobj — indicates whether the given &drm_gem_object is an external object 💖

✨ SYNOPSIS ✨

bool drm_gpuvm_is_extobj (struct drm_gpuvm *gpuvm , struct drm_gem_object *obj );

like, that’s the whole vibe check: hand it a gpuvm and an obj, get a bool back. periodt. ✨

🎀 ARGUMENTS 🎀

• gpuvm — the drm_gpuvm to check 👀
• obj — the drm_gem_object to check 🎀

💖 RETURN 💖

Returns true if the drm_gem_object’s dma_resv differs from the drm_gpuvm’s dma_resv; otherwise it returns false. literally that’s it, bestie — just a resv comparison 💅
