💅 amdgpu_dma_buf_create_obj — a lil guide from the Kernel API Manual 🎀

okay so bestie, we're deep in the kernel graphics girlies territory rn — this is a page from the Kernel API Manual, and it's all about making a brand new buffer object so a DMA-buf can come on in and vibe. no cap, it's short but it matters. 🦋

---

✨ NAME ✨

amdgpu_dma_buf_create_obj — literally the function that creates a BO for DMA-buf import 💫

---

🌸 SYNOPSIS 🌸

struct drm_gem_object * amdgpu_dma_buf_create_obj (struct drm_device
       *dev , struct dma_buf *dma_buf );

so it hands you back a struct drm_gem_object * and it takes two things — dev and dma_buf — full breakdown below, mwah 🫶

---

🎀 ARGUMENTS 🎀

• dev — the DRM device, aka the main character of this whole operation 👑
• dma_buf — the DMA-buf itself, the guest of honor arriving for import 🧚

---

💖 DESCRIPTION 💖

Creates an empty SG BO for DMA-buf import. that's it, that's the whole thing — an SG BO, empty, ready for the import to slide in. iconic, minimalist, ate. ✨

---

🌈 RETURN 🌈

You get back a new GEM BO of the given DRM device — and it's representing the memory described by the given DMA-buf attachment and its scatter/gather table. so basically the whole memory situation gets a fresh lil BO to call home 🏠💜
