drm_gem_dma...get_sg_table(9)

✨ drm_gem_dma_object_get_sg_table(9) ✨

okay so this is from the Kernel API Manual and it's literally the glow-up guide for one tiny GEM object function, let's get into it 💅

---

🌸 NAME 🌸

drm_gem_dma_object_get_sg_table — the GEM object function for drm_gem_dma_get_sg_table() 🫶

✨ SYNOPSIS ✨

struct sg_table * drm_gem_dma_object_get_sg_table (struct drm_gem_object
*obj );

🎀 ARGUMENTS 🎀

• obj — the GEM object, bestie. that's it, that's the whole vibe.

💖 DESCRIPTION 💖

So what does this little icon actually do? It wraps drm_gem_dma_get_sg_table. 🦋

And here's the main character energy part: drivers that employ the DMA helpers should use it as their drm_gem_object_funcs.get_sg_table handler. Like, that's its whole job in the group chat — no cap.

🌈 RETURN 🌈

It hands you back a pointer to the scatter/gather table of pinned pages 💫 … or NULL on failure 😭 (yes, you have to check. always check.)
