💖 drm_gem_dma_get_sg_table(9) 💖

okay bestie, welcome to the Kernel API Manual page for drm_gem_dma_get_sg_table — yes that's a whole mouthful, we're saying it together, one breath, let's go 🌬️✨

---

🌸 NAME 🌸

drm_gem_dma_get_sg_table — literally here to provide a scatter/gather table of pinned pages for a DMA GEM object. that's the whole job. that's the assignment. she ate and left no crumbs 🍓

---

🦋 SYNOPSIS 🦋

struct sg_table * drm_gem_dma_get_sg_table (struct drm_gem_dma_object
       *dma_obj );

like, read it out loud, it's giving function signature realness 💅

---

🎀 ARGUMENTS 🎀

• dma_obj — a DMA GEM object. that's literally it, that's the whole parameter, no notes 🫶

---

✨ DESCRIPTION ✨

so what she does is: this function exports a scatter/gather table by calling the standard DMA mapping API. no cap, that's the vibe — the actual work is handled by the DMA mapping API, she's just the middlewoman making it happen 😌🔥

---

🌈 RETURN 🌈

she hands you back a pointer to the scatter/gather table of pinned pages. and if things go sideways? NULL on failure. so like… always check, bestie, always check 😭💀
