💅 drm_gem_shmem_prime_import_sg_table(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a (9) page, which is kernel-dev territory, so grab a lil snack and let's go 🍓

---

✨ NAME ✨

drm_gem_shmem_prime_import_sg_table — literally the function that produces a shmem GEM object out of another driver's scatter/gather table of pinned pages 🎀

---

🌸 SYNOPSIS 🌸

struct drm_gem_object * drm_gem_shmem_prime_import_sg_table (struct
drm_device *dev , struct dma_buf_attachment *attach , struct sg_table
*sgt );

no cap, that's the whole signature 💖

---

🦋 ARGUMENTS 🦋

• dev — the Device you're importing into, periodt.
• attach — the DMA-BUF attachment, iykyk.
• sgt — the scatter/gather table of pinned pages, the main character of this whole operation 👑

---

🎀 DESCRIPTION 🎀

so this function imports a scatter/gather table that some other driver exported via DMA-BUF. the way it works is: drivers that use the shmem helpers should set this bad boy as their drm_driver.gem_prime_import_sg_table callback. that's it, that's the vibe check ✅

---

⭐ RETURN ⭐

you get back a pointer to a newly created GEM object 💫 — or, if things go sideways, an ERR_PTR-encoded negative error code on failure 😭 (ngl, always check for that one, bestie).
