drm_gem_shm...mport_no_map(9)

💅 drm_gem_shm...mport_no_map(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual page for drm_gem_shm...mport_no_map(9), and trust me when I say this one is lowkey iconic if you're the kind of driver that likes to keep things unmapped. let's get into it 🎀

---

✨ NAME ✨

drm_gem_shmem_prime_import_no_map — import a dmabuf without mapping its sg_table. that's literally the whole personality. no mapping. none. zero. 🦋

---

🌸 SYNOPSIS 🌸

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

like yes she returns a struct drm_gem_object * and yes she takes exactly two args. periodt. ✨

---

🫶 ARGUMENTS 🫶

• dev — the device you're importing into. home base. the main character device, if you will 💜
• dma_buf — the dma-buf object being imported. hi bestie, come on in 🎀

---

💖 DESCRIPTION 💖

so here's the vibe: some drivers use the shmem helpers but also wanna import a dmabuf without mapping its sg_table. for those drivers, this function is the moment — you can use it as your drm_driver.gem_prime_import implementation. that's it, that's the whole job, and she does it flawlessly. slay. 💅
