drm_gem_vra..._create_dumb(9)

💅 drm_gem_vra..._create_dumb(9) 💅

okay so this page lives in the Kernel API Manual, and the filename is literally truncated to drm_gem_vra..._create_dumb(9) — the way the real function name is drm_gem_vram_fill_create_dumb and the header just gave up halfway 😭 iconic behavior honestly. anyway bestie, let's get into it ✨

---

🌸 NAME 🌸

drm_gem_vram_fill_create_dumb — the lil helper that does the boring paperwork for implementing &struct drm_driver.dumb_create 🫶

---

✨ SYNOPSIS ✨

int drm_gem_vram_fill_create_dumb (struct drm_file *file , struct
drm_device *dev , unsigned long pg_align , unsigned long pitch_align ,
struct drm_mode_create_dumb *args );

---

🎀 ARGUMENTS 🎀

• file — the DRM file, that's her 💖
• dev — the DRM device, the whole vibe
• pg_align — the buffer's alignment, measured in multiples of the page size 📏
• pitch_align — the scanline's alignment, in powers of 2 🔢
• args — the arguments exactly as they were handed to struct drm_driver.dumb_create

---

🦋 DESCRIPTION 🦋

so here's the tea ☕: this helper function fills struct drm_mode_create_dumb, which is the struct that struct drm_driver.dumb_create uses. that's the whole job. that's her main character arc.

if you're implementing this interface, the move is: forward your arguments straight to this helper, plus whatever driver-specific parameters you've got on the side. no cap, it's that simple 💅

---

👑 RETURN 👑

0 on success, or a negative error code otherwise. periodt. 💀
