radeon_surface_init(9)

✨ radeon_surface_init(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is a little function from the radeon crew — like, a tiny little function, but she still has a job okay 💅

---

🌸 NAME 🌸

radeon_surface_init — clears the GPU surface registers, periodt ✨

---

🎀 SYNOPSIS 🎀

void radeon_surface_init (struct radeon_device *rdev );

---

🦋 ARGUMENTS 🦋

• rdev — a radeon_device pointer 🫶 (yes bestie, that's the whole argument, she's lowkey simple like that)

---

💖 DESCRIPTION 💖

So what she does is: clear the GPU surface registers (for r1xx–r5xx). That's it. That's the whole vibe. No cap, no extra steps, just clearing the surface registers so the GPU starts fresh 🧚
