No cap, that's the whole signature. Short king energy fr fr 👑

• ring — an amdgpu_ring pointer 🌀 like, that's it, that's the whole argument. It's giving "just hand me the ring and I'll handle the rest."

Okay so picture this: it commits the write pointer to the hardware. That's the vibe. That's the whole job. The write pointer gets committed, the hardware knows about it, everybody moves on with their day 💖
