✨ sdma_v6_0_start(9) ✨

okay bestie, this is a page from the Kernel API Manual and honestly? it's a whole vibe. it's giving "let's wake up the async dma engines" energy and i am obsessed. 🦋

🌸 NAME 🌸

sdma_v6_0_start — the girlboss that sets up and starts the async dma engines. no cap, that's literally her whole job. 💅

---

⭐ SYNOPSIS ⭐

int sdma_v6_0_start (struct amdgpu_device *adev );

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. that's it. that's the whole argument. she doesn't need much, she's low maintenance. 🫶

---

💖 DESCRIPTION 💖

so what does she do? she sets up the DMA engines and then enables them. that's the entire plot. 🎬

she returns 0 for success — slay — and an error for failure, which is the opposite of slay but we respect the honesty. 😭
