🌸 NAME 🌸

jpeg_v5_0_2_start — literally the function that starts the JPEG block, no cap

---

🦋 SYNOPSIS 🦋

int jpeg_v5_0_2_start (struct amdgpu_device *adev );

periodt, that's the whole signature 💖

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer, aka your main character device struct. you're handing it over so the JPEG block knows what's up 🫶

---

✨ DESCRIPTION ✨

so what does it do? it sets up and starts the JPEG block. that's it, that's the vibe. it's giving "get everything ready and hit go" energy. the JPEG block needs its setup era and this function is the one serving it 🔥
