int jpeg_v4_0_3_start (struct amdgpu_device *adev );

that's it. one function, one arg, returns an int. iconic behavior tbh 🎀

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer. that's the whole vibe. it's giving "just hand me the device and I'll handle it" 🫶

💖 DESCRIPTION 💖

She sets up the JPEG block and then starts it. Setup and start. both. the way she multitasks?? obsessed 😭✨

literally that's the entire job — jpeg_v4_0_3_start is the main character of getting the JPEG block going, and honestly? she ate 🔥
