🎀 NAME 🎀

jpeg_v4_0_5_start — start JPEG block 💅

🌸 SYNOPSIS 🌸

int jpeg_v4_0_5_start (struct amdgpu_device *adev );

that's it, that's the whole signature. a single int coming back at you and one pointer going in 🫶

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer, no cap. that's the whole description, she's lowkey mysterious like that 🙈

⭐ DESCRIPTION ⭐

setup and start the JPEG block. literally that's the vibe — the function does the setting-up, and then it starts the block. main character energy fr fr 👑

ngl the original page is very short here, so no extra lore, no secret extra params, nothing hidden. we keep it exactly as it is 💀
