✨ jpeg_v1_0_start(9) ✨

okay so this is a page from the Kernel API Manual, section 9, and it's literally all about jpeg_v1_0_start — the function that gets your JPEG block up and running. bestie, it's a whole vibe 💅

---

🎀 NAME 🎀

jpeg_v1_0_start — start JPEG block. that's it, that's the whole name, and honestly? iconic. short, sweet, does exactly what it says on the tin 🫶

---

🌸 SYNOPSIS 🌸

void jpeg_v1_0_start (struct amdgpu_device *adev , int mode );

no return value, no drama — it's void, she just does her thing and dips ✨ (and yes, the spacing in there is exactly how the manpage has it, don't come for me 🙈)

---

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer, i.e. the amdgpu device you're working with. that's your main character right there 👑
• mode — the mode, which is either SPG or DPG. pick one, bestie, those are the options 🎀

---

💖 DESCRIPTION 💖

Setup and start the JPEG block. literally that's the assignment: you set it up, then you start it. no cap, no hidden lore, no extra side quests — setup + start, and she's off 🔥
