💅 jpeg_v5_0_0_start(9) — the kernel API manual, but make it make sense

okay so bestie, welcome to the jpeg_v5_0_0_start(9) page 💖 this is the one that kicks the whole JPEG block into gear. it's a kernel API manual, it's giving "amd gpu driver internals," and honestly? iconic.

✨ NAME ✨

jpeg_v5_0_0_start — start the JPEG block. that's it. that's the whole vibe. it starts it. 🎀

---

🌸 SYNOPSIS 🌸

int jpeg_v5_0_0_start (struct amdgpu_device *adev);

so it returns an int (as functions do, main character energy) and it takes exactly one (1) argument, no cap.

---

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer. literally just a pointer to the amdgpu device. that's the whole thing. 🫶

---

⭐ DESCRIPTION ⭐

okay so here's the tea: this function sets up and starts the JPEG block. that's genuinely everything this page says. no lore, no side quests, just setup plus start. slay. 💅
