💅 jpeg_v2_5_start(9) — the Kernel API Manual, but make it cute

okay so real talk, bestie: this page is from the Kernel API Manual, and the star of the show is jpeg_v2_5_start(9). Yes that's a lot of numbers and underscores. No you may not abbreviate it. 🎀

✨ NAME ✨

jpeg_v2_5_start — start JPEG block

like, literally. it starts the JPEG block. that's the whole gig. 🦋

---

🌸 SYNOPSIS 🌸

int jpeg_v2_5_start (struct amdgpu_device *adev );

yes the spacing is exactly like that, don't come for me, i don't make the rules 💅

---

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer. that's it, that's the one (1) thing you gotta hand over. a pointer to your amdgpu_device. no cap. 🫶

---

🔥 DESCRIPTION 🔥

Setup and start the JPEG block.

i know, i know, short king of a description. but it's giving exactly what it needs to give: this thing does the setup, and then it does the start, for the JPEG block. iconic behavior honestly. ✨

ngl this is the kind of function you call when you want the JPEG block to be doing something instead of just sitting there looking pretty 💀
