💅 jpeg_v4_0_hw_fini — like, the kernel API manual bestie ✨

okay so real talk, this is a page from the Kernel API Manual (jpeg_v4_0_hw_fini(9)) and it's about shutting a hardware block all the way down. short page, elite energy. let's get into it 🎀

✨ NAME ✨

jpeg_v4_0_hw_fini — stop the hardware block 🛑

like literally, that's the whole job. it stops the hardware block. no cap.

🌸 SYNOPSIS 🌸

int jpeg_v4_0_hw_fini (struct amdgpu_ip_block *ip_block );

returns an int, takes exactly one argument, and yes bestie it's giving very "one job, done well" 💅

🦋 ARGUMENTS 🦋

  • ip_block — Pointer to the amdgpu_ip_block for this hw instance. that's your ticket to the specific hardware instance you're tearin' down 🫶

⭐ DESCRIPTION ⭐

Stop the JPEG block, and mark the ring as not ready any more. periodt. 💀

so yeah, two things happen: the block gets stopped, and the ring stops being "ready" — it's officially off duty, retired, logged off, gone to get a lil snack 🍓✨

ngl this is the fini half of the story — if you got here, somebody upstream already decided it's time to wrap things up. iconic behavior.

👑 SEE ALSO 👑

the kernel file lives right here, mwah 💖:

and here's the whole friend group, all of them, no one left out (i would never 😭):

like look at that lineup. main character energy across the board 🌈🔥

and that's the page!! 🧚 this lil gem comes from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's jpeg_v4_0_hw_fini(9) — go forth and fini responsibly bestie 💜🎀
