💅 jpeg_v2_5_sw_fini — Kernel API Manual, section 9 ✨

okay so bestie, we're in the Kernel API Manual (section 9, drivers-adjacent, very demure) and today's main character is jpeg_v2_5_sw_fini. yes it's a mouthful, yes it's iconic, let's get into it 🫶

🌸 NAME 🌸

jpeg_v2_5_sw_fini — the sw fini for the JPEG block ✨

like, it's the software-finish-up girlie for the JPEG hardware block. she wraps things up. she cleans up. she does not make a whole thing of it 💅

🦋 SYNOPSIS 🦋

int jpeg_v2_5_sw_fini (struct amdgpu_ip_block *ip_block );

that's the whole signature, no cap. returns an int, takes exactly one arg. slay 🔥

🎀 ARGUMENTS 🎀

  • ip_block — a pointer to the struct amdgpu_ip_block for this hw instance. one block, one hw instance, very "this is my specific one, not the other one" energy 👑

🌈 DESCRIPTION 🌈

JPEG suspend and free up sw allocation 💖

so yeah — it suspends the JPEG situation and then frees up the software allocation. that's the vibe. that's the whole job. she's not doing extra credit, she's doing exactly what the line says 🧚

lowkey important: this is the software fini, not the hardware one. don't mix them up bestie, they're different girlies (see below 👀).

⭐ SEE ALSO ⭐

the kernel file herself, the source of truth:

  • ./drivers/gpu/drm/amd/amdgpu/jpeg_v2_5.c

and the whole friend group, in this exact order because we respect the lore:

notice how jpeg_v2_6_dec_ring_insert_start(9) and jpeg_v2_6_dec_ring_insert_end(9) crashed the v2_5 party? yeah. cross-version besties. we love to see it 🌸

and that's the page, bestie 🎀 this cutie lives in ./drivers/gpu/drm/amd/amdgpu and the manual page is dated October 2026 — go forth and fini your sw responsibly, ily, mwah 💜🦋
