💅 jpeg_v4_0_3_dec_ring_emit_ib — bestie's guide to the Kernel API Manual ✨

okay so this is a page from the Kernel API Manual and it's genuinely so niche and so iconic — we're talking the JPEG decoder ring for jpeg_v4_0_3 on amdgpu. grab a lil snack, this one's short but she serves 🍓

🌸 NAME 🌸

jpeg_v4_0_3_dec_ring_emit_ib — literally just "execute indirect buffer." that's the whole vibe. she does one thing and she does it 💅

🦋 SYNOPSIS 🦋

void jpeg_v4_0_3_dec_ring_emit_ib (struct amdgpu_ring *ring , struct
amdgpu_job *job , struct amdgpu_ib *ib , uint32_t flags );

no return value, she gives void, she gives mysterious, she gives "i don't owe you a status code" 😌✨

🎀 ARGUMENTS 🎀

four lil besties walk into a function:

  • ring — an amdgpu_ring pointer, fr fr. the ring. the whole main character energy lives here 👑
  • job — the job you're pulling the vmid from. yes, specifically for the vmid. that's her whole purpose in this friend group 🫶
  • ib — the indirect buffer you're about to execute. the guest of honor at this function 💖
  • flags — unused. she's invited but she's just standing in the corner sipping water 🙈 literally does nothing here, no cap

⭐ DESCRIPTION ⭐

Write ring commands to execute the indirect buffer.

that's it. that's the whole description. short queen. she writes the commands to the ring, the indirect buffer gets executed, mic drop, periodt 🔥

🌈 SEE ALSO 🌈

okay this is the part where the page goes absolutely feral with cross-references, and we respect it:

Kernel file ./drivers/gpu/drm/amd/amdgpu/jpeg_v4_0_3.c

and the whole squad:

like, the getters, the setters, the inserters, the fence-emitter — the entire family tree is right there. iykyk 🧚💜

quick note bestie: this page lives at ./drivers/gpu/drm/amd/amdgpu and it's dated October 2026 — so yeah, she's from the future, we stan a forward-thinking manpage 🦋✨ mwah, ily, go read the other jpeg_v4_0_3 pages, slay 💖🎀
