sdma_v3_0_ring_pad_ib(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

okay so bestie, this is sdma_v3_0_ring_pad_ib(9) — she's a kernel function from the Kernel API Manual, and her whole entire job is padding the IB to the required number of dw. that's it. that's the gig. she's not doing anything else, she's just adding padding until the number is right, and honestly? iconic. 💖

✨ SYNOPSIS ✨

void sdma_v3_0_ring_pad_ib (struct amdgpu_ring *ring , struct amdgpu_ib
*ib );

no return value, it's void, it just does the thing. periodt. 🫶

🎀 ARGUMENTS 🎀

  • ring — the amdgpu_ring structure holding ring information. she's holding the ring info, that's her whole lore. 💍
  • ib — the indirect buffer to fill with padding. yes, this one gets filled. with padding. that's literally what the function name promised and she delivers. 😭✨

🌈 SEE ALSO 🌈

so if you wanna go read the source yourself (and honestly, why wouldn't you, she's lowkey sliving in here), the kernel file is:

./drivers/gpu/drm/amd/amdgpu/sdma_v3_0.c

and here's the full squad, no cap, every single one of these cross-references is real and you should look at them all:

like, the way that whole list of sdma_v3_0_* functions is basically her extended friend group 🦋 go say hi to all of them

🌸 okay that's the whole page bestie, hope u learned something about padding, mwah 🌸

signing off with the deets: this came from the Kernel API Manual, the source lives under ./drivers/gpu/drm/amd/amdgpu, and the date on it is October 2026. bye, love u, drink water 💜✨🎀
