📦 version 7.3.1, in nixpkgs unstable

💅 sdma_v5_0_ring_test_ib — from the Kernel API Manual ✨

okay so bestie, welcome to the glow-up doc for sdma_v5_0_ring_test_ib 💖 this is one of those fancy Kernel API Manual pages, and yes it's giving "graphics driver internals" realness, so let's get into it 🎀

✨ NAME ✨

sdma_v5_0_ring_test_ib — literally just here to test an IB on the DMA engine 🦋

✨ SYNOPSIS ✨

int sdma_v5_0_ring_test_ib (struct amdgpu_ring *ring , long timeout );

✨ ARGUMENTS ✨

  • ring — the amdgpu_ring structure that's holding all the ring information, like it's carrying the whole group chat 🫶
  • timeout — the timeout value, measured in jiffies, or MAX_SCHEDULE_TIMEOUT if you're feeling unbothered and infinite 😌

✨ DESCRIPTION ✨

So what it does is test a simple IB in the DMA ring (NAVI10) 🔥 and it returns 0 on success, or an error on failure. That's the whole vibe check: zero means slay, anything else means something went wrong 😭

✨ SEE ALSO ✨

the kernel file to go peek at is ./drivers/gpu/drm/amd/amdgpu/sdma_v5_0.c 👑

and honestly the whole squad, all of these icons:

and that's the whole page, no cap 🌈 this lil beauty lives over in ./drivers/gpu/drm/amd/amdgpu, it's dated October 2026, and it's part of the Kernel API Manual — go off, you understood the assignment 💜🎀✨
