💅 sdma_v5_0_gfx_resume — the kernel API manual, bestie edition ✨

okay so picture this: you're deep in the sdma_v5_0_gfx_resume(9) manpage from the Kernel API Manual, and honestly? it's giving "small function, big job." let me walk you through it 🫶

✨ NAME ✨

sdma_v5_0_gfx_resume — setup and start the async dma engines. that's it, that's the whole vibe. she sets things up, she starts things up. main character energy fr 💅

🦋 SYNOPSIS 🦋

int sdma_v5_0_gfx_resume (struct amdgpu_device *adev );

like, she takes exactly one thing and she returns an int. no cap, that's the whole signature 🎀

🌸 ARGUMENTS 🌸

  • adev — an amdgpu_device pointer. that's your amdgpu device, bestie, the whole little universe she's about to go set up 😌

💖 DESCRIPTION 💖

so what does she actually do? she sets up the gfx DMA ring buffers and then enables them — specifically for NAVI10 🎀 (iykyk, different chip, different resume path).

and the return sitch is very straightforward: returns 0 for success, error for failure. that's it. 0 = slay, anything else = not slay 😭

👑 SEE ALSO 👑

the source she lives in, first of all:

  • the kernel file ./drivers/gpu/drm/amd/amdgpu/sdma_v5_0.c 🦋

and then her whole friend group, the entire group chat, no one left out:

like, twenty-six functions. twenty-six!! the way she's connected to literally everyone in the amdgpu sdma_v5_0 family 🌈💜

lowkey a reminder that this page is from the Kernel API Manual, sourced out of ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — so if you're reading this from the future, hey bestie, hope the DMA engines are still slaying 🌸💀

okay that's the page, go forth and resume those gfx DMA rings responsibly 🧚‍♀️⭐ periodt.
