π sdma_v6_0_gfx_resume(9) β like, the whole manual, bestie
okay so you opened the Kernel API Manual and landed on sdma_v6_0_gfx_resume(9)?? slay, you're in the right place. sit down, hydrate, let's get into it π«Ά
β¨ NAME β¨
sdma_v6_0_gfx_resume β setup and start the async dma engines π
like literally, that's the whole vibe. we're setting them up and starting them. no cap.
π¦ SYNOPSIS π¦
int sdma_v6_0_gfx_resume (struct amdgpu_device *adev );
that's it. that's the whole function signature. she's short and she knows it π
πΈ ARGUMENTS πΈ
adevβ anamdgpu_devicepointer. that's the whole description, bestie, the original said so and I'm not about to invent lore. it's the amdgpu device pointer. mwah β¨
π DESCRIPTION π
So what does she actually do? She sets up the gfx DMA ring buffers and enables them. iconic behavior honestly.
Return values, listen up:
- returns
0for success π₯³ - returns an error for failure π
that's the tea. that's the whole tea.
π₯ SEE ALSO π₯
okay this list is LONG and honestly it ate, so let's give it the respect it deserves. the kernel file lives at:

go read them, iykyk π
also the source path is./drivers/gpu/drm/amd/amdgpu, the date on this one is October 2026, and it's pagesdma_v6_0_gfx_resume(9)of the Kernel API Manual. not me saving the boring bits for last π
anyway that's the page!! go forth and resume those async dma engines, bestie. you're the main character of this kernel module fr fr π§πβ¨
