β¨ sdma_v7_0_rlc_resume(9) β¨
Okay bestie, buckle up π this is a page from the Kernel API Manual and it's all about one lil function that wakes up the async DMA engines. She's short, she's sweet, she's lowkey doing a lot of heavy lifting. Let's get into it π«Ά
πΈ NAME πΈ
sdma_v7_0_rlc_resume β setup and start the async dma engines</p> π
β SYNOPSIS β
int sdma_v7_0_rlc_resume (struct amdgpu_device *adev );
Like, that's the whole signature. No cap, that's it. π₯
π ARGUMENTS π
adevβ anamdgpu_devicepointer. That's the whole vibe check for this parameter, she's just a pointer to the amdgpu device and we love her for it π
π¦ DESCRIPTION π¦
So what does she actually do? She sets up the compute DMA queues and enables them. That's the entire job description, and honestly? Iconic. π
Return value tea β: it returns 0 for success, and an error for failure. That's the whole story, no plot twists, no hidden lore. β
π SEE ALSO π
The main character source file lives here, in all her glory:
Kernel file ./drivers/gpu/drm/amd/amdgpu/sdma_v7_0.c
And now the whole friend group β literally every single one of these, don't skip a single bestie π§:

Fr fr, that's the entire page. Short king energy but every detail accounted for πβ¨
And that's a wrap, bestie π this came to you from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and honestly? She ate. Periodt. π
