sdma_v5_0_start(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

✨ NAME ✨

sdma_v5_0_start β€” bestie, this is the one that sets up and starts the async dma engines πŸ’…

so like, real talk, this page lives in the Kernel API Manual, and it's all about one single function. that's it. that's the whole vibe. πŸ¦‹


🌸 SYNOPSIS 🌸

int sdma_v5_0_start (struct amdgpu_device *adev );

yep, that's the whole signature. one argument, returns an int. iconic behavior honestly πŸŽ€


🫢 ARGUMENTS 🫢

  • adev β€” an amdgpu_device pointer. that's the whole thing, she just needs the device and she's off πŸ’–

πŸ”₯ DESCRIPTION πŸ”₯

okay so here's the tea β˜• β€” sdma_v5_0_start sets up the DMA engines and then enables them (this is the NAVI10 squad, iykyk).

and the return situation? it returns 0 for success, or an error for failure. no cap, that's it. not me being obsessed with a function that just... does its job 🧚


πŸ‘‘ SEE ALSO πŸ‘‘

the kernel file where all the magic lives:

  • ./drivers/gpu/drm/amd/amdgpu/sdma_v5_0.c

and bestie, the whole friend group 🫢 β€” every single one of these:

like, the whole squad showed up. main character energy all around 🌈


πŸ’€ reminder bestie: 0 means slay, anything else means something went wrong. don't @ me.

okay and for the lil sign-off πŸŽ€ β€” this whole thing comes from ./drivers/gpu/drm/amd/amdgpu, it's dated October 2026, and it's a proud member of the Kernel API Manual family. periodt. πŸ’œπŸŒΈ

ily, go read your kernel source, mwah 🫢✨
