💅 sdma_v5_2_enable(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this is a lil' page about one function, and honestly? it's giving "small but mighty". let's get into it 🫶

✨ NAME ✨

sdma_v5_2_enable — stop the async dma engines 😭

(no fr, that's what the NAME line says. the description down there is gonna give you the full picture, but yes, the headline is stop the async dma engines. iconic of it.)

🌸 SYNOPSIS 🌸

void sdma_v5_2_enable (struct amdgpu_device *adev , bool enable );

so it returns void (nothing comes back out, it just does the thing 💅), and it takes exactly two things: a struct amdgpu_device *adev and a bool enable. that's it, that's the whole vibe check.

🎀 ARGUMENTS 🎀

  • adev — the amdgpu_device pointer 💖 like, the device we're messing with. main character energy.
  • enable — enables/disables the DMA MEs. this is the little switch that decides which direction we're going in 👑

🦋 DESCRIPTION 🦋

Halt or unhalt the async dma engines 🔥

that's the whole bit ngl. you're either putting those engines to sleep or waking them back up — and enable is the flag that tells it which one. one bool, two destinies, no cap 🧚

💜 SEE ALSO 💜

the kernel file lives right here, bestie:

./drivers/gpu/drm/amd/amdgpu/sdma_v5_2.c

and here's the whole friend group — every single one of these is a real reference on the page, so keep them close 🫶

and that's the page, bestie! 🍓 this whole thing comes out of ./drivers/gpu/drm/amd/amdgpu and it's dated October 2026 — so yeah, mark your calendar, the future called and it's still explaining SDMA to us 💀💖 slay, go read the source, ily, bye!! 🌈⭐
