🎀 sdma_v7_1_inst_enable(9) 🎀

okay bestie, so this is a page straight outta the Kernel API Manual — yes, we're in kernel-land now, and yes you're gonna slay it 💅 This one's about sdma_v7_1_inst_enable, and tbh the vibe is very much "flip the async dma engines on or off, no biggie."

✨ NAME ✨

sdma_v7_1_inst_enable — stop the async dma engines 🛑

no fr, that's literally what the name section says: stop the async dma engines. (and yeah, before you @ me, the description below is a little more chill about it — it does both directions. stay with me 🫶)

🌸 SYNOPSIS 🌸

void sdma_v7_1_inst_enable (struct amdgpu_device *adev , bool enable ,
       uint32_t inst_mask );

like, it returns void — nothing comes back out, it's giving "I do the thing and I leave" energy ✨

🦋 ARGUMENTS 🦋

  • adev — an amdgpu_device pointer 💖 that's your whole GPU device situation, the main character of this function call ngl
  • enable — the bool that decides it all: enable/disable the DMA MEs 👑 it's literally the on/off switch, iconic
  • inst_mask — mask of dma engine instances to be enabled 🎀 so you can pick which instances get the treatment, not all of them have to show up to the party

💜 DESCRIPTION 💜

Halt or unhalt the async dma engines 💀 that's it, that's the whole bit. You're either putting them on pause or letting them breathe again, iykyk.

🌈 SEE ALSO 🌈

the kernel file lives here, bestie:

and here's the whole friend group — every single one of these is a real entry you can go look up, no cap:

and that's the whole page, bestie!! 🧚‍♀️ this beauty ships from the source tree at ./drivers/gpu/drm/amd/amdgpu, version-dated October 2026 — so go forth, halt and unhalt those engines, and remember: main character energy only 💅✨👑
