💅 sdma_v3_0_ctx_switch_enable(9) 💅

okay bestie, welcome to the Kernel API Manual — yes we're literally in the kernel docs rn, and this page is called sdma_v3_0_ctx_switch_enable(9). it's giving niche-but-important, iykyk 🎀

✨ NAME ✨

sdma_v3_0_ctx_switch_enable — stop the async dma engines context switch

like, that's the whole vibe. that's what it does. no cap. 🦋

🌸 SYNOPSIS 🌸

void sdma_v3_0_ctx_switch_enable (struct amdgpu_device *adev , bool
enable );

she takes two things and returns nothing (void, so no receipts, she just does the thing and leaves 💅).

🎀 ARGUMENTS 🎀

  • adev — amdgpu_device pointer. that's your device, your main character, the whole reason we're here 🫶
  • enable — enable/disable the DMA MEs context switch. so like, bool energy: turn it on or turn it off, pick a lane ⭐

🔥 DESCRIPTION 🔥

Halt or unhalt the async dma engines context switch (VI).

that's it, that's the function. you're either pausing that context switch or you're un-pausing it, and it's specifically the (VI) flavor of the async dma engines. no extra lore, no side quests — just halt/unhalt, iconic behavior honestly 👑

🌈 SEE ALSO 🌈

first up, the source file she lives in — literally her address, her home base:

  • Kernel file ./drivers/gpu/drm/amd/amdgpu/sdma_v3_0.c

and now the whole friend group, the entire sdma_v3_0 squad, all present and accounted for (not me listing all of them, but a promise is a promise 💖):

and that's the page!! 🧚 sign-off time: this whole thing lives under ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and yes the title is still sdma_v3_0_ctx_switch_enable(9) because we never forget where we came from 💜 mwah, go halt something (or unhalt it, your call) 🍓
