💅 sdma_v4_4_2_inst_enable(9) — Kernel API Manual, section 9 🎀

okay so bestie, gather round, because we're about to talk about the AMDGPU SDMA instance enable function and honestly it's kind of a big deal. this is sdma_v4_4_2_inst_enable from the Linux kernel API manual, section 9 (that's the kernel-functions section, iykyk), and it lives in ./drivers/gpu/drm/amd/amdgpu/sdma_v4_4_2.c. no cap, this little void function is out here literally stopping and un-stopping async DMA engines. main character energy fr fr 💜

✨ NAME ✨

sdma_v4_4_2_inst_enable — stop the async dma engines 🌸

🦋 SYNOPSIS 🦋

void sdma_v4_4_2_inst_enable (struct amdgpu_device *adev , bool enable ,
       uint32_t inst_mask );

that's the whole signature, copy it exactly, don't get creative with it 🙈

💖 ARGUMENTS 💖

  • adev — amdgpu_device pointer. the whole device vibe check right there, bestie 🫶
  • enable — enable/disable the DMA MEs. it's a bool, so it's giving yes-or-no, on-or-off, no in-between 💅
  • inst_mask — mask of dma engine instances to be enabled. this is where you tell it which instances you're talking about 🔥

⭐ DESCRIPTION ⭐

Halt or unhalt the async dma engines. that's it, that's the whole thing — but it's iconic 💀✨

like, lowkey that's a two-line description and she ate. one function, one job: halt them, or unhalt them. dive into it, bestie 🎀

🌈 SEE ALSO 🌈

literally the entire sdma_v4_4_2 extended universe, and you KNOW we're listing every single one because we don't skip 🧚

and that's the page, bestie 🥰 straight from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, manual section 9 of the Kernel API Manual. go forth and enable (or disable, your call) those async dma engines responsibly. mwah 💋💖
