💖 sdma_v6_0_rlc_resume(9) 💖

okay so this is a page from the Kernel API Manual — yes bestie, the kernel has lore too — and today's main character is sdma_v6_0_rlc_resume, which sets up and starts the async dma engines. no cap, that's literally the whole vibe. ✨

🎀 NAME 🎀

sdma_v6_0_rlc_resume — setup and start the async dma engines 🦋

---

🌸 SYNOPSIS 🌸

int sdma_v6_0_rlc_resume (struct amdgpu_device *adev );

like, it takes one arg and gives you back an int. simple. iconic. 💅

---

✨ ARGUMENTS ✨

• adev — an amdgpu_device pointer, aka the whole device situation you're handing over 🫶

---

💜 DESCRIPTION 💜

so what it does: it sets up the compute DMA queues and then enables them. that's the assignment and it ate. 🔥

return value tea ☕:

• 0 means success — slay, we love a zero 💖
• anything else (an error) means failure — 😭 not the vibe, but at least it tells you

ngl bestie, if you're poking at these you're already deep in the amdgpu trenches — iykyk 💀

okay that's the whole page, mwah 💋 — this lil number lives at ./drivers/gpu/drm/amd/amdgpu and the version stamp says October 2026, so yeah, she's from the future and she's still serving. 🧚‍♀️ periodt. ⭐
