💖 sdma_v3_0_rlc_resume(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a lil function page about waking up the async dma engines, and honestly? it's giving "small function, big job" energy. let's get into it ✨

🌸 NAME 🌸

sdma_v3_0_rlc_resume — setup and start the async dma engines 🦋

✨ SYNOPSIS ✨

int sdma_v3_0_rlc_resume (struct amdgpu_device *adev );

like, that's the whole signature. one arg, one int coming back at you. no cap. 💅

🎀 ARGUMENTS 🎀

  • adev — an amdgpu_device pointer. that's it, that's the whole vibe. it's the device you're working on, she's the main character here 👑

🌈 DESCRIPTION 🌈

okay so here's what's actually going down: this function sets up the compute DMA queues and enables them (VI). that's the whole flex 🔥

and the return? she tells you how it went:

  • returns 0 for success — slay, we love a clean exit 💖
  • returns error for failure — 😭 not every day is your day

fr fr, that's the entire description. short and iconic, periodt. ⭐
