💖 sdma_v7_1_inst_rlc_resume(9) — Kernel API Manual 💖

okay so bestie, welcome to the group chat for sdma_v7_1_inst_rlc_resume(9) in the Kernel API Manual. this is the lowkey iconic resume helper for async DMA stuff, and we're gonna read it together. no cap. 🫶

✨ NAME ✨

sdma_v7_1_inst_rlc_resume — setup and start the async dma engines 🌸

🌸 SYNOPSIS 🌸

int sdma_v7_1_inst_rlc_resume (struct amdgpu_device *adev , uint32_t
       inst_mask );

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer. that’s the device bestie, literally 💅
• inst_mask — mask of dma engine instances to be enabled. think of it as the guest list for which DMA engine instances get to show up ✨

💅 DESCRIPTION 💅

okay so what does this icon do? it sets up the compute DMA queues and enables them. that’s the whole main-character move. if it works, it returns 0 for success; if it doesn’t, it returns error for failure. periodt. 💖
