✨ cik_sdma_rlc_resume(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for cik_sdma_rlc_resume(9) — yes that's the whole title, she's a mouthful, but she's also kind of iconic 🎀

---

💅 NAME

cik_sdma_rlc_resume — setup and start the async dma engines 🦋

---

⭐ SYNOPSIS

int cik_sdma_rlc_resume (struct radeon_device *rdev );

like, that's it, that's the whole call. one argument, one int coming back at you, no cap ✨

---

🌸 ARGUMENTS

• rdev — a radeon_device pointer, just a lil pointer to the radeon device, that's her whole job 🫶

---

🔥 DESCRIPTION

so what she does is: set up the compute DMA queues and enable them (that's CIK, for the record) 💖

and then she reports back — returns 0 for success, and an error for failure. so like, if you get 0 you're slaying, and if you get an error… well 😭 at least she told you!
