cik_cp_compute_start(9)

✨ cik_cp_compute_start(9) ✨

okay bestie, so this one is from the Kernel API Manual — and it's literally the glow-up moment for the compute queues. it's giving "press play on the whole compute engine" energy, and i'm obsessed 💅

---

✨ NAME ✨

cik_cp_compute_start — start the compute queues 🎬🔥

---

✨ SYNOPSIS ✨

okay so the vibe check starts here, and this is the exact signature, no cap:

int cik_cp_compute_start (struct radeon_device *rdev );

---

✨ ARGUMENTS ✨

• rdev — a radeon_device pointer 🫶 (yes, THE device. the main character. we love them.)

---

✨ DESCRIPTION ✨

so basically this bad boy enables the compute queues ✨ that's the whole gig. it returns 0 for success, and an error for failure 😭 that's it, that's the function, periodt.

• 0 → slay, we're good ✅
• error → not the vibe, something went wrong 💀
