cik_cp_compute_fini(9)

💅 cik_cp_compute_fini — Kernel API Manual, bestie edition 💅

okay so quick vibe check: this is a page from the Kernel API Manual, and it's about cik_cp_compute_fini. it's short, it's sweet, it's the cleanup era of the function world. let's get into it 🎀

---

✨ NAME ✨

cik_cp_compute_fini — stop the compute queues 🛑

like, that's literally it. the compute queues? they're done. fini. periodt. 💅

---

✨ SYNOPSIS ✨

void cik_cp_compute_fini (struct radeon_device *rdev );

no return value, she just does her thing and dips. 🦋

---

✨ ARGUMENTS ✨

• rdev — a radeon_device pointer 👑. yes that's the whole description. it's the radeon device, it's a pointer, we love a simple queen.

---

✨ DESCRIPTION ✨

so what does she do? two things, and honestly she eats both of them:

• stop the compute queues 🛑
• tear down the driver queue info 🧹

that's the whole lore. no cap, that's the entire description in the original and i'm not gonna invent drama that isn't there. it's a teardown function, it stops the compute queues and it tears down the driver queue info. clean, iconic, no notes. ✨

ngl this is the kind of function that shows up at the end of the story, not the beginning — it's the "everybody go home" of the compute queue world. 🌙

like… dce8_average_bandwidth_vs_dram_bandwidth_for_display(9)?? that name is a whole paragraph, she's giving main character energy and i'm obsessed 😭🔥

and that's the page!! 🫶 this little cutie lives in ./drivers/gpu/drm/radeon, it's dated October 2026, and if you ever need to find her again just call her by name: cik_cp_compute_fini(9) 💖✨
