cik_cp_gfx_fini(9)

💅 cik_cp_gfx_fini(9) — Kernel API Manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual (yes the whole manual, we're fancy) and it's about cik_cp_gfx_fini, which is genuinely such a good-little-cleanup-function, we love a function that knows how to say goodbye ✨

---

🌸 NAME 🌸

cik_cp_gfx_fini — stop the gfx ring 🛑

like that's literally her whole job. she stops the gfx ring. iconic behavior.

---

🦋 SYNOPSIS 🦋

void cik_cp_gfx_fini (struct radeon_device *rdev );

no cap, that's the whole signature. returns void because she doesn't gossip, she just does the thing 💅

---

💖 ARGUMENTS 💖

• rdev — a radeon_device pointer 🫶 that's it, that's the one (1) argument. she only needs the one.

---

🔥 DESCRIPTION 🔥

So what does she actually do? Two things, and she does them well:

• Stop the gfx ring 🛑
• Tear down the driver ring info 🧹

that's the vibe. stop the ring, clean up the ring info, walk away like a main character. periodt. 💜
