cik_get_xclk(9)

💅 cik_get_xclk(9) 💅

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, yes it's a whole vibe, and yes we're about to get into it. This one's a tiny little function page, so grab your iced coffee and let's go 🎀

---

✨ NAME ✨

cik_get_xclk — get the xclk 🌸

like. that's literally it. that's the whole job. get the xclk. she's a one-line queen and she ate 💅

---

✨ SYNOPSIS ✨

u32 cik_get_xclk (struct radeon_device *rdev );

so you hand her a struct radeon_device * named rdev and she hands you back a u32. simple. iconic. no cap 🫶

---

✨ ARGUMENTS ✨

• rdev — a radeon_device pointer 💖 that's the whole argument, that's the whole girl. she needs her radeon device and she's good to go.

---

✨ DESCRIPTION ✨

Returns the reference clock used by the gfx engine (CIK). ⭐

that's the tea. reference clock. gfx engine. CIK. she returns it, you use it, everybody's happy. no side quests, no surprises, just a clock value doing main character energy 🔥

---

✨ SEE ALSO ✨

okay so this is the part where the manpage goes absolutely feral and lists basically every CIK function in existence — and honestly? respect. here's the full crew, no gatekeeping, iykyk 👑

like i said. the whole friend group showed up to the party 🌈

lowkey a reminder bestie: this page gives you the reference clock, and that's all it does. don't go making her do other stuff, that's not her era 🙈

and that's the page!! 🎀 brought to you by the source <pink>./drivers/gpu/drm/radeon</pink>, dated October 2026, filed under cik_get_xclk(9) — mwah, love u, go read the other 90 CIK pages, periodt 💜✨
