💅 cik_sdma_get_rptr(9) — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of cik_sdma_get_rptr(9), straight out of the Kernel API Manual. she's a tiny function but she's doing main character work, fr fr 🎀

---

🌸 NAME 🌸

cik_sdma_get_rptr — get the current read pointer 💫

like literally that's her whole job and she ate 💅

---

✨ SYNOPSIS ✨

uint32_t cik_sdma_get_rptr (struct radeon_device *rdev , struct
radeon_ring *ring );

that's the whole vibe check right there 🦋 she takes two pointers and hands you back a uint32_t, no cap.

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer 🫶 so like, the whole device situation
• ring — a radeon_ring pointer 🌈 the specific ring we're peeking at

---

💖 DESCRIPTION 💖

Get the current rptr from the hardware (CIK+). 🌟

that's it, that's the tea ☕ she goes and asks the hardware what the read pointer is at right now, and this is the CIK+ era version of that move 🔥 iconic behaviour, no notes.

ngl it's giving "short but essential" — the whole function is one job and she does it 💀
