✨ sdma_v7_0_ring_get_wptr(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for sdma_v7_0_ring_get_wptr 💅 this is a lil function from the Kernel API Manual and honestly she's giving "quiet luxury" — small, does one thing, eats every time 🎀

---

🌸 NAME 🌸

sdma_v7_0_ring_get_wptr — get the current write pointer 🦋

like... literally that's her whole job. get the write pointer. iconic behavior, no notes ✨

---

💖 SYNOPSIS 💖

uint64_t sdma_v7_0_ring_get_wptr (struct amdgpu_ring *ring );

so she takes one struct amdgpu_ring * and hands you back a uint64_t. simple. clean. main character energy 🫶

---

👑 ARGUMENTS 👑

• ring — amdgpu ring pointer 💫 (yes bestie, that's the whole arg list, she doesn't need anything else, she's low maintenance like that)

---

⭐ DESCRIPTION ⭐

Get the current wptr from the hardware. 🔥

that's it. that's the function. she talks to the hardware, she asks "hey where's the write pointer at rn", and she brings it back to you. no cap, no drama, just vibes and a uint64_t 🌈

okay so she does NOT exist in a vacuum, she's part of a whole friend group of sdma_v7_0 functions and you should absolutely meet the rest of them 💜

bestie reminder: she only reads the write pointer. if you wanted to change it you'd need sdma_v7_0_ring_set_wptr(9) — different girl, different job 🙈

okay that's the whole page, mwah 💋 this one came to you from the ./drivers/gpu/drm/amd/amdgpu crew and she's dated October 2026 ⭐ ty for reading bestie, go get that write pointer, slay 🧚‍♀️
