💫 sdma_v6_0_ring_get_wptr(9) 💫

okay bestie, welcome to the Kernel API Manual — yes we're reading kernel docs for fun now, this is who we are 💅

---

✨ NAME ✨

sdma_v6_0_ring_get_wptr — get the current write pointer 🎀

---

🌸 SYNOPSIS 🌸

uint64_t sdma_v6_0_ring_get_wptr (struct amdgpu_ring *ring );

like, that's it. that's the whole signature. she's tidy 💖

---

🦋 ARGUMENTS 🦋

• ring — amdgpu ring pointer. that's the one bb, hand her the ring and she'll do her thing 🫶

---

👑 DESCRIPTION 👑

Get the current wptr from the hardware. no cap, that's literally the whole description — she reaches into the hardware and pulls the current write pointer back out for you, returns it as a uint64_t, and minds her own business ⭐
