💖 NAME 💖

sdma_v3_0_ring_get_wptr - get the current write pointer

hii bestie, welcome to the sdma_v3_0_ring_get_wptr(9) page from the Kernel API Manual 💅. This is the little function that grabs the current write pointer, and yes, it's giving main-character kernel energy 👑.

✨ SYNOPSIS ✨

uint64_t sdma_v3_0_ring_get_wptr (struct amdgpu_ring *ring );

🎀 ARGUMENTS 🎀

• ring — amdgpu ring pointer 🫶. That's the ring we're working with, periodt.

🦋 DESCRIPTION 🦋

Okay so this one gets the current wptr from the hardware (VI+) ⭐. That's literally the whole vibe: current write pointer, straight from the hardware. No cap. Slay.
