✨ vcn_v4_0_3_unified_ring_get_wptr(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a lil function page about peeking at a hardware write pointer, and it's honestly shorter than my attention span, so let's go 🫶

---

💅 NAME

vcn_v4_0_3_unified_ring_get_wptr — get unified write pointer ✨

---

🦋 SYNOPSIS

uint64_t vcn_v4_0_3_unified_ring_get_wptr (struct amdgpu_ring *ring );

like, that's the whole signature. returns a uint64_t, takes a pointer to a struct amdgpu_ring. slay 💅

---

🎀 ARGUMENTS

• ring — an amdgpu_ring pointer, aka the ring you're being nosy about 👀

---

🌸 DESCRIPTION

Returns the current hardware unified write pointer. that's it. that's the vibe. it just returns the current hardware unified write pointer and honestly? iconic. no cap 💯

ngl if you're tryna follow the pointer drama from start to finish, read the get_rptr one and the set_wptr one right next to this one. iykyk 🤝
