💖 vcn_v2_0_dec_ring_get_wptr(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're literally in the kernel docs rn, and honestly? iconic. this one lives in ./drivers/gpu/drm/amd/amdgpu and ngl it's a tiny little function but it has main character energy. let's get into it 🫶

---

✨ NAME ✨

vcn_v2_0_dec_ring_get_wptr — get write pointer

like… it gets the write pointer. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

uint64_t vcn_v2_0_dec_ring_get_wptr (struct amdgpu_ring *ring );

she returns a uint64_t and she takes exactly one (1) argument. no cap. ✨

---

🦋 ARGUMENTS 🦋

• ring — an amdgpu_ring pointer. that's it, that's the argument. your ring. your girl. 💅

---

💜 DESCRIPTION 💜

Returns the current hardware write pointer.

fr fr that's the whole description — this function is short and she knows it. you hand her the ring, she hands you back the hardware's current write pointer as a uint64_t. lowkey elegant, highkey slay. 🔥
