jpeg_v1_0_de...ing_get_wptr(9)

💖 NAME 💖

okay bestie, so jpeg_v1_0_decode_ring_get_wptr — say that five times fast, i dare you — is literally the function that gets the write pointer. that's it. that's the whole vibe. it's in the Kernel API Manual btw, so you know it's official 👑

---

✨ SYNOPSIS ✨

uint64_t jpeg_v1_0_decode_ring_get_wptr (struct amdgpu_ring *ring );

that's the whole signature, no cap. it takes exactly one thing and gives you back a uint64_t. simple. clean. iconic. 💅

---

🎀 ARGUMENTS 🎀

• ring — an amdgpu_ring pointer. that's the one (1) thing you gotta hand over. yes, it has to be a pointer. no, you can't skip it. 🫶

---

🦋 DESCRIPTION 🦋

so what does it actually do? it returns the current hardware write pointer. that's the entire description, bestie — the hardware has a write pointer, and this function goes and gets it for you. it's giving personal assistant energy, honestly. 🌸

like, it's not complicated and it doesn't need to be. get the pointer. return the pointer. slay. ⭐
