💫 jpeg_v4_0_3_dec_ring_get_wptr — Kernel API Manual ✨

okay so bestie, this is a page straight out of the Kernel API Manual and honestly? it's a little one but it's mighty. we're talking jpeg_v4_0_3_dec_ring_get_wptr, which lowkey does exactly one thing and does it slayfully. let's get into it 🎀

---

🌸 NAME 🌸

jpeg_v4_0_3_dec_ring_get_wptr — get write pointer. that's it, that's the whole vibe. short, sweet, iconic 👑

---

🦋 SYNOPSIS 🦋

uint64_t jpeg_v4_0_3_dec_ring_get_wptr (struct amdgpu_ring *ring );

so you call it, you hand it a ring, and it gives you back a uint64_t. easy. no cap 💅

---

💖 ARGUMENTS 💖

• ring — amdgpu_ring pointer. that's your ring, bestie. the one you're asking about. you just pass it on in there 🫶

---

✨ DESCRIPTION ✨

Returns the current hardware write pointer. fr fr, that's the entire plot 😭 it reads the write pointer off the hardware and hands it back to you as a uint64_t. no drama, no side quests, just the pointer. the way that it does one job and does it flawlessly? obsessed 🌟
