💖 jpeg_v5_0_2_dec_ring_set_wptr — set write pointer 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a tiny little function from the AMDGPU JPEG squad and honestly she's short but she MATTERS 💅

---

✨ NAME ✨

jpeg_v5_0_2_dec_ring_set_wptr — set write pointer 🎀

---

🌸 SYNOPSIS 🌸

void jpeg_v5_0_2_dec_ring_set_wptr (struct amdgpu_ring *ring );

like, that's it. that's the whole signature. no cap. 🫶

---

🦋 ARGUMENTS 🦋

• ring — an amdgpu_ring pointer 👑 that's the one and only thing she takes

---

💜 DESCRIPTION 💜

so what does she actually do? she commits the write pointer to the hardware 🔥 that's the whole vibe honestly — the write pointer gets handed off to the hardware, periodt. ✨

ngl for a one-liner she's carrying a lot of responsibility 😭 but that's main character energy for you 💅
