uvd_v6_0_ring_set_wptr(9)

💫 uvd_v6_0_ring_set_wptr(9) 💫

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil function from the AMDGPU fam and it's short but she's important, no cap.

---

🌸 NAME 🌸

uvd_v6_0_ring_set_wptr — set write pointer, that's literally the whole job 🎀

---

🦋 SYNOPSIS 🦋

void uvd_v6_0_ring_set_wptr (struct amdgpu_ring *ring );

that's it. that's the whole signature. returns nothing (void), takes one pointer. clean, minimal, iconic 💅

---

💖 ARGUMENTS 💖

• ring — amdgpu_ring pointer 👑 like, a pointer to a struct amdgpu_ring. that's the whole arg. she's the main character here, everything happens through her.

---

✨ DESCRIPTION ✨

Commits the write pointer to the hardware 🔥

fr fr that's it — it takes the write pointer and commits it to the hardware. no side quests, no extra params, just the commit. the way that this lil function just does its one thing is honestly so refreshing 😌🫶

lowkey a reminder: this is the v6.0 UVD ring flavour specifically, so don't go mixing her up with the enc ring variants or the getters, iykyk 💀
