💅 sdma_v7_1_ring_pad_ib(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're literally in the kernel now, main character energy only 🎀

---

🌸 NAME 🌸

sdma_v7_1_ring_pad_ib — pad the IB. that's it. that's the whole job. no cap ✨

---

🦋 SYNOPSIS 🦋

void sdma_v7_1_ring_pad_ib (struct amdgpu_ring *ring , struct amdgpu_ib
*ib );

like, it returns void — it gives nothing back, it just does the thing. icon behavior honestly 👑

---

💖 ARGUMENTS 💖

• ring — amdgpu ring pointer. it's the ring, she's pointer-y, she's amdgpu, you know the vibe 🫶
• ib — indirect buffer to fill with padding. this is the one getting stuffed with NOPs, poor thing 😭

---

🌈 DESCRIPTION 🌈

okay so here's the tea: this function pads the IB with NOPs to a boundary multiple of 8. that's the entire plot. she takes your indirect buffer and fills it with padding so it lands all nice and aligned on a multiple of 8. alignment slay 💅✨

ngl there are zero warnings or bugs listed here — she's a simple function with a simple dream (padding things to a multiple of 8) and honestly? respect 🍓
