💅 sdma_v5_2_ring_pad_ib(9) — it's giving "Kernel API Manual" energy ✨

okay so bestie, welcome to the glow-up of the sdma_v5_2_ring_pad_ib page from the Kernel API Manual. grab your iced coffee, we're learning about padding an indirect buffer. yes, really. it's lowkey iconic 🎀

🌸 NAME 🌸

sdma_v5_2_ring_pad_ib — pad the IB. that's it. that's the whole job. she pads. periodt 💅

---

✨ SYNOPSIS ✨

void sdma_v5_2_ring_pad_ib (struct amdgpu_ring *ring , struct amdgpu_ib
*ib );

like literally just hand her a ring and an ib and she'll do the rest, no cap 🫶

---

🦋 ARGUMENTS 🦋

• ring — the amdgpu_ring structure that's holding all the ring information. she's the main character, she holds the data 💖
• ib — the indirect buffer you want filled up with padding. yes bestie, we're filling her up, respectfully 🙈

---

⭐ DESCRIPTION ⭐

so here's the vibe check: this function pads the IB with NOPs until it hits a boundary that's a multiple of 8. that's the tea. NOPs in, boundaries respected, everybody slays 🔥

ngl, "pad the IB" sounds like a group chat message but it's fr fr real kernel code 😭
