💫 sdma_v2_4_ring_pad_ib — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the sdma_v2_4_ring_pad_ib(9) era 🎀 this is the Kernel API Manual entry for it, and honestly? it's giving "small function, big job." let's get into it 💅

---

✨ NAME ✨

sdma_v2_4_ring_pad_ib — pad the IB to the required number of dw 🫶

like, literally that's the whole vibe. it pads the IB up to the required number of dw, no cap.

---

🌸 SYNOPSIS 🌸

void sdma_v2_4_ring_pad_ib (struct amdgpu_ring *ring , struct amdgpu_ib
*ib );

that's it. that's the whole signature. returns void, so no exit-status drama here, she just does the thing and leaves 😌

---

🦋 ARGUMENTS 🦋

• ring — the amdgpu_ring structure holding ring information 💍 like, this is the ring's whole identity, her main character data
• ib — the indirect buffer to fill with padding 🧚 this is the one getting padded, she's getting stuffed with padding, respectfully

ngl bestie, nothing here is dangerous or deprecated — it's just padding. but fr fr, use the real function names exactly as written, iykyk 🌈
