amdgpu_ih_decode_iv_helper(9)

✨ NAME ✨

ok so this is amdgpu_ih_decode_iv_helper — straight out of the Kernel API Manual, bestie — and it does literally one iconic thing: it decodes an interrupt vector. that's the whole vibe. 💅

🌸 SYNOPSIS 🌸

void amdgpu_ih_decode_iv_helper (struct amdgpu_device *adev , struct
       amdgpu_ih_ring *ih , struct amdgpu_iv_entry *entry );

💖 ARGUMENTS 💖

• adev — an amdgpu_device pointer. that's your device, your main character. 🫶
• ih — the ih ring you're gonna process. yes bestie, that ring. 🎀
• entry — the IV entry. the little guy getting filled in. 🌸

🦋 DESCRIPTION 🦋

okay so here's the tea: this function decodes the interrupt vector sitting at the current rptr position — and on top of that, it also advances that position for Vega10 and later GPUs. so it's giving "read and move on," no cap. 🔥

like, the whole friend group, honestly. go say hi. 👑

ngl that's the entire page — no hidden lore, no surprise flags, just a tiny interrupt-vector decoding queen. periodt. 💀

and that's a wrap, bestie!! this one shipped from ./drivers/gpu/drm/amd/amdgpu and the date on it is October 2026 — so go forth and decode those IVs, you gorgeous genius. 🍓🧚💜
