irdma_puda_ieq_get_ah_info(9)

💖 irdma_puda_ieq_get_ah_info — a Kernel API Manual moment 💖

okay so bestie, we're deep in the irdma driver for real — this page lives in the Kernel API Manual and it's all about one lil function, irdma_puda_ieq_get_ah_info(9). She's giving tiny-but-important energy, ngl.

---

✨ NAME ✨

irdma_puda_ieq_get_ah_info — literally just: get the AH info out of the IEQ buffer. That's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void irdma_puda_ieq_get_ah_info (struct irdma_sc_qp *qp , struct
irdma_ah_info *ah_info );

she returns void, so like… no receipt, no drama, she just does the thing and dips 💅

---

🦋 ARGUMENTS 🦋

• qp — a qp pointer, bestie. the qp in question, right there, pointed at. 🫶
• ah_info — an AH info pointer. that's where the AH info ends up. iconic behaviour fr fr.

💀 reminder: only irdma_puda_ieq_get_ah_info does the get-AH-info-from-IEQ-buffer thing. the rest are just the neighbours, don't get it twisted, iykyk.
