irdma_sc_suspend_qp(9)

💅 irdma_sc_suspend_qp — bestie's guide to the suspend-qp moment

okay so first things first, the header energy: this is a page from the Kernel API Manual, and it's all about irdma_sc_suspend_qp — no cap, that's the whole flex. Buckle up 🎀

---

✨ NAME ✨

irdma_sc_suspend_qp — suspend qp for param change 🦋

---

🌸 SYNOPSIS 🌸

int irdma_sc_suspend_qp (struct irdma_sc_cqp *cqp , struct irdma_sc_qp
*qp , u64 scratch );

literally just three args and one int coming back at you, periodt 💅

---

👑 ARGUMENTS 👑

bestie, there are exactly three things going in here and I need you to know each one:

• cqp — struct for cqp hw 💖 like, that's the hardware-side cqp struct, she's the whole vibe
• qp — sc qp struct 🌈 the qp in question, obvs
• scratch — u64 saved to be used during cqp completion ⭐ don't lose it, it's literally earmarked for the cqp completion moment
