rvt_send_cq(9)

💅 rvt_send_cq(9) — the Kernel API Manual page, bestie edition 🎀

Okay so this is from the Kernel API Manual, section 9, and the page is called rvt_send_cq. Buckle up, it's a short one but it ate. ✨

---

✨ NAME ✨

rvt_send_cq — literally just "add a new entry to completion queue by send queue" 🦋

---

🌸 SYNOPSIS 🌸

void rvt_send_cq (struct rvt_qp *qp , struct ib_wc *wc , bool solicited
);

That's it. That's the whole vibe check. Returns void, so no return value drama. 💀

---

🎀 ARGUMENTS 🎀

• qp — the send queue ✨ (yes the whole argument description is just "send queue", keep up bestie)
• wc — the work completion entry to add 🫶
• solicited — true if the entry is solicited, false if it's not 👑

---

🔥 DESCRIPTION 🔥

So like, this one is a wrapper function for the rvt_enter_cq function call by send queue — that's the whole bit. 🧚

And here's the important part, bestie, don't skip it: if rvt_cq_enter returns false, that means the cq is full, and the qp gets put into an error state. 😭 So yeah, false = bad vibes, cq full, qp in error state, periodt.

ngl this is the kind of function where the caveat is the whole plot — a false from rvt_cq_enter isn't just "no thanks", it flips your qp into an error state. Respect the return value. 💅
