rvt_recv_cq(9)

💅 NAME 💅

okay bestie, welcome to rvt_recv_cq(9) from the Kernel API Manual — this one is literally here to add a new entry to completion queue by receive queue. that’s the whole vibe. 🫶

✨ SYNOPSIS ✨

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

🎀 ARGUMENTS 🎀

• qp — receive queue. yes ma’am, that’s the queue. 🧚
• wc — work completion entry to add. the little entry bestie we’re adding. ✨
• solicited — true if entry is solicited. that’s it, that’s the flag. 💅

🦋 DESCRIPTION 🦋

so this is a wrapper function for the rvt_enter_cq function call by receive queue. iconic little middleman behavior, honestly. 💖

if rvt_cq_enter returns false, that means the cq is full and the qp is put into error state. 😭 not the cute kind of plot twist.

bestie, pay attention: false from rvt_cq_enter means cq full → qp goes into error state. no cap. 💀
