hfi1_make_uc_req(9)

🎀 NAME 🎀

bestie, welcome to hfi1_make_uc_req(9) from the Kernel API Manual 💖 — the function that constructs a request packet (SEND, RDMA write). No cap, that's the whole name vibe. ✨

🌸 SYNOPSIS 🌸

int hfi1_make_uc_req (struct rvt_qp *qp , struct hfi1_pkt_state *ps );

🦋 ARGUMENTS 🦋

• qp — a pointer to the QP 💅 like, the queue pair in question, bestie.
• ps — the current packet state 🎀 the packet's current situation, basically.

✨ DESCRIPTION ✨

Okay so first thing: assume s_lock is held. 🔒 That's the vibe check — don't come through without it, fr fr.

Then the function does its construct-a-request-packet moment. If it constructed it, return 1; otherwise, return 0. Periodt. 💅

Heads up: the s_lock-is-held assumption is literally in the original page — keep that energy. 🫶
