hfi1_verbs_send(9)

✨ NAME ✨

okay bestie, meet hfi1_verbs_send(9) from the Kernel API Manual — its whole job is: send a packet. That's the vibe. 💌

🌸 SYNOPSIS 🌸

int hfi1_verbs_send (struct rvt_qp *qp , struct hfi1_pkt_state *ps );

Lowkey iconic signature, no notes. 💅

🎀 ARGUMENTS 🎀

• qp — the QP to send on. main character QP fr.
• ps — the state of the packet to send. all the packet lore lives here.

🦋 DESCRIPTION 🦋

So here's the tea: if the packet is sent or queued OK, this returns zero. Zero = good vibes. ✨

Otherwise — not OK — it returns non-zero and clears RVT_S_BUSY in qp->s_flags. That's the whole contract, no cap. 💀
