rvt_copy_sge(9)

okay so bestie, welcome to rvt_copy_sge(9) from the Kernel API Manual 💅 this one is short, sweet, and very “copy data to SGE memory” — no cap.

✨ NAME ✨

rvt_copy_sge — copy data to SGE memory 💖

🌸 SYNOPSIS 🌸

Here’s the signature, exactly as it appears, because we do not mess with code, periodt:

void rvt_copy_sge (struct rvt_qp *qp , struct rvt_sge_state *ss , void *data , u32 length , bool release , bool copy_last );

💖 ARGUMENTS 💖

okay bestie, here’s the cast of characters — every single one matters, no skips:

• qp — associated QP 🦋
• ss — the SGE state ✨
• data — the data to copy 🎀
• length — the length of the data 📏
• release — boolean to release MR 🫶
• copy_last — do a separate copy of the last 8 bytes 💅
