irdma_map_mr_sg(9)

💅 irdma_map_mr_sg(9) — like, the kernel API manual one, bestie

okay so this is irdma_map_mr_sg, bestie — it lives in the Kernel API Manual (section 9, kernel girlies know) and it's basically the function that does the map of sg list for fmr ✨ that's the whole name-and-purpose moment, no notes.

---

🌸 SYNOPSIS 🌸

int irdma_map_mr_sg (struct ib_mr *ibmr , struct scatterlist *sg , int
sg_nents , unsigned int *sg_offset );

that's it. that's the signature. it returns an int, she's giving very much "i return an int and i know it" 💅

---

🎀 ARGUMENTS 🎀

four things, all of them important, let's go:

• ibmr — the ib mem, and you're gonna use it to access the iwarp mr pointer 🫶
• sg — the scatter gather list, iconic, we love her
• sg_nents — the number of sg pages, lowkey just a count, don't overthink
• sg_offset — the scatter gather list for fmr 🦋

fr fr bestie, that's all the page says about them — don't come for me asking for more details, i'm just the messenger 😭

so first off, there's a kernel file involved: ./drivers/infiniband/hw/irdma/verbs.c — that's the address, that's where she lives 🏡
