💅 irdma_hw_alloc_mw(9) — the hw memory window maker 💅

okay so bestie, welcome to the Kernel API Manual corner of the group chat 🫶. This one's a lil function called irdma_hw_alloc_mw and honestly? It's giving "small but mighty" energy. Its whole ~thing~ is creating the hw memory window, no cap ✨.

✨ NAME ✨

irdma_hw_alloc_mw — create the hw memory window 🎀

Like, that's it, that's the job. She makes the hw memory window. iconic behavior only.

---

🦋 SYNOPSIS 🦋

int irdma_hw_alloc_mw (struct irdma_device *iwdev , struct irdma_mr
*iwmr );

Returns an int, takes two pointers, lives her truth. Periodt 💅

---

🌸 ARGUMENTS 🌸

• iwdev — the irdma device 👑. That's the main character right there, the device you're working with.
• iwmr — pointer to memory window info 🎀. This is the memory-window info she's gonna be working off of.
