irdma_handle_q_mem(9)

💅 irdma_handle_q_mem — the Kernel API Manual tea ☕

okay so bestie, welcome to irdma_handle_q_mem(9) — this is a page straight out of the Kernel API Manual, and it's all about handling memory for qp and cq. yes, the whole personality is "memory management for queue pairs and completion queues." iconic honestly.

---

✨ NAME ✨

irdma_handle_q_mem — handle memory for qp and cq 🎀

---

🌸 SYNOPSIS 🌸

int irdma_handle_q_mem (struct irdma_device *iwdev , struct
       irdma_mem_reg_req *req , struct irdma_pbl *iwpbl , u8 lvl );

like, it returns an int, and it takes four things. that's it. that's the function. no cap.

---

🦋 ARGUMENTS 🦋

four args, all of them doing the absolute most:

• iwdev — the irdma device itself 🖥️ like, the whole vibe of the hardware you're working with.
• req — information for q memory management 📋 the details about how the q memory is gonna get managed.
• iwpbl — pble struct 🧱 your pbl-adjacent struct, lives here now.
• lvl — pble level mask 🎚️ a u8 mask for the pble level. mask. level. we love a masked level.

bestie that's like 80+ pages, don't try to read them all in one sitting, hydrate first 🥤

and that's the whole page! no plot twist, no hidden option, no extra env var. just vibes and a function signature. 🧚
