irdma_uk_post_receive(9)

💌 irdma_uk_post_receive(9) 💌

okay so bestie, welcome to the kernel API manual for irdma_uk_post_receive — the little function whose entire personality is "post receive wqe" 🎀 and yes, we're gonna get into it.

No cap, this page lives in the Kernel API Manual, and the star of the show is a function called irdma_uk_post_receive. She's giving tiny-but-essential energy, and honestly? iconic.

---

✨ SYNOPSIS ✨

int irdma_uk_post_receive (struct irdma_qp_uk *qp , struct
       irdma_post_rq_info *info );

the way that signature just sits there with two structs and an int return 🦋 it's literally the whole vibe. so, so clean.

---

💅 ARGUMENTS 💅

• qp — hw qp ptr 💖 like, a pointer to the hardware queue pair. that's her whole job description, and she ate.
• info — post rq information 🌸 all the info you need to actually post the receive queue entry. main character of the arguments, tbh.

ngl these two are a package deal — a hw qp ptr and the post rq information. don't be weird about it, just pass them both. 🫶
