📦 version 7.3.1, in nixpkgs unstable

🎀 irdma_uk_qp_init(9) — like, the Kernel API Manual entry you actually wanna read 🎀

okay bestie, gather round, because we're diving into irdma_uk_qp_init — yes that's the whole name, yes it's a mouthful, no we're not changing it 💅 this one lives in the Kernel API Manual, so you know it's the real deal.

✨ NAME ✨

irdma_uk_qp_init — initialize shared qp 🫶

🦋 SYNOPSIS 🦋

int irdma_uk_qp_init (struct irdma_qp_uk *qp , struct
irdma_qp_uk_init_info *info );

literally the entire vibe, right there 👑

🌸 ARGUMENTS 🌸

  • qp — the hw qp, and listen: it's the same one for both user and kernel mode, no cap 🫶
  • info — the qp initialization info, aka the little care package of setup deets 💌

💖 DESCRIPTION 💖

so what does it actually do? it initializes the vars used in both user and kernel mode — one function, two worlds, main character energy fr fr ✨

here's the tea on memory, because this part is giving math class but it's important:

  • the size of the wqe depends on the numbers of max. fragements allowed 📐
  • then size of wqe × the number of wqes should be the amount of memory allocated for sq and rq 💀

that's it, that's the whole thing — but like, get that multiplication right, okay? it's not a suggestion, it's the amount of memory. periodt. 🔥
