irdma_uk_srq_init(9)

📦 version 7.3.1, in nixpkgs unstable

💖 irdma_uk_srq_init — bestie's guide to initializing a shared qp 💖

okay so this one's from the Kernel API Manual, section 9, and it's literally just... setting up your SRQ so the hardware doesn't get confused. let's go 🫶

✨ NAME ✨

irdma_uk_srq_init — initialize shared qp

(yes the NAME says "shared qp" and the function is about srq. that's what the page says, we don't question the ancestors 😭)

🌸 SYNOPSIS 🌸

int irdma_uk_srq_init (struct irdma_srq_uk *srq , struct
       irdma_srq_uk_init_info *info );

two args, returns an int. that's the whole vibe check 💅

🎀 ARGUMENTS 🎀

  • srq — the hw srq. both user and kernel mode, so it's giving main character energy for everybody 👑
  • info — the srq initialization info. all the setup deets live in here 🦋

🌈 DESCRIPTION 🌈

so basically this function initializes the vars that get used in both user and kernel mode — one function, two worlds, iconic crossover ✨

the size of the wqe depends on the number of max fragments allowed. then: size of wqe * the number of wqes = the amount of memory allocated for srq. that's the math, no cap 📐

fr fr the memory math matters — get your fragment count wrong and the alloc is wrong, and that's a bad time 💀
