irdma_setup_virt_qp(9)

💅 irdma_setup_virt_qp(9) — the Kernel API Manual one, bestie

okay so real talk, this is a page from the Kernel API Manual, and it's about irdma_setup_virt_qp. It's short. It's sweet. It does one (1) thing and honestly? Respect. ✨

🌸 NAME 🌸

irdma_setup_virt_qp — setup for allocation of virtual qp 🦋

🎀 SYNOPSIS 🎀

void irdma_setup_virt_qp (struct irdma_device *iwdev , struct irdma_qp
*iwqp , struct irdma_qp_init_info *init_info );

no cap, that's the whole signature. void return, three args, zero drama. 💅

💖 ARGUMENTS 💖

• iwdev — the irdma device. it's giving "the whole personality of the hardware." 👑
• iwqp — qp ptr. yes, a pointer to the qp. iconic, brief, exactly what it says. ⭐
• init_info — initialize info to return. so this one's the output-ish one, it's where the info goes on the way back out. 🫶

🌈 SEE ALSO 🌈

first off, the kernel file lives at ./drivers/infiniband/hw/irdma/verbs.c — that's the home base, go say hi. 🏠

and then the friend group. it's a big friend group. like huge. grab a snack 🍓:

like I said. big friend group. iykyk. 🧚

no warnings, no exit statuses, no environment variables on this one — it's literally just "here's the device, here's the qp, here's where the init info goes." clean. minimal. ate. 🔥

and that's the page, bestie, that's the whole thing 💜 — sourced from ./drivers/infiniband/hw/irdma, dated October 2026, and yes the header says irdma_setup_virt_qp(9) all three times because the manpage gods love a callback. 🎀✨🌸
