irdma_query_device(9)

💅 irdma_query_device — a Kernel API Manual moment (section 9, bestie)

okay so picture this: you're deep in the kernel, section 9, and there's exactly one function whose whole personality is tell me about this device. That's irdma_query_device. No cap. It's the "so… what are you?" of the RDMA world and honestly? iconic. 🫶

✨ NAME ✨

irdma_query_device — get device attributes 🌸

🦋 SYNOPSIS 🦋

int irdma_query_device (struct ib_device *ibdev , struct ib_device_attr
*props , struct ib_udata *udata );

signed, sealed, and returning an int — the vibes are immaculate, the argument list is right there 👑

🎀 ARGUMENTS 🎀

• ibdev — the device pointer, and listen, it comes from the stack. that's the whole note. that's the lore. 🧚
• props — this is the one doing the real work: the device attributes coming back out to you. it's giving "results go here" energy. ✨
• udata — user data. lowkey mysterious, highkey just sitting there being user data. 💜

💀 yes that's all of them. yes we listed them all. the way this page said "SEE ALSO" and meant see also literally everything. we ate. 🍓

and that's the page, bestie 🎀 — it lives in ./drivers/infiniband/hw/irdma, dated October 2026, and it's filed under irdma_query_device(9) in the Kernel API Manual. go query a device, you've earned it 🌈👑💖
