🌸 irdma_ib_register_device(9) — the registration glow-up 💅

okay so this is a page out of the Kernel API Manual, and it's about irdma_ib_register_device — like, the literal moment your irdma device gets introduced to the IB core. it's giving "first day at a new school but everyone's a kernel subsystem." bestie, it's short, it's sweet, let's get into it ✨

🦋 NAME

irdma_ib_register_device — register irdma device to IB core

no cap, that's the whole thing. the function name lowkey tells the story: you've got an irdma device, IB core hasn't met it yet, and this is the handshake 🫶

⭐ SYNOPSIS

int irdma_ib_register_device (struct irdma_device *iwdev );

it returns an int (yes, there's a return value, check it, don't just vibe past it 🙈) and it takes exactly one argument. that's it. that's the signature.

🎀 ARGUMENTS

  • iwdev — the irdma device. that's the one you're introducing to the IB core. it's the main character here 👑

💜 SEE ALSO

okay so this list is long — like, unreasonably long, but we don't skip pages in this house 💅 everything lives in the kernel file ./drivers/infiniband/hw/irdma/verbs.c, and here's the whole squad:

like I said. a whole friend group 🧚 and yeah, _irdma_destroy_qp(9) and __irdma_poll_cq(9) really do have those leading underscores — that's not a typo, that's just how they're built 💀

and that's the page!! go register that device, bestie, IB core is waiting 💖
