pvrdma_modify_qp(9)

📦 version 7.3.1, in nixpkgs unstable

💅 pvrdma_modify_qp(9) — like, the Kernel API Manual, bestie 🎀

okay so real talk, we're in the Kernel API Manual today and the main character is pvrdma_modify_qp. yes it's a 9. yes that means kernel-level. we stay unbothered and we stay in the kernel ✨

🌸 NAME 🌸

pvrdma_modify_qp — modify queue pair attributes. that's it, that's the whole vibe. you're changing up the attributes on a queue pair, lowkey glow-up energy ✨💅

🦋 SYNOPSIS 🦋

int pvrdma_modify_qp (struct ib_qp *ibqp , struct ib_qp_attr *attr , int
attr_mask , struct ib_udata *udata );

it's giving "returns an int" and takes four things. copy it exactly, no cap, the spacing is part of the aesthetic 🫶

👑 ARGUMENTS 👑

  • ibqp — the queue pair. the actual QP we're messing with. she's the main character here 💖
  • attr — the new queue pair's attributes. like, what the QP is gonna look like after the glow-up 🌈
  • attr_mask — attributes mask. tells everyone which attributes we're actually touching, iykyk 🎀
  • udata — user data. the user's little contribution to the situation 🍓

🔥 DESCRIPTION 🔥

okay so here's the tea: it returns 0 on success. otherwise it returns an errno. that's literally the whole description, and honestly? iconic. short and confident. she said what she said 💀

so like, vibe check: 0 = slay, you ate. anything else = an errno, and you should probably read it and go "oh 😭" and deal with it accordingly.

💜 SEE ALSO 💜

first up, the actual kernel file where the magic lives — go read it if you're nosy (affectionate):

./drivers/infiniband/hw/vmw_pvrdma/pvrdma_qp.c

and then the whole friend group of related calls, all in one place:

like create, destroy, send, recv, query… the full squad fr fr 🫶

kisses bestie, mwah 💋 this lil page comes from ./drivers/infiniband/hw/vmw_pv... and it's dated October 2026, so yeah, it's giving future-core, and the page name is still pvrdma_modify_qp(9) in case you forgot already 💖✨🌸
