irdma_reg_user_mr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 irdma_reg_user_mr — like, the Kernel API Manual, bestie 🎀

okay so real talk, this is irdma_reg_user_mr from the irdma(9) kernel API manual — she's the one who registers a user memory region, and honestly? icon behavior. no notes. ✨

✨ NAME ✨

irdma_reg_user_mr — register a user memory region</p> 💖

like literally that's her whole job. that's the gig. she registers user memory regions and she does it slayfully. 🦋

🌸 SYNOPSIS 🌸

struct ib_mr * irdma_reg_user_mr (struct ib_pd *pd , u64 start , u64 len
, u64 virt , int access , struct ib_dmah *dmah , struct ib_udata *udata
);

so she takes a bunch of things and gives you back a struct ib_mr *, which is giving main character energy ngl. 👑

🫶 ARGUMENTS 🫶

okay bestie, let's do the vibe check on every single one of these, no skips, we don't skip here:

  • pd — ptr of pd. that's it, that's the whole description. she's a pointer to a pd, and she said what she said. 💀
  • start — virtual start address. like where the vibes begin. 📍
  • len — length of mr. how long the mr is. be so fr rn, it's the length. 📏
  • virt — virtual address. yes, another one. she's virtual, she's an address, she's that girl. 🧚
  • access — access of mr. the access situation. for the mr. 🔑
  • dmah — dma handle. a handle. for the dma. iconic. 🎀
  • udata — user data. the user's data. periodt. 💅
ngl the original is a little reserved with the descriptions, and I'm not about to invent lore that isn't there — so what you see is what you get. those are the facts, bestie. 🍓

🌈 SEE ALSO 🌈

okay this is the part where she lists, like, everyone she knows. this is her whole group chat. her whole rosters. no cap, we're listing all of them — every single (9) — because she said "these are my people" and we respect that. 💜

first up, the kernel file she lives in:

  • ./drivers/infiniband/hw/irdma/verbs.c

and now, the entourage ✨:

like… the way she knows EVERYONE?? queen behavior fr fr 👑🔥

also lowkey the _irdma_destroy_qp(9) with the leading underscore is NOT a typo, bestie — she's a different function from irdma_destroy_qp(9), they're both in the list, do not merge them, do not "fix" the underscore, I am begging 🙈

and that's the page!! mwah 💋 she lives over in ./drivers/infiniband/hw/irdma, and this lil slice of manual is dated October 2026 — so mark your calendars and stan responsibly. 🦋🌸💖
