idpf_get_reg_intr_vecs(9)

📦 version 7.3.1, in nixpkgs unstable

💅 idpf_get_reg_intr_vecs(9) — straight outta the Kernel API Manual, bestie 💅

okay so picture this: we're deep in the kernel API manual, section 9, and the main character of today's episode is idpf_get_reg_intr_vecs. no cap, she's a little function with a big job. let's get into it 🫶

✨ NAME ✨

idpf_get_reg_intr_vecs — bestie, it gets the vector queue register offset. that's the whole vibe. lowkey one line, highkey important 💖

🦋 SYNOPSIS 🦋

int idpf_get_reg_intr_vecs (struct idpf_adapter *adapter , struct
       idpf_vec_regs *reg_vals , int num_vecs );

literally right there in all its glory ✨ three args, one int coming back at you.

🎀 ARGUMENTS 🎀

  • adapter — the adapter structure, aka the girl who's gonna go get the vector chunks for us. she's the source of truth here 👑
  • reg_vals — the register offsets, and this is where we store them. like a little basket, but for offsets 🧺
  • num_vecs — how many entries the reg_vals array can actually hold. it's giving capacity check, it's giving boundaries, we respect her 💅

⭐ RETURN ⭐

returns the number of registers that got populated. so not just "did it work", it's "how many of these babies actually made it in" 🔥

🌈 SEE ALSO 🌈

first up, the kernel file location so you can go snoop for yourself: ./drivers/net/ethernet/intel/idpf/idpf_virtchnl.c 🕵️‍♀️

and now the extended friend group, because this function does NOT roll alone. not one, not two — the whole group chat:

like I said. the whole group chat. every single one of them 💀💖

bestie note: that file path and those (9) refs are literal — don't retype them from memory, copy them exactly or the kernel girlies will come for you 🙈

and that's the tea 🍵 this whole page lives in the kernel file ./drivers/net/ethernet/intel/idpf, dated October 2026, and it's filed under idpf_get_reg_intr_vecs(9). periodt. 💅✨🦋
