i40e_vsi_request_irq_msix(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_vsi_request_irq_msix(9) — the Kernel API Manual, but make it slay ✨

okay so bestie. welcome to the Kernel API Manual entry for i40e_vsi_request_irq_msix(9) and honestly? this one is a little baddie. it's short, it's sweet, it's literally the moment your network card's interrupts get their whole life together. let's get into it 🎀

✨ NAME ✨

i40e_vsi_request_irq_msix — Initialize MSI-X interrupts 🦋

like, that's the whole vibe. that's the job. she initializes, she MSI-X's, she interrupts. iconic behavior only 👑

🌸 SYNOPSIS 🌸

int i40e_vsi_request_irq_msix (struct i40e_vsi *vsi , char *basename );

so it hands back an int (iykyk — check that return value, bestie, don't just ignore it 🙈) and it takes exactly two things: a struct i40e_vsi * and a char *. that's it. that's the whole guest list 💅

🎀 ARGUMENTS 🎀

  • vsi — the VSI being configured 💖 so like, the actual virtual station interface that's getting its glow-up in this call. she's the main character here, fr fr.
  • basename — the name for the vector ⭐ literally just the name label for the vector. that's it. that's the whole descriptor. no cap.

🧚 DESCRIPTION 🧚

okay so here's the tea, and it's genuinely a short one: this function allocates MSI-X vectors and requests interrupts from the kernel. that's the entire description. she allocates, then she asks the kernel very politely for interrupts, and the kernel (hopefully) says yes 🫶

no extra lore, no secret side quests — that's literally all the manual gives us, and we are NOT out here inventing behavior, bestie. facts only 🔥

👑 SEE ALSO 👑

the source of truth herself lives right here in the kernel file 📁

  • Kernel file ./drivers/net/ethernet/intel/i40e/i40e_main.c

and now, bestie, brace yourself — this is the friend group. the whole i40e extended universe pulled up to the function party 🌈💀 every single one of them, no gatekeeping:

ok bestie real talk: that's the whole reference list, every last one, and I did NOT skip a single one because we don't do that here 💅 respect the friend group.

🍓 the cute lil sign-off 🍓

and that's the page!! 💖 sourced straight from ./drivers/net/ethernet/intel/i40e, dated October 2026, and yes — the version tag is literally just i40e_vsi_request_irq_msix(9) again, because this manual page is its own brand 😭👑 go forth and request those interrupts, bestie. slay. periodt. 🦋✨
