e1000_request_irq(9)

📦 version 7.3.1, in nixpkgs unstable

💖 e1000_request_irq(9) 💖

okay so first things first, bestie: we're in the Kernel API Manual today, and this page is e1000_request_irq(9) — the little function that gets your NIC's interrupts actually, you know, interrupting. it's giving "networking plumbing but make it cute." 🦋

✨ NAME ✨

e1000_request_irq — initialize interrupts

like, the whole vibe is: wake the hardware up so it can poke the kernel when packets show up. periodt. 💅

🎀 SYNOPSIS 🎀

int e1000_request_irq (struct e1000_adapter *adapter );

that's the whole call. one argument, returns an int, no cap. 🫶

🌸 ARGUMENTS 🌸

  • adapter — board private structure. that's it, that's the whole description. it's the adapter struct that holds all the board-private goodies this function needs to go do its thing. she's the main character here, honestly. 👑

🔥 DESCRIPTION 🔥

okay so what does this actually do? e1000_request_irq attempts to configure interrupts using the best available capabilities of the hardware and kernel. 🧚

the way that works: it doesn't just pick one thing and commit — it looks at what your hardware can do and what your kernel can do, and goes with the best of the bunch. iconic behavior, lowkey. it's "attempts," too, so like… it might not succeed, and that's why the return type is int. pays to check. 🙈

🌈 SEE ALSO 🌈

bestie, buckle up, because this list is long and every single one of these is a real one. the kernel file it lives in:

  • Kernel file ./drivers/net/ethernet/intel/e1000e/netdev.c

and now the whole group chat — 89 functions, all (9):

like I said. long. but every one of them matters, so don't skip. iykyk. 💀💜

ngl, the descriptions on this page are short — that's just what the page says, bestie. don't go reading behavior into it that isn't written down. 😭

okay that's the page!! 🍓 tiny little sign-off before you go: this one's sourced from ./drivers/net/ethernet/intel/e... (yes it's abbreviated on the page, that's how they gave it to us 💅) and it's dated October 2026. and it's e1000_request_irq(9) again, one more time, for the people in the back. slay, go configure those interrupts. ⭐🎀
