igc_request_irq(9)

📦 version 7.3.1, in nixpkgs unstable

✨ igc_request_irq 💅

okay so real talk — this page is from the Kernel API Manual, and today's main character is igc_request_irq(9). she's the one who actually gets your interrupts, like, existing. 🎀

🌸 NAME 🌸

igc_request_irq — initialize interrupts ✨

🦋 SYNOPSIS 🦋

int igc_request_irq (struct igc_adapter *adapter );

💜 ARGUMENTS 💜

  • adapter — a pointer to the adapter structure. that's the whole vibe. that's the whole argument. give her the adapter and let her cook 🫶

🔥 DESCRIPTION 🔥

so what does she actually do? she attempts to configure interrupts using the best available capabilities of the hardware and kernel. 💅

like — she looks at what your hardware can do, she looks at what your kernel can do, and she goes "okay bestie, THIS is the combo we're running with." no cap. the best available ones. not the mid ones, not the leftover ones. the best. 👑

note the word attempts — she's out here trying her best, and the return value tells you how that went. the manpage does not elaborate further, and honestly? neither will I. iykyk 😌

🌈 SEE ALSO 🌈

okay this is the part where she tags her entire friend group. every single one. not me listing all of them — but also literally me listing all of them, because i would never leave one out. 💖

the kernel file this lives in:

  • ./drivers/net/ethernet/intel/igc/igc_main.c

and now the group chat, in order, nobody's getting left on read:

and that's the whole page, bestie. no crumbs. every flag-free, option-free, interrupt-having detail intact. 🧚

sign-off time 🎀 — this little masterpiece lives in ./drivers/net/ethernet/intel/igc, and it's dated October 2026. yes, the future. she's ahead of her time, periodt. 💜
