nfp_net_aux_irq_request(9)

📦 version 7.3.1, in nixpkgs unstable

💅 nfp_net_aux_irq_request — from the Kernel API Manual ✨

okay bestie, so this page is literally titled nfp_net_aux_irq_request and it lives in the Kernel API Manual, and it is exactly what it says on the tin. 🎀

✨ NAME ✨

nfp_net_aux_irq_request — request an auxiliary interrupt (LSC or EXN). that's it, that's the whole vibe. auxiliary. side-quest interrupts. main character interrupts get their own function, these ones are the besties. 🦋

🌸 SYNOPSIS 🌸

int nfp_net_aux_irq_request (struct nfp_net *nn , u32 ctrl_offset ,
const char *format , char *name , size_t name_sz , unsigned int
vector_idx , irq_handler_t handler );

like, look at that signature. seven whole arguments. she's thorough. 💅

👑 ARGUMENTS 👑

  • nn — the NFP Network structure. your whole netdev situation, the main character of this function ngl. 🌈
  • ctrl_offset — the Control BAR offset where the IRQ configuration should be written. yes, that BAR. the control one. write the config there, don't ask questions. ✨
  • format — a printf-style format to construct the interrupt name. so the name gets built with printf energy, iconic behaviour fr. 🎀
  • name — a pointer to allocated space for the interrupt name. you bring the buffer, the function brings the string. 🫶
  • name_sz — the size of the space for the interrupt name. bestie please make it big enough, that's the whole point of passing it. 😭
  • vector_idx — the index of the MSI-X vector used for this interrupt. which vector? this vector. number vector_idx. slay. 🔥
  • handler — the IRQ handler to register for this interrupt. the callback. the one who actually does stuff when the interrupt shows up. 👑

💜 SEE ALSO 💜

okay so first up, the kernel file itself:

Kernel file ./drivers/net/ethernet/netronome/nfp/nfp_net_common.c

and then the whole friend group, no cap, every single one of them:

lowkey the read-the-whole-list challenge, but it's mandatory, not optional. iykyk 💀

🎀 and that's the page!! source/version line said ./drivers/net/ethernet/netrono... and the date was October 2026, so like… future manpage, obsessed. stay hydrated, go request your auxiliary interrupts responsibly, mwah 💖✨🦋🌸💅
