nfp_net_aux_irq_free(9)

✨ nfp_net_aux_irq_free ✨

okay bestie, welcome to the Kernel API Manual, section 9 — yes, the big-league kernel docs, and today's main character is nfp_net_aux_irq_free(9). she's a tiny function with a big job 🎀

💖 NAME 💖

nfp_net_aux_irq_free — frees an auxiliary interrupt (that's LSC or EXN, iykyk) 🦋

🌸 SYNOPSIS 🌸

void nfp_net_aux_irq_free (struct nfp_net *nn , u32 ctrl_offset ,
       unsigned int vector_idx );

like, returns nothing, takes three things, no cap. void queen behavior 💅

⭐ ARGUMENTS ⭐

• nn — the NFP Network structure. your whole network vibe lives in here ✨
• ctrl_offset — the Control BAR offset where the IRQ configuration should be written. this is literally where the write happens, so don't fumble it 🙈
• vector_idx — the index of the MSI-X vector used for this interrupt. which vector, bestie? that one 👑

🦋 SEE ALSO 🦋

the kernel file in question, for the curious girlies:

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

and the whole friend group — every single one, no skipping, we don't do that here:

fr fr, that's the entire squad — nfp_net_free(9) and nfp_net_clean(9) are the cleanup besties, and nfp_net_aux_irq_request(9) is this function's literal other half 🫶

and that's the page, bestie! 💜 source line was the truncated path ./drivers/net/ethernet/netrono... and the date on the tin is October 2026, all filed under nfp_net_aux_irq_free(9) in the Kernel API Manual. periodt. 💅🎀
