📦 version 7.3.1, in nixpkgs unstable

💅 nfp_cpp_explicit_set_signal — the kernel API manual, bestie edition 💅

okay so you found your way into nfp_cpp_explicit_set_signal(9), the Kernel API Manual page, and honestly? iconic of you. this is the function that sets the signal fields for explicit. that's it, that's the whole name. let's get into it ✨

🎀 NAME 🎀

nfp_cpp_explicit_set_signal — Set signal fields for explicit</p>

like, it literally does what it says on the tin, no plot twist 💖

🦋 SYNOPSIS 🦋

int nfp_cpp_explicit_set_signal (struct nfp_cpp_explicit *expl , u8 signal_master , u8 signal_ref );

that's the whole vibe check — takes an explicit handle and two u8s, hands you back an int. short and sweet, main character energy fr fr 🌸

✨ ARGUMENTS ✨

  • expl — the Explicit handle 💫 your golden ticket, your little pointer to the explicit thing you're working with.
  • signal_master — the CPP Signal Master</> field. a u8, bestie, so keep it in range 👑
  • signal_ref — the CPP Signal Ref</> field. also a u8. two little signal fields, one very slay function 🎀

🔥 RETURN 🔥

0, or -ERRNO — so like, zero means we ate, and anything negative means the kernel is telling you something went sideways 😭 always check your return values, i'm begging 🫶

lowkey reminder bestie: this is kernel API territory, so read the actual source before you go poking at hardware. ./drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c is right there 💀

that's the page!! brought to you by ./drivers/net/ethernet/netrono... and dated October 2026 — and yes, the title at both the top and the bottom is nfp_cpp_explicit_set_signal(9), slay 💅🎀🦋
