wx_write_eitr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 wx_write_eitr(9) — like, the Kernel API Manual page you actually wanna read ✨

okay bestie, welcome to the Kernel API Manual entry for wx_write_eitr(9) 🫶 this is the little function that writes an EITR register, but in a hardware-specific way. yes, hardware has opinions, and this function deals with them so you don't have to. iconic behavior honestly 💖

🌸 NAME 🌸

wx_write_eitr — write EITR register in a hardware specific way ✨

like, it writes the EITR register, but the hardware-specific way. no cap, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

void wx_write_eitr (struct wx_q_vector *q_vector );

that's it. that's the whole signature. one argument, zero drama 💅

⭐ ARGUMENTS ⭐

  • q_vector — a structure containing interrupt and ring information 🌀 like, it's the little bundle that holds both the interrupt deets and the ring deets. everything you need to know, all up in one struct, main character energy fr fr 👑

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ this function is made to be called by ethtool, and also by the driver itself, whenever it needs to update EITR registers at runtime. yes, at runtime. mid-flight. while everything's already running. highkey stressful but she handles it 💪

and the hardware-specific quirks and differences? all taken care of right here, inside this function 🛠️✨ every weird little per-hardware difference gets smoothed out so the callers don't have to think about it. it's giving "designated friend who handles the group chat logistics" honestly 🫶

ngl, this is one of those functions where the hardware quirk handling is the whole point — if you're touching it, remember that different hardware does different stuff and this is where that lives 🩷

that's the whole lineup, no skips, no cuts 💀✨

and that's the page, bestie 🎀 this one came from ./drivers/net/ethernet/wangxun... and it's dated October 2026, so like… future vibes but make it kernel 🦋 mwah, go read some more manpages, ily, periodt 💜👑
