ixgbe_update_itr(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ixgbe_update_itr(9) — from the Kernel API Manual, bestie 🎀

okay so this is a page straight out of the Kernel API Manual and it's all about ixgbe_update_itr(9). it's short, it's sweet, it's giving "small function, big job" energy. let's get into it ✨

🌸 NAME 🌸

ixgbe_update_itr — update the dynamic ITR value based on statistics

like, that's literally her whole personality. she looks at stats and updates a number. icon behavior, no cap 💅

🦋 SYNOPSIS 🦋

void ixgbe_update_itr (struct ixgbe_q_vector *q_vector , struct
       ixgbe_ring_container *ring_container );

returns nothing (void), takes two pointers, in and out. chef's kiss 🫶

🎀 ARGUMENTS 🎀

  • q_vector — the structure containing interrupt and ring information 💖
  • ring_container — the structure containing ring performance data 📊

two structs walk into a function. that's the whole plot. 🍓

🔥 DESCRIPTION 🔥

okay so what she actually does: she stores a new ITR value based on the packets and byte counts during the last interrupt. per-interrupt computation is the moment here — the advantage of doing it this way is faster updates and a more accurate ITR for the current traffic pattern. it's giving "knows what you need before you do" 💫

and the math? the constants in this function were computed based on theoretical maximum wire speed, and the thresholds were set based on testing data — plus a whole attempt to minimize response time while increasing bulk throughput. so like, she's tuned. she's calibrated. she ate. 👑

ngl the vibe here is "quietly doing extremely precise math in the background while everyone else is loud" — main character energy fr fr 🌈

👑 SEE ALSO 👑

first up, the source itself — the kernel file lives at ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c. go say hi 🫶

and then the whole extended friend group. literally everyone in the ixgbe cinematic universe shows up, and yes we're listing all of them because nobody gets left out:

like… the way she knows EVERYONE. networking queen behavior honestly 💀🌈

💌 okay that's the page!! source/version on this one is ./drivers/net/ethernet/intel/i... and it's dated October 2026 — so she's from the future (kinda) and she's still updating ITR values based on statistics. we stan. bye bestie, go read the driver 💅✨🎀
