e1000_lower_ee_clk(9)

📦 version 7.3.1, in nixpkgs unstable

💖 e1000_lower_ee_clk(9) 💖

okay so real talk, bestie — we're in the Kernel API Manual today (yes, that manual, the (9) one, kernel-internals territory, very main character of us) and the function we're fangirling over is literally called e1000_lower_ee_clk. iconic name. no notes.

✨ NAME ✨

e1000_lower_ee_clk — lowers the EEPROM's clock input. that's it, that's the whole job, and honestly? she's slaying the one-task-at-a-time lifestyle 💅

🌸 SYNOPSIS 🌸

void e1000_lower_ee_clk (struct e1000_hw *hw , u32 *eecd );

look at her. returns void, takes two pointers, zero drama. goat behaviour 🐐

🎀 ARGUMENTS 🎀

  • hw — the struct holding all the variables that the shared code needs to poke at. think of it as the communal group chat where everybody drops the state they need 🫶
  • eecd — the current value of EECD. she gets handed in as a pointer, so yeah, this is the "i'm looking at you and i might touch you" kind of argument 👀

🦋 SEE ALSO 🦋

first up, the source of truth herself:

  • Kernel file ./drivers/net/ethernet/intel/e1000/e1000_hw.c

and now the whole extended friend group, in order, no one left out because we don't do that here 💜

lowkey obsessed with how e1000_raise_ee_clk(9) and e1000_lower_ee_clk(9) are both in here. opposites, both iconic, clock go up, clock go down. balance. 🌈

okay that's the whole page, bestie, and yes you read all 78 of those references, i'm so proud of you 😭💖 this little writeup came from ./drivers/net/ethernet/intel/e... dated October 2026 — go drink some water, you've earned it 🍓✨
