e1000_write_nvm_eewr_82571(9)

📦 version 7.3.1, in nixpkgs unstable

💅 e1000_write_nvm_eewr_82571(9) — like, the Kernel API Manual page bestie 🎀

okay so picture this: it's a Kernel API Manual page, the star of the show is e1000_write_nvm_eewr_82571, and honestly? it's giving "tiny function, big responsibility." she writes stuff to EEPROM. for 82573 silicon. that's the whole vibe. periodt. ✨

🌸 NAME 🌸

e1000_write_nvm_eewr_82571 — write to EEPROM for 82573 silicon 💖

like yes, that's literally it, that's her whole job description and she's slaying it.

🦋 SYNOPSIS 🦋

s32 e1000_write_nvm_eewr_82571 (struct e1000_hw *hw , u16 offset , u16
words , u16 *data );

she takes four things, returns an s32, and she's not sorry about it. 💅

✨ ARGUMENTS ✨

okay bestie, let's meet the cast 🫶

  • hw — pointer to the HW structure. the main character. everything happens through her.
  • offset — offset within the EEPROM to be written to. literally where in the EEPROM we're putting the thing 📍
  • words — number of words to write. how many of them. the count. the amount. 🧚
  • data — 16 bit word(s) to be written to the EEPROM. the actual payload, the content, the moment 💫

🔥 DESCRIPTION 🔥

so here's the tea ☕ — first she's checking for invalid values, because we do not write garbage into EEPROM, that's not the energy we're bringing. then she polls the EEPROM to make sure the previous command has completed before trying to write the next word, and after the write she polls again for completion. two vibe checks, one function. consistent queen. 👑

⚠️ important warning, no cap: if e1000e_update_nvm_checksum is not called after this function, the EEPROM will most likely contain an invalid checksum. like, it will be a mess. so please call it. do it for her. 😭

🌈 SEE ALSO 🌈

the kernel file that started it all:

Kernel file ./drivers/net/ethernet/intel/e1000e/82571.c

and now, the full friend group — every single one of them, in order, nothing skipped, we respect the roster 🫡

🎀 and that's the page, bestie 🎀

one last lil sign-off: this absolute icon of a manpage is dated October 2026, it lives under the source path ./drivers/net/ethernet/intel/e... (yes that's how it's printed, truncated and all, we don't edit the source line, that's the rule 💀), and it answers to the name e1000_write_nvm_eewr_82571(9). go forth, write your EEPROM words, poll for completion, and please update that checksum. ily. bye. 🦋💜
