e1000e_read_nvm_eerd(9)

💖 e1000e_read_nvm_eerd(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little function from the e1000e driver fam and honestly she's kind of a legend. sit down, grab a strawberry 🍓, let's get into it.

🌸 NAME 🌸

e1000e_read_nvm_eerd — reads EEPROM using the EERD register 💅

like, that's literally her whole job. she reads the EEPROM. with the EERD register. iconic behavior, no notes.

---

✨ SYNOPSIS ✨

s32 e1000e_read_nvm_eerd (struct e1000_hw *hw , u16 offset , u16 words ,
       u16 *data );

look at that signature, she's giving main character energy 🫶. returns an s32, takes a struct e1000_hw *, a u16 offset, a u16 words, and a u16 *data. perfect. flawless. exactly as expected.

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 💻 — this is the hardware bestie herself, the whole vibe.
• offset — offset of word in the EEPROM to read 📍 — where in the EEPROM we're looking. yes bestie, we're going in with a map.
• words — number of words to read 🔢 — how many of them we want. greedy? maybe. valid? absolutely.
• data — word read from the EEPROM 📥 — this is where the good stuff lands. the payload. the moment.

---

🦋 DESCRIPTION 🦋

so the way that this works is — she reads a 16 bit word from the EEPROM using the EERD register ✨. that's it. that's the whole thing. no cap, she's a simple girl with a simple purpose and she absolutely ate.

sixteen bits. read. from EEPROM. via EERD. periodt 💅

ngl bestie, this page is short and sweet — but that just means there's nothing to misremember. 16 bits, EERD register, done. slay. 💀✨

and that's the tea 🫖 — page pulled from ./drivers/net/ethernet/intel/e..., dated October 2026, and yes the title at the bottom is still e1000e_read_nvm_eerd(9) because she's consistent like that 💜 🧚 bye bestie, go read some EEPROM! 🎀
