📦 version 7.3.1, in nixpkgs unstable

e1000_read_nvm_spt(9) 💅✨

okay so bestie, welcome to the Kernel API Manual page for e1000_read_nvm_spt — yes that's the whole title, and yes it's a C function in the kernel, not a person. sit down, hydrate, let's get into it 🫶

✨ NAME ✨

e1000_read_nvm_spt — NVM access for SPT 🌸

🦋 SYNOPSIS 🦋

s32 e1000_read_nvm_spt (struct e1000_hw *hw , u16 offset , u16 words ,
u16 *data );

like, that's the whole signature. it returns an s32, and it takes four things. we about to go through all four, don't worry 💜

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. it's giving "the main character of the story", everything happens through this pointer ✨
  • offset — the offset (in bytes) of the word(s) to read. yes, in bytes, even though the stuff you're reading is counted in words. iykyk 😭
  • words — size of data to read in words. this is the "how much" number 🍓
  • data — pointer to the word(s) to read at offset. this is where the answer goes. it's giving output parameter energy 👑

💀 DESCRIPTION 💀

reads a word(s) from the NVM.

that's it. that's the desc. no cap, the manpage really said one sentence and left. respect honestly 🌈

👑 SEE ALSO 👑

first up, the actual kernel file this lives in, fr fr:

and now the iconic extended universe — every single cross-reference, bestie, all of them, i'm not skipping a one 🔥

ngl, if you're reading this page at 3am while debugging a NIC, you're doing amazing sweetie. go drink some water 🧚💖

and that's the page, bestie 🎀 — it's from the source path ./drivers/net/ethernet/intel/e..., dated October 2026, and the footer just repeats the name back at you: e1000_read_nvm_spt(9). slay, bye 👋💜
