💅 i40e_read_nvm_word — nvm word reading, but make it iconic

So bestie, we're in the Kernel API Manual today, and the function we're stanning is i40e_read_nvm_word. It reads an nvm word and, lowkey, acquires the lock if it needs to. Period.

✨ NAME ✨

i40e_read_nvm_word — reads nvm word and acquires the lock if it's necessary 🎀

🦋 SYNOPSIS 🦋

int i40e_read_nvm_word (struct i40e_hw *hw , u16 offset , u16 *data );

That's it. That's the whole flex. 💅

🌸 ARGUMENTS 🌸

  • hw — pointer to the HW structure. like, the whole hardware situation, hand it over. 🫶
  • offset — offset of the Shadow RAM word to read. Valid range is 0x000000 – 0x001FFF, no cap. go outside that and you're on your own bestie 😭
  • data — the word read from the Shadow RAM. this is where the answer lands. the main character, truly. 👑

💖 DESCRIPTION 💖

Reads one 16 bit word from the Shadow RAM. Literally one word. Sixteen bits. Not more, not less. It's giving precision. ✨

ngl, that's the entire description — even the manpage said "that's it" and moved on. we respect the brevity. 💀

🔥 SEE ALSO 🔥

Kernel file ./drivers/net/ethernet/intel/i40e/i40e_nvm.c — go read the source, iykyk 🧚

Then the whole friend group, in order, because the manpage lists them all and we are not skipping anyone:

Every single one. ate and left no crumbs. 🌈

Okay that's the page!! 🎀 It lives in ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's the i40e_read_nvm_word(9) page from the Kernel API Manual — and yes, that's literally the whole sign-off, we're done here bestie. 💜💖✨
