📦 version 7.3.1, in nixpkgs unstable

💅 i40e_nvmupd_nvm_write(9) — like, the NVM writer bestie

okay so this is a page from the Kernel API Manual, and it's all about i40e_nvmupd_nvm_write — the function that writes NVM. yes bestie, actual NVM, the persistent stuff, so pay attention 💖

✨ NAME ✨

i40e_nvmupd_nvm_write — Write NVM 🖊️✨

🦋 SYNOPSIS 🦋

int i40e_nvmupd_nvm_write (struct i40e_hw *hw , struct i40e_nvm_access
*cmd , u8 *bytes , int *perrno );

it's giving "four args, one job, zero chill" 😌

🎀 ARGUMENTS 🎀

  • hw — pointer to hardware structure. like, the actual NIC's whole personality lives in here 🫶
  • cmd — pointer to nvm update command buffer. this is the little envelope carrying what you actually wanna do 📬
  • bytes — pointer to the data buffer. the payload, the good stuff, the main character 💅
  • perrno — pointer to return error code. if something goes sideways, the tea gets reported back through here 🙈

🌸 DESCRIPTION 🌸

so basically: module, offset, data_size and data are all chillin' inside the cmd structure. that's the whole vibe — the command struct is where the intel lives, and this function goes and reads it 👑

ngl, that's literally the entire description on the original page — no extra lore, no secret bonus paragraphs. it's a short one and it ate ⭐

💜 SEE ALSO 💜

the kernel file in question, for when you want to go straight to the source (iconic behaviour):

  • Kernel file ./drivers/net/ethernet/intel/i40e/i40e_nvm.c

and now the full friend group — literally every one of these, no cap 🫶:

thirty whole references, like… the i40e NVM family is huge and we love her for it 🌈

that's the whole page, bestie — short, sweet, and every single detail intact. stay hydrated, read your checksums, and remember: writing NVM is forever, so maybe double-check that cmd struct first 😭💖

this lil slice of manual comes from ./drivers/net/ethernet/intel/i40e, dated October 2026 — mwah, sending love from the kernel tree 🎀✨
