i40e_aq_update_nvm(9)
π i40e_aq_update_nvm β the kernel API manual, bestie edition β¨
Okay so this one's from the Kernel API Manual, section 9 (that's the kernel-dev section, iykyk), and the star of the show is i40e_aq_update_nvm. Buckle up π
πΈ NAME πΈ
i40e_aq_update_nvm β and honestly? The original page justβ¦ leaves the description empty after the dash. Nothing. Nada. A little mysterious, a little iconic π (the DESCRIPTION section below is where the actual tea is spilled, don't worry).
β¨ SYNOPSIS β¨
int i40e_aq_update_nvm (struct i40e_hw *hw , u8 module_pointer , u32
offset , u16 length , void *data , bool last_command , u8
preservation_flags , struct i40e_asq_cmd_details *cmd_details );
That's the whole signature, copied character for character β no editing, no vibes-based fixes π
π¦ ARGUMENTS π¦
Eight of them. All of them matter. Let's go π₯
hwβ pointer to thehwstruct. Your main character struct, fr fr π«Άmodule_pointerβ module pointer location in words from the NVM beginning. Note the units bestie: words, not bytes, okay? πoffsetβ byte offset from the module beginning.lengthβ length of the section to be written (in bytes from theoffset).dataβ command buffer (size [bytes] =length). So likeβ¦ size it right or it's giving chaos πlast_commandβ tells if this is the last command in a series. Are we wrapping up or nah πpreservation_flagsβ Preservation mode flags.cmd_detailsβ pointer to command details structure orNULL.NULLis a valid answer here, no cap π
π DESCRIPTION π
Update the NVM using the admin queue commands.
That's it. That's the whole description. Short, sweet, ate and left no crumbs π The whole point of this function is to push NVM updates through the admin queue commands β that's the vibe check it has to pass β
π§ SEE ALSO π§
First up, the kernel file itself, bestie β go read the source, it's literally right there:

That's the whole group chat, no one left on read π«Ά
Heads up bestie: the original page doesn't document a return value, error codes, or any caveats β so neither do I. Don't invent lore where there isn't any π
Okay that's the page!! Big shoutout to the source, ./drivers/net/ethernet/intel/i40e, and this little beauty is dated October 2026 π Go update some NVM, you absolute icon ππ
