💅 i40e_write_nvm_aq — bestie's guide to the kernel API manual ✨

okay so this is i40e_write_nvm_aq(9) from the Kernel API Manual, and honestly? it's giving "tiny function, big responsibilities" energy. we're literally writing Shadow RAM here. no cap. let's get into it 🎀

🦋 SYNOPSIS

int i40e_write_nvm_aq (struct i40e_hw *hw , u8 module_pointer , u32
       offset , u16 words , void *data , bool last_command );

like, that's the whole signature. six args. she's got a lot going on but she's iconic for it 💜

✨ ARGUMENTS

  • hw — pointer to the HW structure. the main character of the whole operation, fr fr 🫶
  • module_pointer — the module pointer location, measured in words from the NVM beginning. yes, in words. not bytes. don't come for me 😭
  • offset — offset in words from module start. again: words. lowkey important that you clock that 👑
  • words — the number of words to write. it's right there in the name, bestie 💀
  • data — buffer with the words you're writing to the Shadow RAM. this is your payload, your moment, your main character data 🌟
  • last_command — tells the AdminQ that this is the last command. like the final text in the group chat before you go to sleep. big deal, ngl 🙈

🌸 DESCRIPTION

Writes a 16 bit words buffer to the Shadow RAM using the admin command. that's it, that's the vibe check. short and slay ✨

ok real talk, this one's a one-liner description on purpose — no extra lore, no secret side quests, just: 16-bit words go into Shadow RAM via the admin command. don't go inventing features, iykyk 💅

🔥 SEE ALSO

the kernel file lives at ./drivers/net/ethernet/intel/i40e/i40e_nvm.c — go read it, it's like the director's cut 🎬
