💖 igc_update_nvm_checksum_i225(9) 💖

okay so bestie, we're in the Kernel API Manual today and the star of the show is igc_update_nvm_checksum_i225 — yes that's a whole mouthful, no I will not be shortening it, it's iconic and it knows it 💅

✨ NAME ✨

igc_update_nvm_checksum_i225 — Update EEPROM checksum 🎀

like literally what it says on the tin. it updates the EEPROM checksum. that's the whole vibe.

🦋 SYNOPSIS 🦋

s32 igc_update_nvm_checksum_i225 (struct igc_hw *hw );

🌸 ARGUMENTS 🌸

  • hw — pointer to the struct igc_hw structure 🫶 literally just a pointer to the HW structure, that's it, that's the whole argument

💜 DESCRIPTION 💜

okay so here's what actually goes down 👑

It updates the EEPROM checksum by reading/adding each word of the EEPROM up to the checksum. every word. one by one. the dedication?? unmatched fr fr 😭

Then it calculates the EEPROM checksum and writes that value to the EEPROM. math moment ✨

Next — and this is the final boss step — it commits the EEPROM data onto the Flash 🌈 so like, the data actually lands. no cap.

not me describing a checksum routine like it's a whole plot arc 😭 but honestly the way it's giving main character energy
