e1000_updat...checksum_spt(9)

📦 version 7.3.1, in nixpkgs unstable

💖 e1000_update_nvm_checksum_spt 💖

okay so bestie, we're in the Kernel API Manual today, and this one is a whole function — e1000_update_nvm_checksum_spt. Say it with me. It's giving "I fix the checksum in your NVM and I do it with flair." ✨

🎀 NAME 🎀

e1000_update_nvm_checksum_spt — literally just: Update the checksum for NVM. That's the whole vibe. 🦋

✨ SYNOPSIS ✨

s32 e1000_update_nvm_checksum_spt (struct e1000_hw *hw );

yes the trailing space before the paren is canon, don't @ me 💅

🌸 ARGUMENTS 🌸

  • hw — pointer to the HW structure. that's it. that's the whole argument list. she's low maintenance. 🫶

💜 DESCRIPTION 💜

So here's the tea, bestie. 🍵

The NVM checksum gets updated by calling the generic update_nvm_checksum, which writes the checksum to the shadow ram. Iconic. ✨

Then the changes in the shadow ram get committed to the EEPROM — and the way she does it is so main character: she processes each bank at a time, checking for the modified bit and writing only the pending changes. no cap, that's the whole flex. 🔥

After a successful commit, the shadow ram is cleared and is all ready for future writes. fresh start, clean slate, new era. 🌈
