πŸ’– igb_validat..._with_offset(9) πŸ’–

okay so first things first, bestie β€” welcome to the igb_validat..._with_offset(9) page, straight outta the Kernel API Manual. yes the title is truncated, no i don't know why, and yes we're gonna get through it together. grab a strawberry πŸ“


✨ NAME ✨

igb_validate_nvm_checksum_with_offset β€” Validate EEPROM checksum, periodt. that's the whole vibe πŸ’…


🌸 SYNOPSIS 🌸

s32 igb_validate_nvm_checksum_with_offset (struct e1000_hw *hw , u16
offset );

like, look at her. iconic signature. πŸŽ€


πŸ¦‹ ARGUMENTS πŸ¦‹

  • hw β€” pointer to the HW structure. yes she needs the hardware struct, she's not doing this alone, main character needs her supporting cast 🫢
  • offset β€” offset in words of the checksum protected region. words, not bytes, iykyk πŸ“

πŸ”₯ DESCRIPTION πŸ”₯

okay so here's the tea β˜• β€” this function calculates the EEPROM checksum by literally reading and adding each word of the EEPROM, one by one, no skipping, no shortcuts. then it verifies that the sum of the EEPROM is equal to 0xBABA.

that's it. that's the whole flex. 0xBABA is the magic number and honestly? she ate. πŸ’€βœ¨
