πŸ’– igb_validate_nvm_checksum_i210 πŸ’–

okay bestie, so this is a page straight out of the Kernel API Manual, section 9 β€” the whole igb_validate...hecksum_i210(9) situation. pull up a chair, we're doing EEPROM math together 🧚✨


🌸 NAME 🌸

igb_validate_nvm_checksum_i210 β€” the function that validates the EEPROM checksum, no cap πŸ’…


✨ SYNOPSIS ✨

s32 igb_validate_nvm_checksum_i210 (struct e1000_hw *hw );

that's it. that's the whole vibe check. one arg, one s32 return. iconic.


πŸŽ€ ARGUMENTS πŸŽ€

  • hw β€” a pointer to the HW structure 🫢 literally just handing the function the hardware so it knows what to look at. main character pointer energy tbh.

πŸ”₯ DESCRIPTION πŸ”₯

so here's what she does: igb_validate_nvm_checksum_i210 calculates the EEPROM checksum by reading and adding each word of the EEPROM, and then she verifies that the sum of the EEPROM is equal to 0xBABA πŸ‘‘

like β€” read the words, add 'em up, and if the total comes out to 0xBABA, we slay. that's the whole test. 0xBABA is THE number. periodt. πŸ’œ

ngl the whole crew lives in ./drivers/net/ethernet/intel/igb πŸ¦‹ go read them, they're all valid and accounted for ✨
