igc_read_nvm_eerd(9)

💅 igc_read_nvm_eerd 💅

ok so bestie, we're in the Kernel API Manual today and the star of the show is igc_read_nvm_eerd(9) — yes that's a whole mouthful, iykyk. it's a function that Reads EEPROM using EERD register, and honestly? iconic behavior.

✨ SYNOPSIS ✨

s32 igc_read_nvm_eerd (struct igc_hw *hw , u16 offset , u16 words , u16
*data );

like, that's the whole vibe upfront. returning a s32, taking all those args, living its best life 🫶

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. literally the hardware bestie handing you the deets 💖
• offset — offset of word in the EEPROM to read. where we're looking, fr fr
• words — number of words to read. how many lil words we grabbing 🌸
• data — word read from the EEPROM. the payload, the main character, the thing we came for ✨

🦋 DESCRIPTION 🦋

so basically — and this is the tea ☕ — this reads a 16 bit word from the EEPROM using the EERD register. that's it. that's the whole flex. not me being obsessed with a single-register read but here we are 💅

ngl, short and sweet, but that's exactly the point: 16 bit word, EEPROM, EERD register. memorize it, you'll get asked. 👑

🌈 SEE ALSO 🌈

• Kernel file ./drivers/net/ethernet/intel/igc/igc_nvm.c — go read the source, bestie, it's giving required reading 📚
• igc_poll_eerd_eewr_done(9)
• igc_read_mac_addr(9)
• igc_validate_nvm_checksum(9)
