💅 ixgbe_read_i...ric_unlocked(9) 💅

okay bestie, welcome to the Kernel API Manual — yes that's the actual manual name, it's giving "official document, but make it cute." today's main character is ixgbe_read_i2c_byte_generic_unlocked, which is a lot of name, but she earned it. 🎀

✨ NAME ✨

ixgbe_read_i2c_byte_generic_unlocked — reads an 8 bit word over I2C. that's it, that's the whole vibe. one byte. over I2C. slay. 🌸

🦋 SYNOPSIS 🦋

int ixgbe_read_i2c_byte_generic_unlocked (struct ixgbe_hw *hw , u8
byte_offset , u8 dev_addr , u8 *data );

it returns an int, and it takes four things. we're gonna go through them one by one, don't worry. 💖

🎀 ARGUMENTS 🎀

  • hw — pointer to hardware structure. literally the hardware. the whole thing. she's a struct ixgbe_hw * and she's the main character energy of this function ngl. 👑
  • byte_offset — byte offset to read. it's a u8, it tells you where in the byte-land we're looking. 🍓
  • dev_addr — device address. also a u8. this is who we're talking to on the bus, iykyk. 🦋
  • data — value read. it's a u8 *, so it's a pointer, so the function can drop the value it read in there for you. it's giving "here's your result, bestie." 🫶

💜 DESCRIPTION 💜

so what does she do? she performs a byte read operation to the SFP module's EEPROM over the I2C interface at a specified device address. 📖✨

that's the whole thing, no cap. one byte, from the SFP module's EEPROM, over I2C, at the device address you handed her. iconic behavior honestly. 🔥

also note the _unlocked in her name — she's the unlocked flavor of this operation, which is exactly what the name says and nothing more, okay? i'm not out here inventing lore. 🙈

🌈 SEE ALSO 🌈

buckle up bestie, this list is long, but every single one of these made the cut, fr fr. 💀

see? all of them. not one skipped. we don't do that here. 💅✨

and that's the page!! tysm for reading, bestie, you ate that 🍓

this cutie dropped from ./drivers/net/ethernet/intel/i... in October 2026, and this whole thing is the Kernel API Manual, so like… cite her properly if you reference her in your paper. mwah 💋🦋💖
