✨ amdgpu_eeprom_xfer(9) ✨

okay bestie, welcome to the Kernel API Manual entry for amdgpu_eeprom_xfer 💅 this is the function that reads from or writes to an I2C EEPROM device — like, the tiny lil memory chip situation hanging off your GPU's I2C bus. it's giving "low-level but make it iconic" 🎀

🌸 SYNOPSIS 🌸

int amdgpu_eeprom_xfer (struct i2c_adapter *i2c_adap , u32 eeprom_addr ,
u8 *eeprom_buf , u32 buf_size , bool read );

that's the whole signature, no cap — five arguments, one int coming back at you 🫶

🦋 ARGUMENTS 🦋

• i2c_adap — pointer to the I2C adapter to use. like, which I2C bus are we talking to, bestie? this is the one 🔥
• eeprom_addr — the EEPROM address from which to read/write. the exact spot in the chip, u32, very demure ✨
• eeprom_buf — pointer to the data buffer to read into/write from. your u8 *, your little bucket of bytes 🍓
• buf_size — the size of eeprom_buf. u32. please actually get this right or it's gonna be a whole thing 😭
• read — True if reading from the EEPROM, false if writing. main character boolean right here 👑

💖 DESCRIPTION 💖

so what does it actually do? it returns the number of bytes read/written, and -errno on error. that's it, that's the description, periodt 💀

ngl the description section is short and I'm not gonna invent lore about it — if it fails you get -errno, if it works you get a byte count. slay 🌈
