🎀 serial_number(9) 🎀

okay so bestie, you found the Kernel API Manual page for serial_number(9) — and it's giving “one tiny sysfs file, one very specific job.” 💅✨

💖 serial_number 💖

The amdgpu driver provides a sysfs API for reporting the serial number for the device. The file serial_number is used for this, and it returns the serial number as returned from the FRU. 🫶

⚠️ NOTE: This is only available for certain server cards. No cap — don't go looking for it on every card. 😭
