fru_id(9)

💅 fru_id — kernel API manual, but make it make sense

okay bestie, so this one's from the Kernel API Manual, section 9 (that's the kernel-adjacent girlies, iykyk). It's called fru_id and no, it's not a new app, it's a sysfs thing. Let's get into it 🎀

✨ NAME ✨

fru_id — the amdgpu driver's lil sysfs API for reporting the FRU File Id of the device 🦋

🌸 DESCRIPTION 🌸

okay so the amdgpu driver literally provides a sysfs API for reporting the FRU File Id for the device, and the file fru_id is the one that does it. Ask it nicely and it returns the File Id value — exactly as returned from the FRU, no edits, no glow-up, periodt 💅

⚠️ NOTE: this is only available for certain server cards. so if you're on some regular desktop GPU and fru_id isn't there? that's not a you problem, it's just not that girl 🫶
