GUC HWCONFIG BLOB UAPI(9)

💅 GuC HWCONFIG blob uAPI 💅

okay so bestie, this is the GuC HWCONFIG blob uAPI(9) page from the Kernel API Manual, and it's honestly a short one — we love a low-effort icon ✨🫶

The GuC produces a blob with information about the current device. i915 reads this blob from GuC and makes it available via this uAPI. That's the whole plot, no cap 💖

The format and meaning of the blob content are documented in the Programmer's Reference Manual. That's where the actual lore lives, iykyk 📖🦋
