Intel i915 GuC and HuC microcontroller firmware support

Internal support code inside the Intel i915 graphics stack that loads and communicates with the on-GPU GuC and HuC microcontrollers. These are firmware-driven helper engines on Intel integrated GPUs (Skylake-era and newer) that offload command submission scheduling and accelerated video decoding tasks.

recommendation

This is not actually a standalone driver directory; it is a subcomponent of the Intel i915 graphics driver that handles communication with the GuC (Graphics microcontroller) and HuC (HEVC microcontroller) firmware blobs embedded in modern Intel GPUs. It exists only as internal plumbing for the larger i915 driver and has no independent lifecycle of its own.

codex reasoning notes (technical)

Not a driver directory: nested i915 GT uC support code for GuC/HuC microcontroller/firmware handling, not a standalone kernel-bound hardware driver.
