> [ Impact ]
> 
> Missing HUC firmware. For whatever it is required for, it won't work without the firmware.
> 
> [ Fix ]
> 
> Upstream linux-firmware commit 8f86b5ab3e051170ea240fc409d457e16e24bc21.
> 
> [ Test Case ]
> 
> $ cat /sys/kernel/debug/dri/1/gt/uc/huc_info
> 
> Should report HUC FW information.

> [ Where Problems Could Occur ]
> 
> Limited to i915 DG2 (Arc2?) GPUs.

> [ Original Description ]

> $ sudo update-initramfs -k $(uname -r) -u
> update-initramfs: Generating /boot/initrd.img-6.2.0-26-generic
> W: Possible missing firmware /lib/firmware/i915/dg2_huc_gsc.bin for module i915

> i915/dg2_huc_gsc.bin seems to be missing. While this is an experimental (?) Intel driver for Arc2 dedicated GPUs, and some of these products are no longer being sold, there will probably be people out there using it, and wishing to use the newer driver and HUC support.
