The 22.04 hardware enablement package was updated a few minutes ago installing kernel 6.2.0-26 on the system. The problem is that during the image generation this message appeared:
W: Possible missing firmware /lib/firmware/i915/dg2_huc_gsc.bin for module i915
How is this fixed please?
I am posting this answer, although I think it may not be necessary since a few minutes ago on August 5, there was a linux-firmware update that may have fixed the issue.
In case the issue still exists after this update, the way to fix it is by downloading the required .bin file from here and copying it as root to the /lib/firmware/i915 folder. Right after that, the 6.2.0-26 image needs to be regenerated by executing:
sudo update-initramfs -u
This will update the latest kernel image only, which in this case is the 6.2.0-26 image. There should be no errors or warnings after this but the system should be rebooted for the updated kernel to be loaded.
From Debian bug #1040012 this looks like it was due to a packaging oversight in firmware-misc-nonfree and has been resolved - that will filter down to ubuntu soon hopefully.
What the module actually is is a bit mysterious the commit adding it to the kernel just says "i915: Add HuC 7.10.3 for DG2". But, from discussion on intel-gfx this is basically all around a transition in the intel graphics driver firmware handling.
