"W: Possible missing firmware /lib/firmware/i915/ski_guc_49.0.1.bin for module i915"

07 Nov 2021

I was running apt for a routine kernel upgrade, and I saw this:

update-initramfs: Generating /boot/initrd.img-5.11.0-37-generic
W: Possible missing firmware /lib/firmware/i915/ski_guc_49.0.1.bin for module i915

This did NOT seem to work:

# apt install --reinstall linux-firmware

But this did the trick:

$ mkdir ${HOME}/FIRMWARE
$ cd ${HOME}/FIRMWARE/
$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
$ su -
# cd /home/mwood/FIRMWARE/linux-firmware/i915/
# cp -i ski_guc_49.0.1.bin /lib/firmware/i915/
# update-initramfs -u -k all

It turns out there were other missing items too, but I think I just ended up copying all of the *.bin files into /lib/firmware/i915 and that seemed to make the error messages go away.
