Does this answer your question? Possible missing firmware /lib/firmware/i915/* for module i915 — Philip Couling, Apr 28 '20 at 14:12
@PhilipCouling I tried it, But it either gives me no answer, or a package that is already installed. — Thorbjørn E. K. Christensen, Apr 28 '20 at 14:48
@jsotola how to fix this. What packages should I install? what firmware could I be missing? etc. or, if it isn't a problem, should I be bothered by it at all? — Thorbjørn E. K. Christensen, May 04 '20 at 15:32
ok, then edit your post and include the questions please ... they do not belong in comments — jsotola, May 04 '20 at 15:39
If your devide works, just ignore it. If it doesn't work, add nonfree to your repository and search for the package that own any of those files, like apt-file search i915/icl_dmc or dpkg-search -D i915/icl_dmc. And if any package own that file, you can install it with apt and reboot the computer. — Anders, Feb 24 '22 at 04:30

Please try:

change to root (either via su or sudo su, depending on your distribution's configuration)
install git
```
apt install git
```

retrieve the firmware

cd /tmp
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

"import" the i915 firmware

cd linux-firmware/
cp i915/* /lib/firmware/i915/

update the initramfs
```
update-initramfs -u
```

Please elaborate. – WGRM May 04 '20 at 17:40
Or better yet, search for the package that contain the firmware. It isn't that hard. Then you don't need to download it at al. – Anders Feb 24 '22 at 04:31

Sometimes a driver starts supporting additional hardware that the system does not have firmware for yet, or hardware for which the firmware cannot be legally distributed (e.g., chips that appear only in Apple hardware). Additionally, there's also hardware where the firmware enables some performance improvement (e.g., TCP segment offloading for network cards) but the chip works fine without it.

Since this is your graphics card, if your graphics are fine and you have OpenGL (3D) support working, then there's nothing to do. If your card isn't performing well, you can find the relevant firmware package and install it. If it's already installed, then there's nothing you need to do. Debian will package the firmware for additional cards in due time, and the warning is harmless: it's just there to tell you that you may want to install the firmware if it's available.

sadly my graphics card isn't working well. I have had a few crashes. — Thorbjørn E. K. Christensen, May 04 '20 at 15:27
Just use apt-file search i915/icl_dmc or dpkg-search -S i915/icl_dmc and it will tell you which package you need to install for loading the firmware. That is a general answer, by the way. You can search for any file for which package own them. Works on Debian and any distribution derived from Debian. — Anders, Feb 24 '22 at 04:34
