Resolving the error "Possible missing firmware /lib/firmware/i915/"

Linux

I decided to switch to the domestic Runtu OS. The lightweight operating system is installed on an SSD and flies.
The only drawback is the error "Possible missing firmware /lib/firmware/i915/", which is displayed when updating the system kernel. The solution is below.

Solving the problem

1) Repeated the command sudo update-initramfs -u to reproduce the error:

update-initramfs: Generating /boot/initrd.img-5.10.0-1044-oem

W: Possible missing firmware /lib/firmware/i915/tgl_huc_7.5.0.bin for module i915

It can be seen that the update-initramfs program complains about a missing file tgl_huc_7.5.0.bin

2) Downloading the file directory from the page git.kernel.org

3) Upload the file to the local disk tgl_huc_7.5.0.bin- the Internet browser saves it by default to the folder "Downloads".

!!!In Linux Mint did the same with the modules skl_guc_49.0.1.bin, bxt_guc_49. 0.1.bin, etc., using the command file to download (wget):
download_i915.zip

after downloading files, copy *.bin to the folder /lib/firmware/i915

The same file, but for loading modules for rtl81xx network cards:
download_rtl81xx.zip

4) Copy the file from the "Downloads" folder to the /lib/firmware/i915 directory:

sudo cp tgl_huc_7.5.0.bin /lib/firmware/i915

or, in the case of multiple bin files in Linux Mint:

sudo cp *.bin /lib/firmware/i915

If the directory i915 no, it should be created.

I did the same with *.fw modules. But copying to another folder:

sudo cp *.fw /lib/firmware/rtl_nic/

If the directory rtl_nic no, it should be created.

5) Executing the kernel update command:

sudo update-initramfs -u

When the command is executed, a completion message will be displayed:

under Runtu
update-initramfs: Generating /boot/initrd.img-5.10.0-1044-oem
under Debian 12/Sid:
update-initramfs: Generating /boot/initrd.img-5.14.0-2-amd64

There are no more errors related to firmware/i915!

6) Rebooted Runtu - no problem. In Linux Mint after updating the initramfs there is no problem either.
