12th Gen Intel UHD 770 (Alder Lake) iGPU support

[kzsolt4444]

Hi all!

Before i spend my money i want to know if my plan can work.
I want to upgrade my system to use a i5-12500T (with uhd 770 iGPU)

Can you please tell me if it is officially supported by the current PROD version of truenas scale (TrueNAS-22.12.3.3)
I mean using its iGPU for hardware transcoding on Plex and Nextcloud apps.

Is there anybody here who actually using any Alder lake CPU (its iGPU) for hardware transcoding? If yes, was it working "out of the box", or you had to make some magic to get it working?

Thank you!

I would also like to know if anyone has this setup working. I have an Alder Lake CPU, a i5-12400, UHD 730 graphics, and when I run:

# dmesg | grep i915

I am getting these errors in the output:

i915 0000:00:02.0: Direct firmware load for i915/tgl_guc_62.0.0.bin failed with error -2
[drm] GuC firmware i915/tgl_guc_62.0.0.bin: fetch failed with error -2
[drm] GuC is uninitialized

Any feedback is greatly appreciated :)

Officially supported? No

I don't use Plex and Nextcloud, but I do use Jellyfin. And I have hardware transcoding working.

Yes, no not out of the box, but had to type some magic words to get it working.

cd /tmp
git clone --depth=1 https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp -rn /tmp/linux-firmware/i915 /usr/lib/firmware

The above should copy any updated firmware files into the i915 firmware directory without overwriting existing files.

sudo midclt call system.advanced.update '{"kernel_extra_options": "i915.force_probe=4680 i915.enable_guc=3"}'

Replace 4680 with your id as required. The parameter enable_guc=3 enables loading of both the HuC (HEVC encoding) and GuC (everything else) firmware.

sudo reboot

Reboot.
After rebooting and getting back to a command prompt, check dmesg again and see what the output is.

You can also check to make sure you can card(s) and render* in the /dev/dri directory.

thank you very much

You saved me! Thank you for your efforts, though there was one piece (!) missing I want to convey to any other complete linux noobs that run into the same issue. When I tried to copy the files into the firmware directory, I was met with a read-only filesystem error, here are the commands to get past that.
First find out what the filesystem is

df /lib/firmware

Then remount the filesystem as read write

sudo mount -o remount,rw filesystem

Finally once you have copied the files over, its probably best to remount it as read only

sudo mount -o remount,ro filesystem
