SOLVED: Trying to get hardware acceleration to work with intel arc a380

[iif2fo]

Huh, I just noticed I installed "firmware-misc-nonfree" previously. I have not
installed "firmware-linux-nonfree", as per the LE instructions.
https://jellyfin.org/docs/general/admini...e-on-linux

I tried that first.

Code:

sudo apt install firmware-linux-nonfree

Then I added i915.enable_guc=3 back in my kernel parameters in /etc/default/grub.

Code:

GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.enable_guc=3"

and then sudo update-grub and rebooted.

Still got the message about the old GuC firmware.

I wasn't sure if firmware-misc-nonfree or firmware-linux-nonfree installed i915
firmware. I didn't want to overwrite the files when I did the git clone later.
This dpkg command gives me an empty result, so I think I'm ok on that front.

Code:

$ dpkg -L firmware-misc-nonfree | grep "/usr/lib/firmware"
$ dpkg -L firmware-linux-nonfree | grep "/usr/lib/firmware"

Next, I downloaded the firmware.

Code:

git clone --depth=1 git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

Since I already had a /usr/lib/firmware/i915 directory, I decided to back that
up first because I noticed the new firmware files are different from my
existing files.

Code:

# backup current
sudo cp -r /usr/lib/firmware/i915/ ./i915-bak

# delete current
sudo rm -rf /usr/lib/firmware/i915/

# install new
sudo cp -r linux-firmware/i915/ /usr/lib/firmware/

Next I ran

Code:

sudo update-initramfs -u
sudo update-grub
sudo reboot

Cool, output looks good.

Code:

I found the guc and huc info files!

Code:

sudo ls /sys/kernel/debug/dri/0000:03:00.0/gt0/uc/guc_info
sudo ls /sys/kernel/debug/dri/0000:03:00.0/gt0/uc/huc_info

I went to the dashboard transcoding page, /dashboard/playback/transcoding.

And enabled these Hardware encoding options

Code:

Enable hardware encoding
Enable Intel Low-Power H.264 hardware encoder
Enable Intel Low-Power HEVC hardware encoder

And now playback works! 🙌 Huzzah! Thanks, TheDreadPirate and nyanmisaka!
