Hey guys, following this guide for the mentioned purpose: https://www.derekseaman.com/2023/06...u-vt-d-passthrough-with-intel-alder-lake.html
It installs srvio drivers and then passthrough raw device.

I can see the graphics card in my Ubuntu VM:
Code:
lspci | grep VGA

00:02.0 VGA compatible controller: Device 1234:1111 (rev 02)
00:10.0 VGA compatible controller: Intel Corporation Alder Lake-P Integrated Graphics Controller (rev 0c)
.

Although I don't think the gpu is functional:

Code:
ls -al /dev/dri
total 0
drwxr-xr-x   3 root root      80 Jul  6 01:15 .
drwxr-xr-x  19 root root    4160 Jul  6 01:16 ..
drwxr-xr-x   2 root root      60 Jul  6 01:15 by-path
crw-rw----+  1 root video 226, 0 Jul  6 01:15 card0

What other steps do I need to follow to make Alderlake iGPU transcoding work with Plex?

Intel Nuc 1240p
