QuickSync linux on a tigerlake

[Ratatouille 11]

I need help to set up the drivers for QuickSync on a 11 th gen although I got NVIDIA working but being curious I want to see the difference between both but so far I am unable to get quick sync running any help would be welcome Before on a Coffee Lake vaapi was very easy to implement but not on tiger lake.?

Which kernel version are you running?

[Ratatouille 11]

This

Kernel

Linux 5.10.0-0.bpo.9-amd64

[Q-Droid 634]

That kernel version has support for Tiger Lake and as far as I can tell they also still use the i915 kernel driver which should load on boot. If it doesn't you may have to tweak kernel boot parameters to get the module to load. If you can't find graphics devices under /dev/dri then chances are the kernel driver hasn't loaded.

After that Emby should take over as it includes the drivers for Intel QSV. But if you also want to run other OS and command line tools related to Intel graphics they you would have to find and load those packages.

Ok I am using debian Debian GNU/Linux, with Linux 5.10.0-0.bpo.9-amd64 I have no idea how to install the driver since dev/dri does not activate transcoding like it use to plus vainfo give me error

rootI:~# vainfo
error: can't connect to X server!
libva info: VA-API version 1.4.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)

Is hw transcoding not working in Emby? Like I said before and unless something has changed Emby includes the drivers (libraries) for Intel hw. So as long as the kernel module for DRM loads it should be fine. The command line libva utilities don't work for me either (Coffee Lake) because my OS is older and I would have to build them. But as long as Emby works I don't really care.

Run lsmod | grep i915

Since your CPU is very new you might need a specific version of Emby for support (beta?). Can you attach the hardware detection log?

 

[Ratatouille 11]

 

I think the drivers are not loaded and I don't know how to install them .

I am unable to upload at this moment the hardware detection log error code 200 from the site

root@I:~# Run lsmod | grep i915
-bash: Run: command not found

although I am getting

~# modinfo i915 | grep filename
filename:       /lib/modules/5.10.0-0.bpo.9-amd64/kernel/drivers/gpu/drm/i915/i915.ko

host /dev/dri/renderD128 container /dev/dri/renderD128

host /dev/dri/card0 container /dev/dri/card0 give nothing for transcoding

 

[Q-Droid 634]

Omit "Run", the command is lsmod. 

Emby on docker? Then post compose or run options and attach hardware detection log.

but so far you can see Nvidia like I mentioned in first post but of course I want to try QuickSync

Okay, the DRM/i915 kernel module is loaded.

1. Are you running Emby in docker?
2. Since you have multiple GPUs have you made sure the iGPU remains active/enabled in BIOS? I think the option is called "iGPU Multi-Monitor" or something along those lines. Otherwise the discrete GPU is the only one enabled by default.

You mentioned host/container in a previous post. If running in docker you need to make sure the container runtime process has access to the DRI devices. The GIDLIST env in compose/run is used to pass the GIDs with access to the /dev/dri devices.

thank you for helping me 

but my BIOS is in multimonitor I am familiar with the runtime process on my previous cpu I did not have NVDIA I just hve to enanble the regular runc process and devices 

/dev/dri:/dev/dri

or /dev/dri/renderD128:/dev/dri/renderD128

AND /dev/dri/card0:/dev/dri/card0

this is not working this why I think perhaps the driver are not enabled?

 

[Q-Droid 634]

Yes, /dev/dri:/dev/dri is the mapping you want to use.

Have you tried using the official Emby docker image?

It has the option to include additional GIDs.
      - GIDLIST=100 # A comma-separated list of additional GIDs to run emby as (default: 2)

 

[Ratatouille 11]

ok I just  tried

root@:~/mesa# getent group video | cut -d: -f3
44
root@:~/mesa# getent group render | cut -d: -f3
107
 

UID=1000 # The UID to run emby as (default: 2)
      - GID=100 # The GID to run emby as (default 2)
      - GIDLIST=44

 

44 or 107 or 107,44 no joy!

At this point I would install Emby on the host OS to get around docker and make sure that it can detect and use the iGPU. It's pretty much what the devs will ask you to do if they get involved.

There's also this thread and you can check dmesg to see if you have a similar error message. Might need to force probe for your device as well.

Finally ye!

The link above was exactly what I need now I can have VAAPI or quicksync just by changing runc or NVIDIA the issue was on Intel Rocket Lake 11th gen we need to force "i915.force_probe=4c8a" in the kernel @mister steve mentioned it is all over internet https://www.google.com/search?client=firefox-b-d&q=i915.force_probe%3D4c8a
I used this link
https://libredd.it/r/linuxhardware/comments/ms28mk/getting_any_linux_distro_to_work_using_latest/

[Ratatouille 11]

Actually, Now If I used NVIDIA instead of runc I got both and I can check both drivers together but not sure yet if both can works together for transcoding @softworkz ?
