[Plugin] Intel-GVT-g

[gilladur]

Hi all,

 

don't know why, but the iGPU of my Xeon E-2246G is not showing up in the plugin.
I'm using it without any issue for transcoding in Jellyfin and it is also showing up under system devices:

 

 

My Go file is also looking clean and syslinux is on default:

#!/bin/bash
# Start the Management Utility
/usr/local/sbin/emhttp &

cp /boot/custom/docker-shell /usr/local/bin

# load keyboard layout
loadkeys de-latin1-nodeadkeys 

# disable telnet and FTP

sed -i -e 's/^telnet/#telnet/;s/^ftp/#ftp/' /etc/inetd.conf
/etc/rc.d/rc.inetd restart 

 

I've added my diagnostic file.

If I try to use the iGPU in VMs without your tool via VFIO exclusively I'm getting this error:

Execution error
internal error: qemu unexpectedly closed the monitor: 2021-05-18T16:08:49.062069Z qemu-system-x86_64: -device vfio-pci,host=0000:00:02.0,id=hostdev0,bus=pcie.0,addr=0x2: vfio 0000:00:02.0: Failed to set up TRIGGER eventfd signaling for interrupt INTX-0: VFIO_DEVICE_SET_IRQS failure: Transport endpoint is not connected

 

As I just have this iGPU it should not matter but I'm having an dummy plug connected to my VGA output.

In Bios I have set iGPU to VGA priority to onboard and also tested offboard.

 

Any clue what could be the issue?

Thank you for the screenshot, actually the iGPU doesn't show up because it is named differently on your system, I will look into this and update the Plugin, don't know if I'm able to do it tomorrow but I try my best.

But if you do that you can't use it in Jellyfin for transcoding...

I know, just tried it to be sure to test everything.
Thank you for looking into my issue 🙂

Wrote a PM to you, have a fix, I think...

First post mentions docker containers.

How do we apply this to containers? ie plex transcoding.

I don't know what you mean exactly, these are two different things.

This plugin simply enables GVT-g for the iGPU so that you have the ability to use vGPUs in your VMs and also use it in your Docker container.

 

If you don't need vGPUs then simply install the Intel GPU TOP plugin and I recommend also installing the GPU Statistics plugin from @b3rs3rk to see the iGPU utilization on the Unraid Dashboard and then add a new Device to your Plex container '/dev/dri' (without quotes) like so:

 

After that enable Hardware transcoding in the Plex container and you should be good to go.

 

 

Just to clarify:

Intel GVT-g = enables the iGPU for vGPUs and Docker containers

Intel GPU TOP = enables the iGPU only for Docker containers (needed if you want to use the GPU Statistics plugin)

GPU Statistics = enables you to see the utilization from the iGPU on the Unraid Dashboard (needs the Intel GPU TOP plugin installed)

How having a VM with a VGpu in use affects the hardware transcode performance of the dockers (Plex transcodes) ?

That depends and is a question that I can't answer since I don't know which CPU do you own and how many streams you want to transcode in Plex and what you do in the VM with the vGPU.

 

I can only tell you when you do light Desktop work (Internet, Youtube, Word,...) it will do pretty much nothing to the transcoding.

 I just tried it and everything is running great, no more lag when dragging windows and there is no dropped frames when playing videos inside the VM.

 

Will try it when I have the usual transcodes running (7 transcodes, 2 of those 4k HDR).  

 

I have an i3 7100 and have an i5 11400 in a corner waiting for HDR transcode support on unraid/plex.

 

Thank you for this

Hi,

 

just a short feedback from my side. With your last pushed update everything seems to work.

I only made the mistake not to set an password for the windows login and then I've stuck at the remote desktop connection, which didn't allow me to log in without an password.

So new VM with the needed password and I'm in with a working iGPU.

The only issue I've encountered so far. If I reboot I can't connect to the VM - after force stop and restart it working.

Thank you @ich777 for the plugin and the great support!

This should be easily solvable by:

1. Shutting down the VM
2. Remove the vGPU in the plugin settings
3. Start the VM
4. Connect over VNC to the VM and set a passwort
5. Shutdown the VM
6. Add the vGPU again
7. Eventually make the necessary changes to only enable the vGPU

This is really strange since this never happened to me, are you on the latest Windows version with all updates and the latest GPU driver?

Eventually send me the Diagnostics after this happens (Tools -> Diagnostics -> Download -> drop the downloaded zip file here in the text box) and also the log from the VM itself.

[gilladur]

If this happens I get this error in the log:

qemu-system-x86_64: warning: guest updated active QH

I've added my diagnostics to the answer.

It can be the case that you have to disable GuC/HuC, I will release an update for the plugin today so that switching the mode is possible in thhe GUI but a restart after switching the mode is necessary.

Hello all user,

before i go more in the deep search on my system, because its not running for me.

i have follow hardware

internal graphics intel i5 11400

mainboard asrock z590itx

software unraid 6.92 / intel gpu tools / Intel GPU TOP / Intel GVT g

must this hardware running or isnt supported?

i want to use hardwareencoding in plex server in a docker (dev/dri)

but the subfolder in this directory dont exists

and when i make manual the command modprobe i915 nothing come return.

thnx for your help.

It is very likely that it isn't supported by now since this is a really new CPU or you need another flag that you need to add to the syslinux config, what do you think @SimonF?

Can you give me the output of 'lsmod' (without quotes) after issuing the command?

 

I think there is a thread how to get rocket lake iGPUs working on this version of Unraid.

 

You only need under normal circumstances Intel-GPU-TOP of you only want to activate the iGPU for transcoding in Docker containers.

You can accomplish this too by adding 'i915.force_probe=4c8b' to your syslinux configuration:

 

I would strongly recommend doing it this way, otherwise the GVT-g plugin, if you ever want to use it won't work.

Hopefully in a later kernel this probe wont be required.
