GPU Passthrough

[Chris]

Does the Plex application enable GPU pass through? If yes is it complete or partial? Most importantly is it easy to setup?

[Bram]

GPU passtrough would also be nice for local AI.

[kolin]

I think GPU passthru is a must feature not only for Plex 

[Chris]

Here is how I got GPU passthru to work.

First I logged into the trunas UI and went to System -> Shell
Once in the shell I ran a command to find my gpu slot and uuid

truenas_admin@YOUR-NAS[~]$ midclt call app.gpu_choices | jq

{
  "PCI_SLOT_VALUE": {
    "vendor": "NVIDIA",
    "description": "NVIDIA GeForce GTX 960",
    "vendor_specific_config": {
      "uuid": "GPU_UUID"
    },
    "pci_slot": "PCI_SLOT_VALUE"
  }
}

Then I ran a command to set those values in the plex app

truenas_admin@YOUR-NAS[~]$ midclt call -job app.update plex '{"values": {"resources": {"gpus": {"use_all_gpus": false, "nvidia_gpu_selection": {"PCI_SLOT_VALUE": {"use_gpu": true, "uuid": "GPU_UUID"}}}}}}'

Accessing the truenas ui to enable GPU passthrough. it does seem to work but your mileage may very.

[Magnus]

Hi there! Hardware Passthrough is coming with our VM management.

[jpadgett]

I am just need to figure out the GPU to put in my Dell r530 it has 2 low profile sockets. But I am limited to 25 to 30 watts of draw. Still doing my research.

[Midnight2ss]

Plex took about 15 minutes to installed. there were 0 settings or anything to configure. any setting (Currently in this beta version) to change goes back into the truenas UI

Did you try it in a VM yet?

[silvioslim]

GPU passtrough is what we all plex users need. I hope it works fine

Is it? I purposely brought a 12th gen intel to not have to use a gpu >.<

Ok maybe not everyone…but yes i have a 11th gen and using hw transcode

[Jor]

Yeah we need GPU support.

Attempted to do it via TrueNas UI but have just been getting errors.

[Hirvikarhu]

Easy to use gpu passtrough would be great and if selected gpu is not supported, simply error message would be nice.

Check out the Intel A310.

Thanks

[Vroar]

Don't you need a plex pass for hardware transcoding ?

[Kotice]

would be nice

just out of curiosity (as someone who isnt in the beta yet), the current TrueNAS version has a checkbox that handles the gpu passthrough and does this automagically by its own. i use this right now with my plex setup.

have you tried it? if not, its worth a shot for the rest of your app needs. i wonder if this breaks something in the HexOS interface (i don't think it should, but meh)

I tried the checkbox and would get some error so I googled it and this was the fix I came across. After that it was fine.

After you did this can you still manage the app through HexOS? I haven't gotten to test setting up apps in TrueNAS directly and seeing if Hex sees them at all (I'd assume not), but edited apps I'm not sure of.

The settings button in HexOS just dumps you into the truenas settings for plex. I am not sure if it did that before or not.

[Mr.noobit]

Gpu usage would also be nice, but from my understanding truenas scale dosen't even have a widget for this either on their dashboard. I do not recall if truenas core did been too long since I tried core. I now this is possible on unraid via gpu statistics plugin which would show usage, what apps, and vms that where utilizing in real time along with temps.

[Devil Gamer]

This would be awesome to be able to not only use a gpu but for multiple apps and maybe prioritizes for example if Plex is needing GPU it can take it completely aware from OpenUI while rendering stuff in real time.

Yes, to enable Hardware encoding you need an active Plex Pass:

This ended up working for me! After running these commands though, I did have to go back into the TrueNAS UI and enable the 'Use this GPU' button.
