I installed the Intel B580 Battlemage in my Unraid server.
Naturally I installed the available drivers along with it from CA and I can see the card in the Hardware list inside Unraid
Have anyone got it to work with any containers/apps like Emby/Plex/Jellyfin, Immich, Fileflows, and so on?
I am on Unraid version 7.3.1

Thanks

Drivers are baked into the kernel, nothing extra needs to be installed for intel/amd gpus to function on unraid/linux.

It works the same as any intel Arc GPU, just have to pass it through to the containers.

Add the extra parameter --device=/dev/dri

Are you really sure it is that simple?
I know Plex did not have support until lately and issues are still reported and I know for a fact that HW acceleration on Frigate does not work

Both of those are issues with these applications, not with Unraid.

Best to work with the folks supporting the applications, either in the docker's support thread or with the application support itself.

It's supposed to be that simple yes. But like ConnorVT said, the docker containers must also support the GPU which I know for a fact plex does. They recently added B-series GPU support.

I have also read that Plex does but strange as it seems, My Plex instance sees the card but when I try to transcode the stream crash.
So even though the card is used by the container I think there are driver or integration issues.

I have seen a number of cases where wonky transcoding or playback issues are due to a corrupted codec file. You can safely delete the Codecs folder from your Plex appdata. Stop Plex, delete the folder, and restart Plex. It will create and repopulate the folder with fresh codec files. I have had several folks post feedback they have done this and it resolved their issues.

Also be sure to test with a dedicated PLEX client, and not the web browser. The web browser is well known to have issues, especially when switching resolutions or transcoding bandwidth. Switching off subtitles is also a must, as subtitles will most times switch to CPU transcoding.

The solution was actually quite simple.
My server, A Dell R740xd does support Resizable BAR but in a different memory space than expected from the card.

This means the GPU tries to address marts of the memory that is not accessible on this type of motherboard.

So this type of GPU will never work on enterprise grade hardware. It is a card designed for gamin on consumer hardware.

I tried everything and with help from various places this was the conclusion.

I totally forgot ReBar is required for intel GPUs... I honestly didn't realize it was necessary for an unraid use-case. I figured it had more to do with gaming than just using the card in general.

I have ordered an intel arc b50 GPU but my motherboard (supermicro h11ssl V2) bios does not support resizable bar. Is it vital in unraid to have this option in the bios to use this GPU? I plan on splitting the GPU using SR iov between windows vm's and docker. Thanks des.

It appears that rebar is required for the intel ARC GPUs to function in any capacity on linux. This is due to intel and the drivers more than unraid.

Thanks for the feedback. I will probably end up sending this GPU back then. Disappointed, but it is what it is I guess.
