Hey all,
I’m on the new RC1 testing and I couldn’t get intel_gpu_top to recognize my new GPU (even with sudo).
I’ve pulled it out and went back to my old nvidia for now until I can find more information on this. Do I need to install or do something else in particular? I thought support for ARC was in the kernel now.
They mentioned this on one of the recent T3 episodes - there is ARC support in the kernel, but not for the Battlemage cards. Probably won’t be supported for a while, unfortunately. I think there are some very sketchy experimental things you can try, but they are probably unadvisable.
Yep, that’d be me. AMA, I guess.
The xe driver does exist in the kernel but it’s very immature - mine was segfaulting trying to transcode video - and the Battlemage cards can’t fall back and use the legacy i915 set.
The userland software like intel_gpu_top and ffmpeg also still seems to be missing a few critical pieces to talk to the B-series.
Ah
Thank you for letting me know.
Isn’t this resolved in the latest kernels like 6.14?
It might be, but we’re using the 6.12 LTS kernel in 25.04.
Bottom line: TrueNAS is an appliance OS based on a LTS branch, not a rolling distro.
To rush fror brand new harware as soo as it hits retail is NOT a good idea…
Arc B may get support in 25.10 or 26.04.
How is battlemage looking in Golden Eye beta?
Has anyone gotten it to work?
I’d also love it if anyone can share any piece of info about the state of battlemage support in future updates! See, now we’re 2 people asking about it, not just 1! It’s a big difference! 
Hello, what about creating a LXC container? if you need the card for an application that can be installed in a container then you may use your Intel card using the official drivers. Containers | TrueNAS Documentation Hub
Intel website indicates that there are drivers for Linux (Ubuntu) including * Intel® Arc™ B580 Graphics https://www.intel.com/content/www/us/en/products/sku/241598/intel-arc-b580-graphics/downloads.html
Since the Ubuntu image is available in the list of containers in TrueNas it may work in the meantime.
I know it works in Ubuntu, although I have no idea if it’d work in an LXC container. But I’m learning as I go, and going with the “don’t use your OS”-route isn’t really an option for me at the very least. 
I saw the announcement about goldeneye from almost 3 weeks ago after I had written my previous post here, so apparently it still needs confirmation about compatibility and functionality with the driver (as was also mentioned earlier in this thread, back from April), but there’s no estimation provided as to how long something like that might take even in the announcement from almost 3 weeks ago so I’m flying blind right now.
The only estimation I’ve found as of yet, is the one provided by etorix a few posts before this one, from April. Which I’d assume is a mostly blind guess as well, so it’s a very unfortunate state right now for me at the very least.
It has been made very clear that truenas isn’t an OS meant for new gear, and the announcement made it clear that it’s thanks to nvidia themselves that the 50xx-series will get support in goldeneye despite the cards being newer than the battlemage cards, but I’m living on hope right now that the confirmation will be done sooner rather than later for the intel xe driver even though I have no clue how long something like that might take.
Right now, I guess I’m just hoping someone somewhere out there in the wild can provide any insight as to how long such a confirmation might take.
There are literally dozens of us! Dozens!
Sadly, the situation hasn’t changed as far as I can tell with 25.10 - the kernel driver included for xe still has issues with transcoding. Passthrough as a VM to a newer kernel works (if your board will allow for ReBAR passthrough, or your workload doesn’t need it) but in-host libva was still barfing.
I was really hoping the update would have addressed this. I was thinking of getting a b series card for my server later this fall when it goes on sale.
Hopefully someone can update this chain and let us know.
We’re investigating the viability of basing 26.04 on Debian 13, which would bring a kernel update - and hopefully Battlemage support.
