It is now the official version 7.20，and I would like to ask if this plug-in can be used normally on the latest platforms?

Intel Core Ultra Processor ( Arrow Lake)

i bought an Arc Pro B50. Plugin page shows:

Support page states: "Intel® Arc™ Pro B-Series discrete graphics family (Formerly Known as Battlemage) supports Single Root IO Virtualization (SR-IOV)"

i updated my bios to the latest version (P3.90 on ASRock B550M Steel Legend).
enabled ReBAR and SR-IOV and booted unraid:

wth does "VF mode" even mean? google didnt help and even chatbots didnt really help ...
what can i do?

regards and thanks in advance

@Sizukaze The plugin hasn't changed. There is still no support AFAIK. For a more detailed version, @ich777 would be the right person.

@hoschy VF are virtual functions... If activated you can use these VFs like they were dedicated GPUs.

The newer GPUs will only support SR-IOV via the xe2 driver, not via the old i915 driver (which is what this plugin uses). i915 isn't really being updated any more. The new driver provides native support for SR-IOV out-of-the-box, but only for some GPUs at the moment.

As of Linux 6.18, SR-IOV in xe2 is enabled for Tiger Lake (11th gen), Alder Lake (12th gen), Raptor Lake (13th and 14th gen), and Arctic Sound (data center GPUs). However, I'm not sure if Unraid include this driver in their kernel build.

There's a long thread about it here: https://github.com/intel/linux-intel-lts/issues/33

thanks for clarifying 😎
i got an alternate unraid kernel from thor2002ro (6.18RC4). at least "GPU Statistics" recognizes the card as "Battlemage G21 [Intel Graphics]" now.
is there any chance i can use the card for now? is there an ETA for propper Battlemage support in unraid? does anyone know? 🙈
its the ideal card for a NAS in my eyes. (max 70W, 16GB, all major codecs in decoding and encoding, ML Support, etc.), wouldnt want to return it 😓

Hey,

i am in the same boat ;) I installed thors Kernel and the is "better" recognized, but is nearly working the same as before. SR-IOV is not working.

I thought the kernel is missing some features, for my understand what would be necessary for the unraid team to update to get SR-IOV working?

After installing the plugin the number of VFs is set to 2 (available 7). Should I increase the number? What would that do?

Create more virtual(VFs) GPUs upto a max of 7. Will use more memory also for vRAM

not if you run it as docker ;)

vgpu's are basically meant for VM's as by design they need exclusive devices (sample a vgpu).

Linus released the final version of kernel 6.18 yesterday (https://github.com/torvalds/linux/releases/tag/v6.18)
ich777 released kernel 6.17.9 for unraid last week (https://github.com/ich777/unraid_kernel/releases) (maybe for the next unraid release?)

from my unterstanding, for our Arc Pro cards to be fully functional, we need kernel 6.18 (for full SR-IOV support) and a driver/tool/plugin to configure the card and split its "power" to different docker containers (maybe?🤷‍♂️)

And since the Battlemage Arc Pros only run on the newer XE driver model, we cant use it (cause all available drivers/plugins for unraid are still i915)

so we're still out of luck and have to wait for someone to write it 😢

am i correct? i dont know, but thats what i learned so far.

regards

So I installed the 'Intel GPU TOP' plugin and thereafter the 'intel Graphics SR-IOV' driver. That worked fine so far. I also added the following to /modprobe.d/i915.conf:

options i915 force_probe=!4690

After checking:

lspci -nn | grep VGA

00:02.0 VGA compatible controller [0300]: Intel Corporation Alder Lake-S GT1 [UHD Graphics 770] [8086:4690] (rev 0c)

09:00.0 VGA compatible controller [0300]: ASPEED Technology, Inc. ASPEED Graphics Family [1a03:2000] (rev 52)

The result in the 'system driver section' after reboot is:

The driver is disabled (blacklisted).

I haven't really installed other plugins which have something to do with the graphical interface besides 'GPU stats'.

How can I avoid this?

Hi. Am i reading this thread right, that SR-IOV is currently broken?

I came home to my windows VM crashed. When booting up again, my Intel Alder Lake-S GT1 UHD 730 iGPU has errorcode 43. Been fiddeling a few days now with no luck fixing it.

Any help apriciated.

Edit: Cause of this?

xe 0000:00:02.2: Your graphics device 4692 is not officially supported
by xe driver in this kernel version. To force Xe probe,
use xe.force_probe='4692' and i915.force_probe='!4692'
module parameters or CONFIG_DRM_XE_FORCE_PROBE='4692' and
CONFIG_DRM_I915_FORCE_PROBE='!4692' configuration options.

Edit2: Under Drivers:

i915 (2025.07.22-sriov.6.12.39)

Linux i915 driver with SR-IOV support, port from github.com/intel/mainline-tracking.git v6.12 branch

Disabled

gpu/drm/i915

Blacklist i915

Is this causing it ?

Asking AI, and doing what AI said, the xe message is now gone. Opening the files edited, and the edits are gone after a reboot.

Windows still on code 43.

AI:
3. Permanent Use (via Modprobe)

If you prefer configuring module options directly:

• Create a configuration file: sudo nano /etc/modprobe.d/xe.conf.

• Add: options xe force_probe=4692.

• Create another file: sudo nano /etc/modprobe.d/i915.conf.

• Add: options i915 force_probe=!4692.

Update your initramfs: sudo update-initramfs -u.  <---- unknown command.


Going with the critical QEMU overrides from this https://forums.unraid.net/bug-reports/stable-releases/712-vm-intel-gpu-passthrough-to-monitor-stopped-working-r3855/ thread, results in:

FML. Probably cause machinetype is not Q35 ... testing..

Nope. Not it. Next....

A reinstall of Windows 10 seems to be the thing. Currently installing all Intel drivers with no problem.
Windows 11 is the problem here, not the plugin.

Support for Bxx cards will be in 7.3 along with ability to set sr-iov for nics and gpus. The plugin will still need to be used for i915 gpus as it still needs a modified driver.

I get output to a physical monitor using Unraid 7.2.3, an i5-13500 CPU, and a displaylink USB hub. It works great. Thanks so much for this!

Would love to hear more about your experience with the display link! What do you use the monitor output for and is it working well? Is there something this solution can’t handle well? I’m expecting this to work ok for daily “office” usage but not so well for video streaming, graphics editing and gaming, for example.

In my experience it's perfectly fine for office work and watching videos. No tears or anything. I don't notice any difference between display link and bare metal igpu. I haven't tried any gaming, so I can't speak to that. It may depend on the displaylink adapter you use. I have this one: https://www.amazon.com/Docking-Station-GIISSMO-Universal-Charging/dp/B0C3GG1JDP.

I just got this trying to upgrade to Unraid v7.2.5

Waiting.. What should I do?

I would also like to report Intel gpu Virtualization not working after 7.2.5, hopefully a quick fix.

hope there is a fix for this so it will work in 7.2.5

It is no longer available in version 7.2.5. Can it be updated?

Hello, I am a China user, and my English is not very good. I have a problem now, that is.Hello, I am a China user, and my English is not very good. I have a problem now, that is, I saw that the plug-in was updated to 7.2.5 last night, and I found that this plug-in could not be used after the update, so I returned 7.2.4 again. I checked that it was 6.12.54 if it was installed from CA, but I saw that ich777 was updated to 6 for this plug-in on github. Or tell me how to update manually.

just here to report the same. Fails with 7.2.5 I will also need to roll back 7.2.4 as I use this quite a bit
