If it isn't in your plugin list anymore I would also check the Plugins Error tab and if it isn't in there either (or if you have no such tab) then do a reboot to be on the safe side first and then do that if you are already on 6.12.4:

 

Yep, you're right, it's right there under errors, don't know how I've never noticed that tab before, I'm guessing it only exists when ther are errors...

I have now adapted the plugin so that users are able to install it on Unraid 6.12.4 without any workarounds and to make sure that packages for upcoming Unraid versions are available. The new plug

I want to thank you for providing this solution and information in this thread! Was reading for a while now and fully managed to get iGPU passthrouh working yesterday.   My used Hardwar

For all who are in need of a plugin package for Unraid 6.12.4 here it is: i915-sriov-6.1.49-Unraid.txz i915-sriov-6.1.49-Unraid.txz.md5   To install them do the following:

Its saying my CPU isn't supported or is in VF mode.

I have a test cpu 11-900t which is reported as being a 'Genuine Intel® 0000 @ 1.10GHz' is this how it's checking the cpu or is it actually checking the hardware...

 

and then if I try the other GVT-g plugin for 11th gen it says..

One of these must work with my 11th gen cpu? SR-IOV  or GVT-g

I've got a Windows11 VM with VF passthrough working but getting the same "Host Encoder" errors in Parsec.

 

Using Remote Desktop Connection from a separate machine works well, it looks like GPU acceleration and a separate audio device are all added without any additional driver install or anything.

 

In order to avoid using a separate machine for RDP, I'm trying to get rdesktop or maybe Reminna working within unRAID GUI boot screen. Steps so far:
Installed these packages:

https://slackware.uk/slackware/slackware64-15.0/slackware64/xap/rdesktop-1.9.0-x86_64-4.txz

https://slackware.uk/slackware/slackware64-15.0/slackware64/l/libsamplerate-0.2.2-x86_64-1.txz

Disabled NLA in Win11 System Properties->Remote tab (Win+R - sysdm.cpl) to bypass CredSSP error:

image.png.1dd6cb6d556cea6e92106ddbd646fe28.png

 

But getting this error when running rdesktop via the GUI boot terminal:

Core(error): locale_to_utf16(), iconv_open[UTF-8 -> UTF-16LE] fail 0xffffffffffffffff
Aborted

 

Parsec I assume has faster streaming but RDP seems the easier to setup - if I can get rdesktop or Reminna working and audio enabled in unRAID GUI boot mode this might be a good option.

If you are already on Unraid 6.12.4 try this:

 

  1. Execute this from a Unraid Terminal: 
    mkdir -p /boot/config/plugins/i915-sriov/packages/6.1.49/
  2. Copy the two files from the above post in the folder: /boot/config/plugins/i915-sriov/packages/6.1.49/
  3. Install the SR-IOV plugin
  4. Execute this from a Unraid Terminal: 
    sed -i '/  modprobe i915 enable_guc=7/ s/.*/  modprobe i915 enable_guc=3 max_vfs=7/' /boot/config/plugins/i915-sriov.plg
echo "# disable autoload old i915 module on boot
  blacklist i915" > /boot/config/modprobe.d/i915-sriov.conf
  5. Reboot

 

This is a really dumb question but how do I perform step 2? I went to MAIN > BOOT DEVICE clicked on my flash drive and enabled sharing by toggling EXPORT to YES and SECURITY to PUBLIC. I can see my flash drive on my network, navigate to the folder, but when I try to copy the files over from my PC, it just says COULD NOT FIND THIS ITEM. How do I copy files to the boot drive?!

This is a thing that you have to solve, I really can't help with that.

The steps that you've described should be correct as far as I can tell.

 

You can also copy it via SSH so to speak on Windows with something like WinSCP and on Linux with sftp:// for example.

Is there documentation for that somewhere?

The original maintainer compiles the i915 module from here:

https://github.com/strongtz/i915-sriov-dkms
 

I think there should be also a build script somewhere in his Git repository, but most certainly my build steps are a bit differently because I‘ve already included the build from the module into my build toolchain so that the driver is compiled automatically the next time a new Unraid version is released and I will post the package here again.


I had to also issue a PR to the repository because it wouldn‘t compile against the Kernel 6.1.49

 

A user already reached out to me that he plans on continuing maintaining the plugin and I offered to build the module.

 

But the basic steps are:

  1. Install the build tools
  2. Compile the Kernel
  3. Compile the Module
  4. Pack it up

go in your  "Main Tab" in the Unraid GUI, scroll down to flash, then the "browse" button next to "flash" maneuver to the wanted folder and then "upload" the files :D  had to tdo the same.

For all who are in need of a plugin package for Unraid 6.12.4 here it is:

i915-sriov-6.1.49-Unraid.txz 922.96 kB · 50 downloads

i915-sriov-6.1.49-Unraid.txz.md5 33 B · 49 downloads

 

To install them do the following:

  1. Make sure that you are on Unraid 6.12.3 and that you have the SR-IOV plugin from @zhtengw installed
  2. Execute these commands from a terminal (just copy/past them in one go) : 
    mkdir -p /boot/config/plugins/i915-sriov/packages/6.1.49/
sed -i '/  modprobe i915 enable_guc=7/ s/.*/  modprobe i915 enable_guc=3 max_vfs=7/' /boot/config/plugins/i915-sriov.plg
echo "# disable autoload old i915 module on boot
  blacklist i915" > /boot/config/modprobe.d/i915-sriov.conf

     

  3. Copy the two files from above in the folder: /boot/config/plugins/i915-sriov/packages/6.1.49/
  4. Trigger the upgrade process to 6.12.4 from the Update OS page
  5. Reboot

 

This is a pretty manual process but it should work. :)

Make sure that you are on Unraid 6.12.3 and that you have the SR-IOV plugin from @zhtengw installed

But i couldn't install SR-IOV plugin from @zhtengw, because it say Can't download i915-sriov module Package for kernel v6.1.49, how to force install this plugin?

My bro; for starters, thank you so much. But I show 'No Intel graphics found" error. I followed these steps, I do have SR IOV enabled in bios, 12th gen i9-1200k. 
I removed plugin, removed from previous apps, shutdown Unraid for 2min, I followed these steps, and repeated process several times to no avail. 
Hoping you can help me out; you don't know how appreciative we all are for you!

That's most certainly caused because you have a second GPU in your system and on most motherboards this will disable the iGPU.

Please make sure that you've set your primary GPU to the iGPU in the BIOS, if that also doesn't work you have to connect a HDMI Dummy plug (or Display) to your motherboards HDMI port to enable it <- this is not necessary for most boards.

Yes, because your iGPU is disabled because of your second GPU in your system, please check your BIOS settings as explained above.

Took me a while to commit to dealing with the potential downtime if there were any issues, but this all worked like a dream first time thanks. 

Record server reboot time as well 😂

How do you view this setup page you posted here? My plugin isn't clickable.  I followed the same commands in your post as well.  The VF's show up for me, so I know its working.

It should be under settings, I'm not sure what causes it to be there as it showed for a bit even when the plugin was not installed during the upgrade.

Your experience speaks volumes. The Dummy plug did it the trick, even after hours of research I couldn't figure out why I couldn't enable primary display to iGPU; Thank you so much for helping getting it enabled and working, truly. And thank you very much for the plugin @zhtengw I really hope to figure out these other issues.

The problem I am experiencing now is two-part - It takes some tinkering to get the VM up to where I can utilize it - but when I can get it working in one of these two ways, I have these issues:

1. I was able to passthrough Intel igpu to previous VM, solo:
- enable a virtual display with "usbmmidd_vv2" & remote in with Splashtop Desktop; but the screen goes black when I do anything extensive (i.e. change from 1090x1080 to 2560x1440 or add a second display).
- example 1 tower-diagnostics-20231002-1315.zip

2. When I passthrough: GPU 1 - 'Virtual' & GPU 2 - 'Intel';
- I can see the iGPU in the VM but it is not active. The driver seems to be up-to-date.
- example 2 tower-diagnostics-20231002-1439.zip
- This issue here would be ideal to fix first. 

I am not sure if I should bind the VF's at boot, or what is the proper way to get it working. I am getting these errors in the VM logs. 

char device redirected to /dev/pts/0 (label charserial0)
qxl_send_events: spice-server bug: guest stopped, ignoring
2023-10-02T18:08:11.528775Z qemu-system-x86_64: VFIO_MAP_DMA failed: Invalid argument

If there's anything i can do that might be helpful please let me know. Much appreciated.

Update: After keeping it running in the background a couple days it runs okay and I am able to remote in with no issues. BUT when I turned off another VM & booted another, the Splashtop display went black & and I cannot access it in parsec. 
So issue #1 above is a server/plugin related issue possibly and seems to be unrelated to the VM itself being underpowered or overdriven... (tower-diagnostics-20231004-0028.zip)
. TY
